Product Description
Nylon Coated Ductile Iron Aluminum Bronze Model DV-5 Deluge Valves
General Description
The Aluminum Bronze DV-5 Deluge Valves are available to provide an alternative material of construc-tion to that of the standard nylon coated ductile iron DV-5 Deluge Valve described in Technical Data Sheets TFP1305, TFP1335, and TFP1338. Available in 2 thru 8 inch (DN50 thru DN200) Flange x Flange end connec-tions, Aluminum Bronze DV-5 Deluge Valves are diaphragm type valves designed for vertical or horizontal installation. They are used as auto-matic water control valves in deluge fire protection systems. The alternate materials of construction are offered for use in corrosive environments where the standard nylon coated ductile iron would not be suitable, i.e. situa-tions where the system is continuously charged with sea water.
The diaphragm style design of the DV-5 Valve allows external resetting, pro-viding for easy resetting of a deluge system without having to open a valve handhole cover to manually reposition a clapper and/or latch mechanism. Simply re-pressurizing the diaphragm chamber resets the valve.

Deluge Valve
Components for the 2 thru 8 inch (DN50 thru DN200), DV-5 Deluge Valves are shown in Figure 1. The DV- 5 Valves are for vertical or horizontal installa-tions, and they are rated for use at a maximum service pressure of 250 psi (17,2 bar).
The Aluminum Bronze DV-5 Deluge Valve is provided with custom manu-factured flange connections (thickness, outside diameter, bolt circle, bolt holes, raised or flush faced) in accordance with most recognized flange specifica-tions. For example:
•ANSI B16.5 (Class 150)
•ANSI B16.42 (Class 150)
•ISO 7005-2 (PN10)
•ISO 7005-2 (PN16)
•JIS B2210 (10K)
•AS2129 (Table E)
The take-out dimensions are shown in Figure 3.
Threaded port connections of the Alu minum Bronze DV-5 Deluge Valves are available NPT threaded or threaded per ISO 7-1.
Materials Of Construction
NOTICE
The materials of construction for the Aluminum Bronze DV-5 Deluge Valve provide corrosion resistance and are intended to extend the life of the DV-5 Valve when exposed to inter nal and external corrosive conditions. Although the materials of construction for the Aluminum Bronze DV-5 Deluge Valve are intended to resist corrosion, it is recommended that the end user or other technical expert familiar with conditions at the proposed installation be consulted with respect to the suit-ability of this coating for a given corro-sive condition.
Body
Aluminum Bronze AB2 per BS1400 (UNS C63000).

Operating Principles
The TYCO Aluminum Bronze DV-5 Deluge Valve is a diaphragm style valve that depends upon water pres-sure in the Diaphragm Chamber (Ref. Figure 2A) to hold the Diaphragm closed against the water supply pres sure. When the DV-5 Valve is set for service, the Diaphragm Chamber is pressurized through the trim connec tions from the inlet side of the sys-tem’s main control valve. Opening an actuation device, releases water from the Diaphragm Chamber faster than it can be replenished through an 1/8 inch (3,2 mm) restriction provided 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 Dia-phragm to hold the Diaphragm in the set position is reduced below the valve trip point. The water supply pressure then forces the Diaphragm open per-mitting water to flow into the system piping.
