DeZURIK Knife Gate Valve Actuators

DeZURIK Knife Gate Valves are available with a wide choice of actuators including handwheel, chainwheel, bevel gear, pneumatic cylinder, hydraulic cylinder or electric motor actuators. 

DeZURIK Knife Gate Valve Cylinder actuators are designed with a removable and replaceable cartridge assembly that houses the wear components for ease of maintenance. The cylinder tube is glass wound, vinyl ester, epoxy impregnated fiberglass. Standard seals are acrylonitrile butadiene (NBR). For higher temperature applications, fluoro rubber (FKM) seals with the standard fiberglass tube, or steel tubes can be specified. For corrosion resistance, stainless steel components are available. All cylinder actuators are cycle tested to 50,000 cycles and are mounted to a heavy duty cast superstructure in carbon steel or stainless steel to minimize corrosion. 

DeZURIK cylinder actuators are available with double acting pneumatic or hydraulic cylinders for on/off or positioning services. DeZURIK cylinder actuators are available with pneumatic or electronic positioners on KGC V-Port knife gate valves for throttling control. Positioners are enclosed and mounted on the superstructure.
