Spring-less Fail Safe Reservoir

This simple patented solution creates a new spectrum of efficiencies to optimize your process and solve chronic & complex problems.

How It Works

Air reservoir tanks are commonly used to emergency shut-down large mission critical valves that would otherwise be too large with springs. Easytork utilizes an internal air reservoir to ensure valve closure, improving on the way springs in a spring return actuator do. When there is air failure, the pressurized air stored in the reservoir is released to drive the actuator to its fail position.
