Product Description
Easytork EVA-0411, 3/4" Vane Actuator Valve, EVA Series
PN: EVA-0411
The Easytork EVA-0411 is a double-acting vane actuator that is part of the EVA series of quarter turn pneumatic rotary valve actuators. The EVA series is designed for industrial and municipal markets. The EVA-0411 is springless-return and has a standard drive insert of 11 mm (0.43 in) square. Vane actuators work by introducing gas or fluid through ports on either side of the actuator's enclosure, creating the force needed for movement. More advanced actuators use double-sided vanes to allow for pressurization on both sides, resulting in bi-directional movement.
