DELUGE VALVE ASSEMBLY

ential applied through the Clapper Latch which holds the Clapper down in the set position is reduced to below the valve trip point.

NOTE Consult with the Authority Having Jurisdiction regarding installation criteria pertaining to electric actuation circuitry.

The Model F470 Multimatic Deluge Valve is a differential latch type valve which depends upon water pressure in the Diaphragm Chamber (Ref. Figure C-l) to hold the Clapper closed against the water supply pressure. The nominal trip ratio is 2.5 to 1, i.e., the F470 Valve operates (opens) when the pressure in the Diaphragm Chamber is reduced to approximately 40 percent of the water supply pressure.

When the F470 Valve is set for service, the Diaphragm Chamber is pressurized through the trim connections from the inlet side of the system’s main control valve, for example an O.S.&Y. gate valve or butterfly valve (Ref. Figure G-l, G-2, or G-3). Opening of an actuation device, for example the solenoid valve in the Electric Actuation Trim (Ref. Fig. G-3), releases water from the Diaphragm Chamber faster than it can be replenished through the l/8 inch (3,2mm) Restriction in the Dia- phragm Chamber Supply Connection. This results in a rapid pressure drop in the Diaphragm Chamber and the force differential applied through the Clap- per Latch to hold the Clapper down in the set position is reduced to below the valve trip point. The water supply pressure then forces the Clapper open per- mitting water to flow into the system piping, as well as through the Alarm Port to actuate the system alarms (Ref. Figure C-2).

When the system main control valve is closed to stop waterflow into the system, the Clapper will be prevented from resetting by the Clapper Latch until the Rest Knob is pushed inward (Ref. Figure C-3). Pushing the Reset Knob inward will temporarily reposition the Clapper Latch away from the wa- terway and allows the Clapper to drop into the seated position.

Step 5: Connect air source to Valve No. 5 (see Figure No. 1 and Figure No. 4) and fill bladder with air (10 PSI maximum) through Valve No. 5 while displacing waterthrough Valve No. 4. Continue until 25% of the water volume (10% for a horizontal unit) has been displaced.

Water volume is to be measured with the 55 gallon (200 liter) drum.

Step 6: When the required water volume has been displaced, close 1/4" shut-off valveon the regulator to trap air inside the bladder, disconnect the air supply, and close Valve No. 4.* Remove the air regulator.

A 10 PSI (0.7 BAR) air bubble has now been formed within the bladder. This liftsthe excess bladder material off the bottom of the vessel, allowing for uniform expansion of the bladder as the concentrate is pumped in.

Step 7: Prime and connect the concentrate pumping apparatus (see Figure No. 2 and 4)and to Valve No. 7, as shown above. Use a Centrifugal Pump or Pneumatic Operated Diaphragm Pump.

Step 8: Remove the water hose from the 55 gallon (200 liter) drum, and terminate to drain.

Step 9: Start the concentrate pump, open Valve No. 4, then Valve No. 7, pumping concentrate into bladder.

*If Valve No. 4 is left open at this point, water will continue to flow out, reducingthe pressure in the bladder.

The concentrate displaces the shell water. If tank pressure steadily decreases, it will benecessary to partially close Valve No. 4 to slow down the discharge of water. If tankpressure steadily increases, it will be necessary to partially (or fully) open Valve No. 4 toallow the pressure to drop back to 10 PSI (0.7 BAR). Slowing the pump discharge will alsolower the tank pressure.

When approximately 75% of the nominal charge has been attained, (90% for horizontaltanks), shell water will stop flowing and the tank pressure will begin to exceed 10 PSI (0.7BAR).

Step 10: Partially open 1/4" shut off at Valve No. 5 to vent and slowly allow air pressure todrop to 0 PSI while continuing to pump the concentrate to the rated capacity.

IMPORTANT: IF CONCENTRATE OVERFLOWS FROM VALVE NO. 5, DRAIN BACKSEVERAL GALLONS TO ALLOW FOR EXPANSION OF AGENT. FILL ONLY TO RATEDCAPACITY! OVERFILLING MAY DAMAGE THE BLADDER!

Step 11: Close Valve No. 7, shut off the pump, and remove 1/4" valve and gaugeassemble from Valve No. 5.

SIGHT GAUGE PROCEDURE

Step 12: Open Valves No. 3 and No. 9, and allow sight gauge to fill. Mark level for futurereference. Close sight gauge valves No. 3 and No. 9 and drain concentrate fromtube by opening valves No. 7 and No. 3. (Note: Make sure all pressure is ventedoff from valves 4 & 5 before opening sight gauge valve No. 3). After concentrate is completely drained, close valve No.’s 3 and 7.

CONCENTRATE LEVEL CHECK

AFFF LEVEL CHECK (Refer to Schematic on Page V830d)

Step 1: Close Valve No.’s 1 and 2 to isolate tank.

Step 2: Attach a hose to Valve No. 6 and terminate to drain. Be aware that the tank maybe under pressure.

Step 3: Open Valve No. 6 carefully to relieve pressure. Once pressure is relieved, fullyopen Valve No. 6, draining water from the shell, then slowly vent Valve No.’s 4 and 5.

Step 4: After the water has completely stopped draining, open Valve No.’s 3 and No. 9.Observe sight gauge level (Figure 7).

a. If the level is normal, follow the "Shell Water Refill Procedure" on page V830l..

b. If the level is below normal, add concentrate (per the "Refill Procedure" on page V830l),to the desired level. Again, follow the "Shell Water Refill Procedure" on page V830l.

c. Close Valve No.’s 3 and 9. Drain concentrate from the level gauge by closing Valve No. 9 and open slowly Valves No. 7 and No. 3.

Step 5: After concentrate is completely drained, close valve No.’s 3 and 7.

ATC CONCENTRATE LEVEL CHECK (Refer to Schematic on Page V851f)

Steps 1-3: The same as above.

Step 4: When water has completely stopped draining, open Valve No.’s 9 and 3. Observe the sight gauge level (because of the thick viscosity of ATC, allow time for level to rise).

Step 5: Repeat (a) and (b), as above.

d: Drain concentrate from the level gauge by closing Valve No. 9, then slowly open Valve No.’s 7 and 3 (Figure 7).

Step 6: After concentrate is completely drained, close ValveNo.’s 3 and 7.

NOTE: BECAUSE OF THE THICK VISCOSITY OF ATC FOAM, THE SIGHT GLASS MAY NOT ACCU-RATELY MEASURE THE LEVEL. TO DETERMINE THE AMOUNT OF CONCENTRATE INSIDE THE UNIT,CONTINUE TO FOLLOW THE PROCEDURE ON "CONCENTRATE LEVEL CHECK," BUT MEASURE THEAMOUNT OF WATER DRAINED FROM THE SHELL.

EXAMPLE: THE DESIGNED CAPACITY OF A 6000 HORIZONTAL UNIT IS 6000 LITERS, THE ACTUALCAPACITY IS 6300 LITERS. IF 600 LITERS OF WATER IS DRAINED FROM THE SHELL, 5700 LITERSOF CONCENTRATE REMAIN. CONSULT VIKING FOR ACTUAL CAPACITIES OF TANKS.
