Pneumatic actuators are devices that use air pressure to move or control something

Rotary pneumatic actuator is a special device that uses air pressure to make things turn or rotate. It’s like a power tool that helps to move and control objects by using air.

Valvaire pneumatic actuators, designed for valve control, offer reliability and durability. With pre-lubrication and testing for one million operations, these ISO5211-compliant actuators ensure smooth performance. They feature a visual position indicator, adjustable 90°+ movement, and robust construction. Valvaire actuators are known for their high cycle life, anodized aluminum body, and self-lubricating piston guides. With nickel-plated alloy steel shafts and nitrile seals, Valvaire actuators deliver efficient and precise valve control.

Electric Rotary Actuator

Electric rotary actuator is a device that helps other devices to rotate or turn

Electric Rotary Actuators serve a crucial role in controlling valves that rotate from 0 to 90 degrees, including butterfly valves, ball valves, flapper valves, cock valves, and dampers. Their applications span various industries, such as oil and gas, water treatment, shipping, paper production, and power plants.

These actuators operate using different voltage levels, including 380V, 220V, or 110V AC, or alternatively, 24V or 110V DC power. They function based on a control signal that can range from 4 to 20mA or 0 to 10 VDC. This feature enables the actuator to move the valve to the desired position, thereby achieving automated control.

One of their standout features is their high power output, with a maximum torque output reaching up to 2000 N.m, providing strong and efficient operation.

Valve Monitor APL210N

Valve Monitor APL410N

Valve Monitor

valve monitor is a device that checks and indicates the position (open, closed, or partially open) of a valve in industrial processes.

Valve Monitor is a compact, weatherproof device with internal adjustable position switches and an external visual indicator. It’s designed for use with quarter turn actuators and valves, featuring a NAMUR standard mounting. The monitor comes with an aluminum die-cast enclosure for weatherproof protection. The bracket follows ISO 5211 and NAMUR standards. Various switches, including domestic, Omron, or Honeywell, can be utilized. Additional features include a visual position indicator, a “Quick-Set” cam that doesn’t require tool-based adjustments, dual cable entries, and captive cover bolts to prevent loss during cover removal.

Electric-Pneumatic Positioner

Electric-pneumatic positioner is a device used in industrial control systems to convert an electrical control signal into a pneumatic output

The Valvaire electric-pneumatic valve positioner is an advanced tool designed to bring significant benefits to its users. By interpreting a 4-20mA DC signal from a controller or control system, it precisely controls the position of the valve via a pneumatic actuator, ensuring optimal performance and efficiency in your operations.

One of the standout features of the Valvaire positioner is its built-in LCD display for smart positioners. This provides real-time data directly in the field, enhancing your ability to monitor and adjust operations as needed, thereby improving productivity and reducing downtime.

The Valvaire positioner is engineered to prevent resonance within the frequency range of 5-200Hz. This feature ensures smooth operation and extends the lifespan of the device, saving you maintenance costs in the long run.

The device offers the flexibility of easy switching between forward and backward actions, as well as between single and double actions. This adaptability allows it to fit seamlessly into a variety of operational setups, making it a versatile addition to your equipment.

For smaller actuators, the Valvaire positioner can prevent vibration by reducing the size of the locator orifice. This feature not only improves the accuracy of your operations but also protects your equipment from potential damage caused by vibrations.

Despite its high functionality, the Valvaire positioner is known for its low air consumption. This feature makes it a cost-effective solution, reducing your operational costs over time.

Lastly, the Valvaire positioner allows for half-splitting range control without the need for part replacement. This means less downtime for part changes and more time for productive operations, further enhancing its value to your business.

Ball Valve

At Valvaire, we understand how crucial it is to choose the right type of ball valve for your specific needs. Ball valves, as you know, play a vital role in controlling the flow of liquids and gases in various industrial applications. But did you know that there are several types of ball valves, each with its unique features and benefits?

Now, there are different types of ball valves, and they’re different mainly because of how they’re built and what parts they have. Here are a few our main types:

  • 1 Piece Ball Valve : These are made from one single piece of material. They’re very strong and rigid, but they can’t be taken apart if you need to fix them.

  • 2 Piece Ball Valves: These are like a mix of the first two types. They have two pieces that are put together, but they work in a similar way to the single body valves.
  • 3 Piece Ball Valves: These are made from three separate pieces that are put together. If something goes wrong, you can take them apart to fix the problem.

  • Top Entry Ball Valves: These valves are designed so you can get to the inside parts from the top. This makes them easier to fix if something goes wrong.

  • Welded Ball Valves: These valves are permanently put together by welding. They’re very strong and leak-proof, but they can’t be taken apart.

Each type of ball valve serves a different purpose and is suited to different applications. Understanding these differences can help you make an informed decision about which type of ball valve is best suited to your specific needs.

At Valvaire, we’re committed to helping you find the best solutions for your business. If you have any further questions or need more information about our range of ball valves, please don’t hesitate to get in touch.

Butterfly Valve

Butterfly valves are a type of valve that can control or stop the flow of a fluid.

Here are our main types of butterfly valve

  • Concentric Butterfly Valves: This is the simplest type of butterfly valve. It’s like a door that swings on a hinge right in the middle. This type is used in systems that don’t have very high pressure or temperature.

  • Double-Eccentric Butterfly Valves (High-Performance Butterfly Valves): This type of valve is a bit more complex. The “door” (or disc) is not exactly in the middle, but a bit to the side. This design allows the “door” to swing open without touching the “frame” (or seat), reducing wear and tear. It’s used in systems with a bit higher pressure.

  • Triple-Eccentric Butterfly Valves (Triple-Offset Butterfly Valves): This type is the most complex. Not only is the “door” a bit to the side, but the surface of the “door” is also not flat but angled. This design almost eliminates rubbing contact between the “door” and the “frame,” reducing wear and improving how long it lasts. These are best for systems with very high pressure.

  • Wafer-Style Butterfly Valves: This type of valve is like a thin biscuit sandwiched between two pieces of bread. It’s designed to prevent any backflow in systems designed for flow in one direction.
  • Lug-Style Butterfly Valves: This type of valve has threads (like on a screw) at both sides of the valve body. This allows it to be installed into a system using two sets of bolts and no nuts. This setup lets either side of the piping system to be disconnected without disturbing the other side.

Each type of butterfly valve is used for different pressures and uses. The choice of valve type depends on the specific needs of the system in which it will be used.
