Hydraulically Actuated, Manual Reset Deluge Valve

Hydraulically controlled deluge/pre-action valve, actuated by the pipeline pressure. The valve is closed in its normal, set position and opens when the hydraulic pressure drops in a pressurized pilot line, limited to 7m above the valve (for higher pilot lines, see DEHRV-MR model sheet). The valve must be manually reset following automatic actuation. An emergency manual release valve is fitted as standard.
