CYLINDER ROTARY ACTUATORHIGH TORQUE
SCOTCH-YOKE TYPE
The double acting and Spring return Cylinder actuators are powerful, highperformance pneumatic actuators that provide positive modulation or on-off operation for rotary stem motion type control valves and many other quarter-turn (90°) rotating
- · The PROVAL pneumatic actuator series was engineered and produced
to provide maximum torque output with minimum supply pressure. - · Simplicity, reliability and economy being at the top of the list of
design parameters. - · The PROVAL actuator is suitable for any quarter turn application
such as ball, plug, butterfly valves or dampers, in both On-Off and Modulating
heavy duty service.
