Lockout & Partial Stroke Test

Pneumatic Actuator Lockout Device & Partial Stroke Test

Integral Lockout & Partial Stroke Test Add-On
Lockout & Partial Stroke Test (“PST”) device can be purchased as a kit and is easily adapted to Easytork pneumatic actuators. Tight tolerance between lockout pin and lockout shaft allows set up in full close or open position and prevent any rotation of the valve. PST mechanically blocks movement to assure that there is no overshoot of test angle. This mechanical design does not use complicated software or fragile wiring and is failure free even with frequent PST testing.

Clean Interface to Ancillaries
Easytork’s lockout & partial stroke testing device does not affect the interface with the valve or ancillaries
