FM SV 1 Deluge Valve List Ductile Cast Iron Automatic Fire Fighting Sprinkler System

SV-1 Deluge Valve Ductile Cast Iron Automatic Fire Fighting Sprinkler System  FM 
The DV-5 Deluge Valve with Remote-Resetting, Pressure-Reducing Trim is a diaphragm-style valve that depends upon water pressure in the Diaphragm Chamber to hold the Diaphragm closed against water sup-ply pressure. Key features include the following:  

Pressure-reducing function maintains pre-set outlet pressure.

Remote-resetting feature provides the ability to reset the Deluge Valve from one or more locations.

Compact, space-saving design re-duces valve room footprint and con-struction costs.

Electric actuation is compatible with many types of automatic and manual release options.

Operation of the DV-5 Deluge Valve with Remote-Resetting, Pressure-Reducing Trim is provided by an automatic elec-tric detection system or remote manual electric activation.

The force differential applied through the Diaphragm that holds it in the set position is reduced below the Valve trip point. Water supply pressure then forc-es the Diaphragm open, permitting wa-ter to flow into the system piping and through the Alarm Port, actuating sys-tem alarms.

When the Deluge Valve is activated, system outlet pressure is determined by the Pilot Valve’s set point. The Diaphragm regulates downstream pres-sure based on this setting.

The Pilot Valve can be used in various applications and configurations, and should be installed according to the Deluge Valve’s application scheme, honoring the Pilot Valve’s working conditions described herein. For oth-er configurations, contact a  Representative.

Listing is based on the following criteria:

Inspection, testing, and mainte-nance requirements referenced in the Standard for Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems, NFPA 25.

Periodic testing of the DV-5 Deluge Valve thereafter in accordance with NFPA 25.
