Valve Actuators

VPVL series double and single acting pneumatic actuators incorporate double-opposed pistons with a rack and pinion drive. They provide the benefits of high cycle life, good corrosion resistance and a flexible compact design with an outstanding range of other performance features.

The QUADRA-POWR® X spring-diaphragm actuator is especially designed to provide safe, reliable operation by air, gas, water, oil or other media, even with minimum supply pressure. Its rolling diaphragm design provides accurate control and is adjustable from both open and closed positions. It also allows field-reversible operation without disassembly - fail open or fail close modes can be switched quickly in the field by simply inverting the actuator

B Series pneumatic cylinder actuators are designed for remote on/off control service. Double-acting (B1C) or spring return open/closed in case of air failure (B1J) are available. The actuators' unique articulated lever crank design provides a torque output signature, which is particularly suited to automating ball and butterfly valves.

Electric actuators for modulating and on/off services. Fail safe position also available.

The rugged design of the Neles M series range of manual valve actuators meets the requirements demanded of industrial environments. Smooth and easy operation is made with high performance axial needle roller bearings. Users can always be sure that use of our manual operator is safe.

Flowserve Automax Supernova series rack and pinion actuators are designed for butterfly, plug, or ball valves, and offer one compact design for double acting and spring return functionality.
