2" or 1¼" Pilot Operated On-Off Valve
Both the 1751 2" Oil Stop Valve and the 1147 1¼" Oil Stop Valve are designed for rotary screw air compressor application. The pilot port must be connected to compressor discharge upstream from the minimum pressure valve and preferably to the wet side of the oil-separator. The inlet port must be connected to the downstream side of oil coller, thermal valve, etc. to provide 5 and 8 psi respectively between the pilot and the inlet.
