Frequently Ask Questions

What is a Pneumatic Valve Positioner?

A Pneumatic Valve Positioner is a control device that accurately positions a valve based on the input control signal, ensuring precise flow regulation and stable process control.

What industries use Pneumatic Valve Positioners?

They are widely used in Oil & Gas, Chemical, Power Generation, Water Treatment, Pharmaceutical, Food Processing, Marine, and Process Industries.

Who Is a Valve Positioner Supplier in India?

Alis Valves supplies valve positioners for industrial pneumatic control valves, with configurations suitable for different actuator and process-control requirements.

Why is a Valve Positioner used?

It improves valve accuracy, reduces hysteresis, increases process efficiency, and ensures precise valve movement.

What Is the Difference Between a Positioner and a Limit Switch?

A positioner controls and adjusts valve position, while a limit switch provides feedback when the valve reaches a predefined position.

Can Positioners Be Used with Rotary Valves?

Yes. Rotary positioners can be used with ball, butterfly, and other rotary control valves, while linear positioners are used with globe-type control valves.
