The Jamesbury® Valv-Powr - VPVL double-opposed piston actuators combine the benefits of high cycle life, a rugged construction, and an extremely compact and symmetrical design with a unique range of features and options. They are specifically designed for fast efficient operation of ball, butterfly, and other rotary type valves.

 

 

To select an actuator for a particular valve and service, first determine the maximum operating torque that will be required from the applicable valve bulletin. Then refer to the appropriate torque output table and select an actuator that will, at the available supply pressure, provide a torque output no less than the required operating torque for the valve. For spring-return units, both the spring torque and the air torque must exceed the required operating torque for the valve.

(1) The above times are based on the following conditions: A) Room temperature , B) Solenoid valve orifice diameter of 4 mm (5/32 in.) and a flow rate capacity of 400 L/min (14.1 cfm), C) Minimum inner piping diameter of 8 mm (5/16 in.), D) 5.5 bar (80 psi) air supply pressure, E) Without valve loading.

 

 

 

Direct-mounted solenoid valves are available in both 3-way and 4-way configuration, which mount directly to the actuator in accordance with NAMUR and VDI/VDE 3845 standards, excluding the VPVL650, 700 and 800. In general, 3-way solenoids are used for spring-return actuators and 4-way versions for double-acting.
