DE/HRV/PR Hydraulically actuated anti-columning Deluge Pressure Reducing Valve

 Hydraulically actuated anti-columning Deluge Pressure Reducing Valve (UL)

Hydraulically activated, Pilot-controlled Deluge/Pre-Action
Pressure Reducing 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 sensor line,
tripping a hydraulic relay. When tripped, the valve regulates to a steady, preset downstream pressure, regardless of upstream
pressure or flow rate fluctuations. An emergency manual release
valve is fitted as standard.

Features:
• UL certified
• Simple structure
• Easy installation and maintenance
• Remote reset - optional manual reset (DE/HRV/PR-MR)

Applicable for:
• Deluge or Single-Interlock Pre-Action type valves
• Dry pipe
• Water, Sea water and Foam
