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.
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.
In the spring-closed actuator, the adjusting screw provides a convenient means of obtaining valve closure when line pressures are higher than expected.
Suitable for either pneumatic or water hydraulic operation, the unit can be mounted in vertical, horizontal or any intermediate position.
