Easytork

Easytork Automation Corp., headquartered at 2505 Metro Boulevard in Maryland Heights, Missouri, designs and manufactures patented spring-less pneumatic rotary valve actuators and complementary valve automation accessories. The company's founding premise is that pneumatic actuation had seen no meaningful technological advancement in over 50 years, and their core innovation — a patented internal air reservoir vane design — eliminates mechanical springs entirely for fail-safe operation. When air supply is lost, stored pressurized air is released to drive the actuator to its fail position. The flagship EVA Series is a rugged pneumatic rotary vane actuator engineered for industrial and municipal isolation valves, and is the only off-the-shelf actuator rated for low-pressure fail-safe operation at 35 psi or below. The ECA Series targets rotary control valves, delivering a 0.7-second full stroke control loop speed that positions it as a direct replacement for spring-and-diaphragm actuators on Fisher control valves. Supporting products include ESV solenoid valves, EPV pilot valves, NTV Namur trip valves, limit switches, lockout and partial stroke test devices, declutchable gearboxes, CVA mounting hardware, and complete automated valve packages. Notably, Easytork actuators can operate using water as the actuation medium, making them suitable for municipal water and wastewater installations. The company holds ISO 9001:2015 certification and received the Frost & Sullivan New Product Innovation Award for pneumatic actuators. A documented mining application achieved a 77% reduction in total cost of ownership compared to conventional spring-return actuators.
