Electrically controlled deluge/pre-action pressure reducing valve, actuated by the pipeline pressure. The valve is closed in its normal, set position and opens when a 2w solenoid valve is energized. When tripped, the valve regulates to a steady, preset downstream pressure, regardless of upstream pressure or flow rate fluctuations. It closes drip tight when the solenoid valve is de-energized. An emergency manual release valve is fitted as standard.
