SAGA Single Acting Air Lock Relay holds the Air in locked condition when the supply Air pressure falls below the set value; thereby keeping the Control valve in stay-put condition. The Relay reset automatically to auto mode when the line pressure resumes.

The supply pressure connected to the signal port is sensed by the spring loaded Diaphragm and the thrust developed enable the valve to open thereby Air entering through the IN ports get connected to the output line. The cut off settings is adjustable and can be done by adjusting the screw and locknut.

SAGA Single Acting Air Lock Relays are built very compact to save space. Ideal for precise applications in the pneumatic control loop of Actuator.
