Oil Stop Valves

Our standard Oil Stop Valves come in two types:

1-1/2″ ORB Threaded • SAE 2″ Flange

Designed to meet ASME Process Piping Code B31.3.

Application and Description

The oil stop valve is design for oil-flooded rotary screw compressor applications. The pilot port is connected to the compressor outlet. The valve is installed in the oil line, preferably downstream of the cooler. On shut down the pilot pressure decreases closing the oil stop. The valve comes in normally closed version so the valve needs to be piloted for oil flow.
