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. The seals are acrylonitrile butadiene (NBR) with a maximum temperature rating of 180ºF (83ºC). For higher temperature applications fluoro rubber (FKM) seals with the standard fiberglass tube are offered with a maximum temperature rating of 275ºF (135ºC). Steel tubes with FKM seals are available for a maximum temperature rating of 392ºF (200ºC) upon request. The minimum standard temperature rating is -58ºF (-50ºC). For corrosion resistance applications, stainless steel components are offered. 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.
On-Off Cylinder Actuators
DeZURIK cylinder actuators are available with double acting pneumatic or hydraulic cylinders for on/off or positioning services. Supply pressure is 60 or 80 psi (410 or 550 kPa). To order, add the proper code from the on/off column of the table to the valve order code. Specify hydraulic media if other than oil.
Positioning Cylinder Actuators
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.
