Product Description
Easytork EVA-0411 1" Vane Actuator Valve, EVA Series
PN: EVA-0411
The Easytork EVA-0411 is a double-acting vane actuator with 343 in-lb of double-acting torque at 80 psi and 219 in-lb of fail-safe torque at 80 psi. It has a standard drive insert of 11 mm (0.43 in) square. Easytork describes the EVA as the most compact, efficient, and accurate quarter turn pneumatic rotary valve actuator. Vane actuators operate by introducing a fluid or gas to either side of its enclosure through inlet/outlet ports, creating the force required for movement. Advanced vane actuators utilize double sided vanes that allow for pressurization of both sides, allowing for bi-directional movement.
