Electrically and pneumatically, pilot-controlled, double-interlock preaction 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 supervisory pilot line, sensed by the relay valve, and the solenoid valve is energized. An emergency manual release valve is fitted as standard. Also available with manual reset: DE\ EL\PORV-DN-MR.
