Pneumatic Actuators

Actuated Diaphragm Valve
Diaphragm Valve with Pneumatic Actuator (Normally Closed)
Diaphragm Valve with Pneumatic Actuator (Double Acting)

KDVs range of modular actuators is available in 7 sizes to suit Weir Type and Straight Through Type diaphragm valves from DN15-DN250.  Available in normally open, normally closed and double acting configuration, these units boast high linear thrust with very low air consumption. Our modular actuators can be fitted with a range of accessories for adjustment, control and regulating.

 

Compact - Low Profile

With a specially designed flat-top bonnet, KDVs modular actuators are a rugged, totally enclosed close coupled unit with extremely low over-all height.

 

Wide Selection

Actuators furnished in seven sizes to provide more efficient and economical use of available operating air pressures up to 200 psig.

 

High Air Pressure/Longer Stroke

High air pressure capability and long stroke provides greater flexibility in valve/actuator selection. Our smallest modular actuator (Size 0) has more than double the stroke of its nearest competitor.

 

Low Air Consumption

Our unique design features extremely low air consumption - in most instances, less than half that

of our competition.

 

Adjustability

In the spring-closed actuator, the adjusting screw provides a convenient means of obtaining valve closure when line pressures are higher than expected.

 

Adaptability

Suitable for either pneumatic or water hydraulic operation, the unit can be mounted in vertical, horizontal or any intermediate position.
