Fail-Safe Operation For Ball Valves - Plug Valves - Butterfly Valves - Dampers
Flow-Quip Rotary Series actuators are designed to provide direct mounted, compact, powerful fail-safe automation
for a wide range of quarter turn valves and dampers. Flow-Quip's wide range of rotary actuators eliminate
the need for stored air, high pressure natural gas or nitrogen power sources, therefore field
maintenance can be substantially reduced. They are always ready for emergency service and they can be
frequently operated for normal automation duty. All Rotary units utilize a powerful self-contained electrohydraulic
power module that pressurizes the hydraulic cylinder(s) and causes actuator rotation. The module is enclosed in a weatherproof lockable enclosure which has
an easily removable cover should maintenance be needed. A wide range of rugged high duty motors and electrical
ratings are available to meet the requirements of the application. Torque is produced by a scotch-yoke torque
mechanism with a sealed center body for high torque output. A direct mounted limit switch and a high visible
position indicator beacon give actuator position indication.
SR Series actuators incorporates an electric motor hydraulic
drive to stroke the valve in one direction, and a powerful
self contained spring to stroke the actuator in the opposite
direction. The security of spring return operation gives SR
Series actuators high reliability and mechanical simplicity.

SE Series actuators utilize an electric motor driven hydraulic
power module to generate and store hydraulic energy. When
sufficient pressure is held in storage the system stops the motor
and it maintains a stand by mode until more hydraulic energy
is needed. When fail-safe operation is required hydraulic energy
is drawn from the self-contained accumulator storage and
operates the actuator. After operation the power module again
regenerates stored energy for future stroking needs. Multiple
operations of the actuator are possible utilizing stored energy.
Even without electrical power 2,3,4 or more fail-safe actuator
operations can be achieved with SE Series actuators.

The M-DRIVE Series is powered by a bi-directional motor
driven hydraulic pump to stroke the actuator in both directions.
Using DC motors and simplified hydraulic circuitry the MDRIVE
Series is a cost effective solution for systems with stand by battery systems for fail-safe operation.
manPOWER actuators utilize a powerful self-contained manual
hydraulic module that pressurizes a hydraulic cylinder and
causes actuator rotation. A powerful self-contained spring
strokes the actuator in the pposite direction. The hydraulic
module may be enclosed in a weatherproof lockable enclosure
which has an easily removable cover should maintenance be
needed. Torque is produced by a scotch-yoke echanism with
a sealed center body.
