DELUGE VALVE – Anti-Columning Pressure-Reducing, Electric or Hydraulic Control

Deluge Valve – Electrically or Hydraulically Controlled, Anti-Columning Pressure-Reducing is designed for deluge fire suppression systems, allowing water to reach the protected area quickly and in a controlled manner. Electric or hydraulic operation supports different detection and activation scenarios. It is used in open-nozzle systems, foam fire suppression applications, transformer areas, chemical process areas and high-risk industrial locations.
 
 
 
This product range offers two reset options: 77DE-EL-HRV-PR-MR with manual reset and 77DE-EL-HRV-PR with remote reset. Its anti-columning design and pressure-reducing function help control sudden flow behaviour and manage system outlet pressure, supporting both rapid response and controlled water discharge in deluge applications.
 
 
 
The valve features a GGG50 ductile-iron body, ISO or ANSI flanged connections, a maximum operating pressure of 300 psi / 21 bar, a maximum operating temperature of 80°C and model-specific solenoid configurations. The 77DE-EL-HRV-PR uses a 3/2-way N.O. 24 V DC solenoid, while the 77DE-EL-HRV-PR-MR uses a 2/2-way N.C. 24 V DC solenoid. Multiple sizes support different fire-protection project requirements.
