Bettis Pneumatic Actuator

BELIMO Holding AG, an international group of companies, is located in Hinwil, Switzerland. The company develops, produces and markets actuators for controlling heating, ventilation and air conditioning systems. Actuators and control valves make up the company’s core business, and it is considered a global leader in motor control for HVAC. Newer products have integrated sensors and control electronics using ASICs.

The company was founded in 1975 as BELIMO Automation AG. BELIMO is an acronym of three German words: “beraten” (advise), “liefern” (deliver) and “montieren” (install). Belimo specialized in actuators, which were delivered in 1976 for the first time. The first sales company was opened in Germany in Stuttgart in 1977. In 1979, the company’s headquarters was moved to Wetzikon, Switzerland.

In November 2002, the company moved into its new manufacturing and administration building in Hinwil, consolidating all sites in the Zurich Oberland region. At the same time, the headquarters was moved to Hinwil from Wetzikon.

In 2013, Belimo expanded its US site at Danbury, Connecticut, to better serve the American markets. It is used for manufacturing, logistics and administration.

In the 1990s, various Belimo subsidiaries were founded: Spain in 1990; Austria, Great Britain and France in 1993 and 1994; Canada in 1995; and Hong Kong in 1997. In the meantime, BELIMO Automation AG became a public company in 1995. In 1998, the company’s name was changed to BELIMO Holding AG.

BELIMO Holding AG employs 2163 people and generated sales of 847 million Swiss Francs in 2022. The company is listed on the Swiss stock exchange (BEAN), and has been since 1995.

In the mid-1980s, representatives in England, Finland, Norway, Austria, Denmark, France, Sweden and the Netherlands became independent distributors. The company expanded with the founding of BELIMO Aircontrols in the United States in 1989. Shipping fees include handling and packing fees as well as postage costs.

For most linear actuators, this travel speed is given as 10 mm/s or something similar. However, if you are going with a heavy-duty linear actuator with a high maximum load capacity, the travel speed will be much lower around 5 mm/s. If you want your furniture or installations to move quickly, it is advised to go with a higher travel speed.The Windy Nation linear actuator offers the highest stroke length in this listicle which is much higher than others. To be precise, you get a stroke length of 750 mm with it. This makes it ideal for all kinds of uses including installing with a windmill.

With a water-resistant linear actuator, you can be assured that it does not get damaged from rain, snow, or other environmental factors. Some of the common water resistance ratings include IP43, IP45, IP54, IP65, and a few others. Out of all these, going with a higher water resistance rating of IP65 is recommended for protection against rain and snow.But since a lot of you may be interested in knowing further, we present you with a buying guide for the best linear actuators. With the following factors in consideration, picking the right linear actuators should be quite easy: Another highly important factor to consider while getting a linear actuator is the stroke length. This tells you the amount of distance you can move a given object. Unlike the maximum load capacity, the stroke length varies a lot between different models out there. As you would expect, different linear actuators have different maximum load capacities. While most of them are rated at a maximum load capacity of 225 lbs for general use, there are also high-performance models supporting up to 600 lbs of weight which is ideal for heavy-duty use.

However, the higher load capacity does result in a lower travel speed of 5.7 mm/s. This travel speed can be an issue when you consider the given stroke length rating of 450 mm. As for the warranty, Eco Worthy includes a 30-day warranty with this linear actuator.KZNANZN is a relatively small brand that develops a wide range of products for your DIY home improvement needs. It is an ideal option if you are looking for affordable products that get your job done.As per the name, a linear actuator is essentially a motor where the post moves forward and backward instead of having a rotational movement like standard motors. This allows you to easily move and automate the movement of different furniture around your home. Even if you are new to these, you can easily pick one by going through the best linear actuators discussed up above.

Coming to its maximum load capacity, it is similar to other smaller linear actuators at 225 lbs. Another similarity between this and other options is the given travel speed of 10 mm/s. However, despite having a pretty sturdy build quality, you only get a 30-day warranty with it.There are a lot of cases where you would be using your linear actuator outdoors. This includes installing a linear actuator for your garage, your solar panels, windmill, or something else. For such installations, it is highly advised to get a linear actuator with a water resistance rating.Whether you want to move furniture inside your home or want to install movable devices outside like solar panels or windmills, a linear actuator can be a great way to automate all of these. Unlike a traditional motor, these linear actuators are made for moving forward and back allowing you to easily move things.

Eco Worthy’s linear actuator comes at the 2nd position of this listicle as you get great performance out of it. Starting with its maximum load capacity, this linear actuator is designed to handle up to 330 lbs of weight with ease.A linear actuator can be used to move a lot of things at your home or workshop for automation. Unlike a standard motor, these linear actuator motors move forward and backward.

You can stop it at any time by just cutting off its power source and it halts just the way it is with a sophisticated self-locking system. This actuator has a 20% duty cycle which means for every minute of work it needs to rest for 4 minutes.

This is combined along with a 300 mm stroke length which should be good enough for those who are on a budget. To ensure that this linear actuator can be used quickly, it uses a travel speed of 10 mm/s. While you do get a 6-month warranty with this budget option, its build quality is a bit on the average side which is to be expected from an entry-level offering.Those of you who are going with a linear actuator with a high stroke length would want it quickly open and close without consuming a lot of time. This is only possible when your linear actuator has a high travel speed. Usually, this travel speed is given in terms of mm/s where a higher rating is always better. As you can tell by its name, Eco Worthy makes products related to green power solutions like its linear actuators made for solar panels that offer great performance. By now, you must know that linear actuators are used to move all sorts of things. But, if you wish to move something heavy, then your linear actuator should be able to handle its weight as well. This can be understood by taking a look at its maximum load capacity.

It is made up of aluminium alloy housing which makes them durable. It comes with an internal switch which turns off automatically in case of motor idling. It has IP54 rating which provides protection against water, dust and corrosion.Apart from these factors, there is still much more to consider before getting a linear actuator. This includes things like their significant specifications and other details along with a comprehensive “Buying Guide” that we have explained in this article.

This linear actuator motor is suitable for wide range of industries that include electric power, chemical industry, construction, mining, lifting, petroleum, chicken coop door and others.If you are using something like a linear actuator that is made for heavy-duty usage, you would want it to last for as long as possible. Even though most of them are quite reliable, it is still a great idea to check the included warranty. Generally, you will find most of them to offer a 1-year warranty or something similarThe Bettis GVO-Series is a field proven linear valve actuator suitable for automating most types of rising stem valves in safety shutdown and control applications.If the valve is located high enough to be out of reach, a chain wheel will be added to the same type of gearbox so that the valve can be operated from the ground. The chain is in a long loop that hangs down to where it can be easily reached. The operator would simply pull down on one side of the chain loop to open the valve, and the other side to close it.

Customer reviews of products and testimonials are also included. A valve actuator is a mechanical device that uses a power source to operate a valve. This power source can be electric, pneumatic (compressed air), or hydraulic (the flow of oil). There are two main types of actuators, one for each of the two main types of valves that require them. They are rotary and linear. Both Vane and Rack-n-pinion style spring return actuators have a descending, linear torque output throughout the air stroke and spring stroke. The slope of the line is caused by the spring force increasing and decreasing as it compresses and expands. Scotch yoke actuators, due to their mechanics, produce curved torque outputs that are inverse on one stroke direction vs. the other.Both are available in dual (shown above) and single versions and both can be spring return or direct acting (sometimes referred to as single acting and double acting).

Both Vane and Rack-n-pinion style double acting actuators have an constant, linear torque output throughout the stroke in both directions. Scotch yoke actuators, due to their mechanics, produce curved torque outputs that are identical on one stroke direction vs. the other.Other aspects of electric actuators that are important to consider include the voltage, duty cycle, wiring entry and connections, and the electrical protection rating according to IP (ingression protection) and/or NEMA (National Electrical Manufacturer’s Association) standards.

The most important aspect of a spring return actuator is that it offers a “fail-safe” position. This means that if the air supply is lost, or electric power to the solenoid that controls the air is lost, the valve will travel to this position using the force of the spring(s). This could be either open or closed, whichever offers a safer outcome.

There is also a 3rd style of pneumatic rotary actuator that is older and far less common – Vane. In this type of actuator the piston is replaced by a vane, which is fixed to the stem drive. The vane is enclosed in a wedge shaped chamber where the stem center is located towards the point of that wedge. Air is forced into this chamber on either side of the vane in order to move it, thus rotating the stem drive.Choosing an actuator and connecting it properly is only half the job done. Equally important is mounting the actuator in a method that is right for your application. Below are two common methods that are used to mount an electric linear actuator.

An actuator is a part of a device or machine that helps it to achieve physical movements by converting energy, often electrical, air, or hydraulic, into mechanical force. Simply put, it is the component in any machine that enables movement.

Naturally, torque is one of the most important aspects to consider in the performance of an actuator. A key factor here is to note that there are two kinds of torque metric to consider, static and dynamic load. Static load torque or force refers to the actuator’s capacity when it is at rest. The dynamic metric refers to the device’s torque capacity when it is in motion.Performance metrics are quantifiable outputs that help you evaluate the quality of a particular product. Actuators can be considered under several performance metrics. Traditionally, most common among them have been torque, speed, and durability. These days, energy efficiency is also considered equally important. Other factors that may be considered include volume, mass, operating conditions, etc.

In the solar power industry, they help in moving the panels to the direction of the sunlight. Even in industries like agriculture, where heavy machinery that uses hydraulic actuators are more common, electric linear actuators are used for fine and delicate movements.Actuators in the market come in different mounting styles and understanding their benefits is necessary before buying an actuator. For instance, a dual-pivot mounting method in a linear electric actuator allows the device to pivot on both sides while extending and retracting. With this, the application gets to have two free pivot points while moving on a fixed path.

They are not just seen in large applications. At home, actuators are the critical devices that help you to set up consoles or cabinets that could hold televisions and can be opened at the touch of a button. They are also seen in TV and table lifts which users can adjust through electric switches or buttons at their convenience.Speed of an actuator differs depending on the weight of the load it is supposed to carry. Usually, the higher the weight, the lower the speed. Hence the speed metric should first be looked at when the actuator is not carrying any load.

Distance, or stroke length as it is technically known, matters here. The stroke length decides how far your object can be moved. Manufacturers often sell actuators of varying stroke length.

Defined simply, an actuator is a device that converts energy, which may be electric, hydraulic, pneumatic, etc., to mechanical in such a way that it can be controlled. The quantity and the nature of input depend on the kind of energy to be converted and the function of the actuator. Electric and piezoelectric actuators, for instance, work on the input of electric current or voltage, for hydraulic actuators, its incompressible liquid, and for pneumatic actuators, the input is air. The output is always mechanical energy.Actuators are present in almost every machine around us, from simple electronic access control systems, the vibrator on your mobile phone and household appliances to vehicles, industrial devices, and robots. Common examples of actuators include electric motors, stepper motors, jackscrews, electric muscular stimulators in robots, etc.

Some actuators are ideal for heavy-duty work in rough environments, but they may not work well when it comes to handling smaller work like packaging which requires precision and the ability to repeat the same action hundreds or thousands of times.Conversely, stationary mounting, which secures the actuator to an object along the shaft, is useful for actions such as pushing a button. At this stage, you should be able to narrow down your options to a significantly smaller pool from where you started. From here, you will need to narrow down further. For instance, linear actuators come in different styles for different kinds of functions. Rod-style, for instance, is the most common and simple among them, with a shaft that expands and retracts. Track style, which does not change its overall length or size during operations are more suited when space constraints are an issue. There are also column lifts and other actuators that would be ideal for setting up TV and table lifts. Factors such as operating voltage and motor type may also be worth considering.

The type of actuator and the manufacturer’s design decides the durability of an actuator. Although those such as hydraulic actuators are considered more durable and rugged compared to electric actuators, the detail specs on the quality of the material used will be up to the manufacturer.

One of the most useful applications of this method is to open and close doors. When the actuator extends, the dual fixed points enable the door to swing open. The action of the door closing and opening causes changes in angle, but the pivot provides ample space for the two mounting points to rotate. While using this method, make sure that there is enough room for the actuator to extend, without any obstacles on its way.Actuators are not something you would read about every day in media, unlike artificial intelligence and machine learning. But the reality is that it plays a critical role in the modern world almost like no other device ever invented.

Does the object you need to move in your project require linear or rotary movement? Linear actuators are useful in exerting a mechanical force that would move an object in a straight line while rotary actuators, as the name suggests, generate circular motion.With increasing concerns on energy conservation and its direct impact on operational costs, energy efficiency is becoming more and more a decisive metric in all kinds of machinery. Here the lesser the quantity of energy required for an actuator to achieve its goal, the better.

The purpose of an actuator is to move or lift an object. Find out, in your case, how much this object weighs. The load capacity of an actuator decides how much it can lift, and although many actuators may look similar, their load capacity will vary. Before you buy an actuator, make sure the weight of your object matches the capacity of the actuator.
