Cylinder Actuators

On-Off Cylinder Actuators

DeZURIK cylinder actuators are available with double-acting pneumatic or hydraulic cylinders manufacturer for on-off or posi-tioning services. Supply pressure is 50 or 80 psi (340 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 for throttling control. Positioners are enclosed and mounted on the superstructure. Refer to DeZURIK bulletin 80.01-4 for positioner ordering.

Electric Motor Actuators

DeZURIK KGU Urethane Knife Gate valves can be furnished with electric motor actuators including Limitorque Auma, Rotork, E.I.M. and others. They may be specified with cast iron, ductile iron or aluminum housing and in a variety of electrical characteristics.

Ordering

When ordering electronic motor actuators, specify valve order code, shutoff pressure, service conditions-flowing media and installation direction; type of application-on-off or throttling; speed of operation; NEMA rating-4,7, sub- mersible, etc.; electrical characteristics-voltage and phase; actuator accessories and controls as per specification requirements. 6
