DELUGE VALVE MODEL F-1 STRAIGHT THROUGH STYLE

DESCRIPTION

The Viking Model F-1 Deluge Valve is a quick opening, differential diaphragm, flood valve with one moving mechanism. The Deluge Valve is used to control water flow in Deluge and Preaction sprinkler systems. The valve is held closed by system water pressure trapped in the priming chamber; keeping the outlet chamber and system piping dry. In fire conditions, when the releasing system operates, pressure is released from the priming chamber. The Deluge Valve clapper opens to allow water to flow into the system piping.

Features

• Field replaceable Diaphragm and Seat Rubbers
• Designed for installation in horizontal or vertical position
• Designed to be reset without opening the valve
• Compatible with Hydraulic, Pneumatic and Electric Release Systems

a. Remove all plastic protectors from the openings of the Deluge Valve

b. Apply a small amount of pipe joint compound or tape to the external threads of all pipe connections required. Take care not to allow any compound, tape, or other foreign matter inside any of the nipples or openings of the valve or trim components.

c. Verify that all system components are rated for the water working pressure of the system

4. Hydrostatic Test: The Model F-1 Deluge Valve is manufactured and listed for use at a maximum Water Working Pressure of 250 PSI (17.2 bar). The valve is factory tested at 500 PSI (34.5 bar). Model F-1 Deluge Valves may be hydrostatically tested at 300 PSI (20.7 bar) and/or 50 PSI (3.5 bar) above the normal Water Working Pressure, for limited periods of time (two hours), for the purpose of acceptance by the Authority Having Jurisdiction. If air testing is required, do not exceed 60 PSI (4.2 bar) air pressure.

NOTE: NEVER CONDUCT THE HYDROSTATIC TEST AGAINST THE PRESSURE OPERATED RELIEF VALVE. (PORV) TEMPORARILY REMOVE THE PORV FROM THE TRIM AND PLUG TRIM OPENINGS WHILE CONDUCTING THE HYDROSTATIC TEST.

TRIM NOTE: DISCHARGE PIPING FROM THE AUXILIARY DRAIN VALVE, THE FLOW TEST VALVE, AND ALL SYSTEM DRAINS SHOULD BE KEPT SEPARATE. DO NOT CONNECT THE OUTLET OF THE DRIP CHECK TO ANY OTHER DRAIN.

5. The priming line must be connected upstream of the system water supply main control valve or to a constant source of water at a pressure equal to the system water supply.

6. After the Deluge Valve is set, operation of the Deluge Valve requires the release of priming water from the priming chamber. This may be by automatic or manual operation of the release system. Viking Deluge Valves are compatible with hydraulic, pneumatic, and electric release systems.

a. Hydraulic Release Systems: See Figure 2 for the maximum allowable elevation of hydraulic release piping above the Deluge Valve. If the maximum height of hydraulic release piping exceeds the limit shown in Figure 2, use a Pneumatic or Electric Release System.

b. Pneumatic Release Systems: A Viking Pneumatic Actuator is required between the release system connection provided on deluge valve trim and pneumatic release Piping.

c. Electric Release: Solenoid Valves, System Control Panels, and Electrical Detectors must be compatible. Consult appropriate listing and/or approval guides.

NOTE: FOR OPERATION AT WATER PRESSURES IN EXCESS OF 175 PSI, A 250-PSI RATED SOLENOID VALVE MUST BE USED.

C. Valve Removed From Service

NOTE: WHEN A VALVE HAS BEEN REMOVED FROM SERVICE AND IS SUBJECT TO FREEZING OR WILL BE OUT OF SERVICE FOR AN EXTENDED PERIOD OF TIME, ALL WATER MUST BE REMOVED FROM THE PRIMING CHAMBER, TRIM PIPING, WATER SUPPLY PIPING AND OTHER TRAPPED AREAS.

OPERATION

(Refer to Figure 3)

The Viking Model F-1 Deluge Valve has an inlet chamber, an outlet chamber and a priming chamber. The inlet chamber and outlet chamber are separated from the priming chamber by the clapper (5) and diaphragm (6).

In the set condition:

System pressure is supplied to the priming chamber through a restricted priming line (trim) equipped with a check valve. System water supply pressure trapped in the priming chamber holds the clapper (5) on seat (2) due to area differential design. Clapper (5) separates the inlet chamber from the outlet chamber, keeping the outlet chamber and system piping dry.

In fire conditions:

When the release system operates, pressure is released from the priming chamber faster than it is supplied through the restricted priming line. Water supply pressure in the inlet chamber forces the clapper (5) off from seat (2), allowing water to flow through the outlet and into the system and alarm devices.

Deluge Valves equipped with Conventional Trim:

When the deluge valve operates, the air side of the PORV looses pressure, causing the PORV to operate. When the PORV operates, it continually vents the priming chamber to prevent the deluge valve from resetting even if the open releasing devices close. The deluge valve can only be reset after the system is taken out of service, and the outlet chamber of the deluge valve and associated trim piping is depressurized and drained.

INSPECTIONS, TESTS AND MAINTENANCE

I. Inspection

It is imperative that the system be inspected and tested on a regular basis. The frequency of the inspections may vary due to contaminated water supplies, corrosive water supplies or corrosive atmospheres. Also, the alarm devices, detection systems or other connected trim may require a more frequent schedule. For minimum maintenance and inspection requirements, refer to NFPA 25. In addition, the Authority Having Jurisdiction may have additional maintenance, testing, and inspection requirements which must be followed. The following recommendations are minimum requirements.

A. Weekly -

Weekly visual inspection of the Viking Deluge Valve is recommended.

1. Verify that the Main Water Supply Control Valve (D.1) is open and that all other valves are in their normal operating position and appropriately secured. (refer to Figure 1 and/or Trim Charts and System Data for the system used)
2. Check for signs of mechanical damage, leakage, and/or corrosive activity. If detected, perform maintenance as required. If necessary, replace the device. 3. Verify that the valve and trim are adequately heated and protected from freezing and physical damage.
