OCV 127-420, a pressure reducing/sustaining/check valve, reduces a higher upstream pressure to a constant, lower downstream, and prevents the upstream pressure from falling below a predetermined minimum. If downstream pressure becomes greater than upstream pressure, the valve will close fully to prevent reverse flow. This valve is applicable anywhere a pressure must be reduced to a manageable level and the upstream system must be protected from low pressure.
