Easytork Pneumatic 1/4 Turn Vane Actuators

Easytork's patented spring-less internal air resevoir pneumatic vane actuator is the world's smallest and lightest pneumatic actuator for fail-safe and one of the most efficient actuators in the market.

Compared to a spring & diagphram actuator for control valves, our patented control actuator is 1/10th the weight, 1/6th the size, uses 1/4th of air, has better than/equal to benchmark test performance, and is significantly more cost effective.

Accessories / Ancillaries to Complete Your Valve Automation Needs


Easytork Solenoid Valve (ESV)

Patented solenoid valve covers a full range of applications including NEMA 4, Ex-Proof, ATEX EX, I-Safe, Low-Temp, and Low Power. From 24VDC, 120 VAC, and 240 VAC.

Easytork Air Pilot Valve (EPV)

Even with a third party solenoid valve, users can convert EVA double-acting actuator to fail-safe through Easytork's patented air pilot valve.

Easytork Namur Trip Valve (NTV)

Installing or not installing Easytork’s NTV with a double-acting positioner determines what function (fail-safe, in open or close, or double-acting) the actuator has. Any 4-20ma or 3-15 psi double acting positioner in the market works with the system.

Limit Switches

Easytork offers a full range of NEMA 4 and explosion proof applications.

Lockout & Partial Stroke Test

Integral add on to EVA actuators without adding hysteresis to valve connection.

Declutchable Gear Operator (Updated May '19)

High strength and high torque.

Mounting Hardware

When direct-mount is not an option, our adaptable shafts, drive inserts, and brackets eliminate need for couplers and their associated costs and mechanical issues. Easytork mounting hardware will not cause stem side loading and protects actuator valve stem from leakage.

Easytork is the proud recipient of the Frost & Sullivan New Product Innovation Award in the pneumatic actuators market
