DE/EL/HRV/PR Electrically or Hydraulically actuated Deluge Pressure Reducing Valve

 Electrically or Hydraulically actuated Deluge Pressure Reducing Valve (UL)

Electrically or Hydraulically, 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 water pressurized sensor line,
releasing a hydraulic relay, or by an electric command. 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/EL/HRV/PR-MR)

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