Air Lock Relay-Single Acting

When the supply air pressure falls below the specified value, the SAGA Single Acting Air Lock Relay locks the Air and maintaining the Control valve in the stay-put position. When the line pressure resumes, the Relay automatically resets to auto mode. The spring loaded Diaphragm senses the supply pressure linked to the signal port, and the thrust created allows the valve to open, connecting air entering through the IN ports to the output line. The cutoff settings could also be adjusted by simply altering the screw and locknut. SAGA Single Acting Air Lock Relays are designed specifically to save space
