S-9104H - Henry - Oil Reservoir Pressure Valve 3/8" Flare 20 PSI

The Henry S-9104H is an oil reservoir pressure valve with a fixed 20 PSI (1.4 barg) setting, used in low-pressure oil management systems on refrigeration racks. It is not a reservoir itself. It mounts on the oil reservoir and is piped to suction.

How it works

The valve vents pressure from the oil reservoir to suction while holding a positive pressure differential between the reservoir and the compressor crankcase. That differential keeps oil flowing to the oil level regulators. A higher setting increases the oil return rate; for the lowest differential see the S-9104 (5 PSI).
