  Operation
   
  The FLUID Model 68 is a quick opening differential diaphragm deluge valve with one moving part. The valve is held closed by the system water pressure in priming chamber, there by rendering the upstream system piping dry. During fire or test conditions, when the releasing system operates pressure is released from the priming chamber allowing the valve to open and to start the flow of water.
   
 
 
 
Engineers Specifications
 
The Deluge valve shall be a UL Listed, diaphragm sealing weir type valve.
The valve shall have an unobstructed flow path with no stem guid or supporting ribs. Valve actuation shall be accomplished by a
fully peripherally supported, one-piece flexible diaphragm. the diaphragm assembly shall be the only moving part.
The valve shall have a removable cover for quick in-line service, enabling all necessary inspection and servicing.
The control trim materials shall consist of S.S.316 tubing and fittings, and plated brass accessories including 2-way solenoid valve,
strainer and Manual Emergency Release.
The trim shall be supplied, pre-assembled and hydraulically tested at factory.
   
  Control Scheme- Electrically operated deluge valve
 
   
   
 
Pressure Relief Valve
 
The valve maintains a pre-set fixed upstream pressure, regardless of downstream pressure or flow rate variations. The valve will be closed drip tight when the upstream pressure is lower than the set value.
Features:
UL certified Fire Pump Relief Valve.
PN16\230psi and PN25\360psi pressure rated valves.
Will regulate from zero to full flow with no need for additional
  throttling plug or by-pass valves.
Same low pressure losses as in the basic valve.
  Simple structure.
Applicable For::
Water, Sea water, Foam solution or Foam concentrate.
   
Pressure Reducing Valve
 
Valve Hydraulic pressure-reducing valve. The valve maintains a pre-set fixed downstream pressure, regardless of upstream pressure or flow rate variations.
Features:
UL certified.
PN16\230psi and PN25\360psi pressure rated valves.
Will regulate from zero to full flow with noneed for additional
  throttling plug orby-pass valves.
Same low pressure losses as in the basic valve.
Simple structure.
Applicable For::
Water, Sea water, Foam solution or Foam concentrate.
   
 
 
   
 
Note:
Provide adequate space around valve for maintanance.
Data is for envolope dimensions, specific component
positioning may vary.
