Manually Energized Fail-Safe Spring Return Actuators for Quarter Turn Valves and Dampers

For over 35 years Flow-Quip has been know as a leader in valve automation products. Utilizing only the highest standards for quality control, in compliance with ISO 9001:2000 Flow-Quip offers the manPower SSE and PAK series an innovative line of valve actuator products to meet the stringent demands of pipelines and industries around the world.

Flow-Quip manPOWER Series Spring Return Manually Energized Actuators provide high integrity fail-safe operation of quarter turn valves and dampers. They are suitable for shop or field mounting on a wide range of ball, plug and butterfly valves. They offer a cost effective solution for rotary actuator applications where operation is infrequent and torque requirements are moderate.

Each manPOWER Series actuator contains a compact manually operated power supply that provides hydraulic pressure for the powerful scotch-yoke spring return torque mechanism. This self contained design greatly reduces installation time since no field hydraulic tubing runs are needed.

Each actuator can be controlled by electrical control signal(s), pressure pilots or fire sensors. When commanded, the powerful spring cartridge drives the actuator to its fail-safe position.
