Pneumatic Actuated Valves Supplier in Pakistan

Pneumatic actuated valves pair a valve with an air-powered actuator, opening and closing automatically on compressed air instead of by hand. Fast, repeatable and easily tied into plant control systems, they suit cyclic and remote-operated duty across water treatment, HVAC, chemical and process plants. A. Karimjee & Sons supplies pneumatic butterfly and stainless-steel ball valves with double-acting or spring-return (fail-safe) actuators, for automated on/off and modulating control.

Types We Supply & How to Choose

Pneumatic Actuated Valve Types

Selection guide

Pneumatic Butterfly: Fast, efficient flow control, well suited to water treatment, HVAC and chemical-plant service. See butterfly valves →
Pneumatic Ball: Stainless-steel body for high-pressure resistance and long service life, with tight quarter-turn shut-off. See ball valves →
Double-Acting Actuator: Uses air to drive the valve both ways and holds its last position if air is lost.
Spring-Return Actuator: Moves to a safe fail position — open or closed — automatically on loss of air supply.

Frequently Asked Questions

What is a pneumatic actuated valve?

It is a valve fitted with an air-powered actuator that opens and closes it automatically using compressed air, removing the need for manual operation and allowing remote or cyclic control.

What is the difference between double-acting and spring-return actuators?

Double-acting actuators use compressed air to drive the valve in both directions and hold position if air is lost. Spring-return (single-acting) actuators move to a safe fail position — open or closed — automatically on loss of air.

Which valve types are available with pneumatic actuators?

Butterfly and ball. Butterfly suits water treatment, HVAC and chemical service; stainless-steel ball suits high-pressure, long-life duty.

Can pneumatic valves modulate flow, or only on/off?

Fitted with a positioner they can modulate flow to a set position; without one they operate as on/off. Let us know your control requirement and we will specify accordingly.
