What a Pressure-Reducing Valve Does
Oil moving from the oil separator to the oil reservoir or oil level controls is at a higher discharge pressure. This pressure must be reduced to a pressure slightly higher than the compressor crankcase.
Selecting the Correct Valve
To maintain proper oil return, each of the oil system components must be selected according to the requirements of the overall oil control system.
High Pressure System
If your system has an oil separator with a built-in oil reservoir, you will need one of two models depending on your system; either an A-7, a constant-output valve, or an Y1236C, a variable-output valve.
NOTE: The OCV-20 will only relieve pressure from the reservoir in excess of its fixed set point. Systems with fluctuating suction pressures as a result of compressor unloaders, staging or other suction line controls must be fitted with an pressure-reducing valve with a differential greater than the suction pressure fluctuation, such as the OCV-30. This ensures oil flow from the oil reservoir through the oil level control to the compressor crankcase.
