Corrosion Resistance Deluge Valve Aluminum Bronze Diaphragm Style FM

DV-5 Deluge Valve
Aluminum Bronze
Diaphragm Style
 
General   Description  
The TYCO 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.

 
NOTICE
 
The DV-5 Deluge Valves described­ herein must be installed and maintained in com-pliance with this document and with the applicable standards of the National Fire Protection­ Association, in addition to the standards of any Other authorities having­ jurisdiction. Failure to do so may impair the performance of these devices­.

The owner is responsible for maintain­ ing their fire protection system and devices­ in proper operating condi-tion. Contact the installing contrac-tor or product manufacturer­ with any questions.

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.

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.
