OCV 108-4, a pressure relief/sustaining valve, prevents main line pressure from exceeding a predetermined maximum and prevents the upstream pressure from falling below a predetermined minimum. The valve shall be equipped with a 2-way solenoid valve that will allow the valve to open when energized/deenergized. The valve is applicable anywhere a system must be protected from pressures that are too high (relief) or too low (sustaining), combined with a need for on/off electrical operation.
