The back pressure control valve shall function to prevent the upstream pressure from falling below a predetermined minimum while closing to prevent reverse flow. The OCV 108-3 has a wide range of applications - anywhere a system must be protected by pressures that are too high (relief) or too low (sustaining), and reverse flow must be prevented. Typical examples include:
– Pump systems
– Fuel distribution systems
