Deluge Valve

Deluge Valve

BRISTOL Valve is Hydraulically actuated, pilot operated diaphragm control valve.
The XT-4080 Series Deluge Valve is held closed by sys- tem water pressure trapped in the top cover chamber. When the releasing system operates, pressure is re- leased from the top cover chamber and the dia- phragm assembly moves upward allowing the water to flow into the system.

ADVANTAGES

BRISTOL DELUGE VALVE XT-4080S (Solenoid Controlled) is an ON/OFF control valve which either opens or closes upon receiving an Electrical Signal to the Solenoid Pilot Control. This valve consists of XT-4080 UL-listed Main Valve, a 3/2 way Solenoid Valve, an Auxiliary Pilot and a Manual Release Station.

The Pilot Control System applies line water pressure to or relieves water pressure from the diaphragm chamber of the main valve to close or open the Deluge Valve. It is supplied either Normally Closed (Energize Solenoid to open) or Normally Open (De-energize Solenoid Valve to open)

PNEUMATIC/HYDRAULIC

  • Model No: XT-4080P
  • UL Listed – XT-4080P Size 4″ 6″ & 8
  • Quick response to Air supply to Pilot
  • No Gland Packing
  • Dry Pilot Trim when air is used for sprinkler system

BRISTOL DELUGE VALVE XT-4080P is used for Dry Pilot Trim-Air Operated Deluge System. The valve can be used with direct air supply to the pilot in which case, the Deluge Valve will openin case of Air Pressure Loss. The valve can alsobe used with Solenoid Valve, where air is supplied to Pilot Valve through 3/2 way Solenoid Valve whichkeeps Deluge Valve in closed condition.

In case of FIRE or TEST, the 3/2 way Solenoid Valve is energized, which removes air from the Pilot Valve. This open the Pilot Valve and releases water from the cover chamber of main valve which opens Main Valve – Deluge Valve.
