Double-Interlock Pre-action, Pressure Reducing Manual-Reset, Electric-Pneumatic Release System

• Model 68-DE\EL\PORV\PR-DN
• Model 30U-DE\EL\PORV\PR-DN

Electrically and Pneumatically, Pilot-controlled, Deluge/Pre-Action, Double-Interlocked valve, actuated by the pipeline pressure. The valve is closed in its normal, set position and opens when the pressure drops in a gas-pressurized auxiliary sensor-line, sensed by the relay-valve, and a solenoid-valve is energized. When tripped, the valve regulates to a steady, pre-set downstream pressure, regardless of upstream pressure or flow rate fluctuations. The valve must be manually reset following actuation. An emergency manual release valve is fitted as standard.
