Product Description
General Description

The TYCO DV-5 Deluge Valve with Remote-Resetting Trim is a quickopening, hydraulically operated, differential-type valve designed for fire protection system service. For use as an automatic water control valve in a deluge fire protection system, this diaphragm-style valve can be opened and closed during a full-flow condition from a remote location. Key features of the DV-5 Deluge Valve with Remote-Resetting Trim include the following: • Remote-resetting feature provides the ability to reset the valve from one or more locations. • Compact, space-saving design reduces valve room footprint and construction costs. • Electric actuation is compatible with many types of automatic and manual release options. • Actuation of fire alarms upon system operation is provided. The automatic resetting feature of this valve provides for easy, remote resetting of a deluge system without having to open a valve hand-hole cover. Simply re-pressurizing the Diaphragm Chamber resets the valve. Operation of the DV-5 Deluge Valve with Remote-Resetting Trim is provided by an automatic electric detection system or remote manual electric activation. The easily installed trim configuration for the DV-5 Deluge Valve with Remote-Resetting Trim provides for emergency (manual) release of the valve at the valve location.

Materials of Construction
NOTICE
The Rilsan* coating for the DV-5 Deluge Valve with Remote-Resetting Trim provides corrosion resistance and is intended to extend the life of the Valve when exposed to internal and external corrosive conditions. Although the Rilsan coating is 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 suitability of this coating for a given corrosive condition. Deluge systems using a seawater or brackish water supply require special considerations in order to extend the life of the valve and trim. This type of system ideally should be configured with a primary source of clean fresh water and only upon system operation is the secondary water supply (seawater or brackish water) allowed to enter the system. After system operation, the system should then be thoroughly flushed with clean fresh water. Following this recommendation can increase the service life of the DV-5 Deluge Valve with Remote-Resetting Trim. Deluge Valve • Body and Hand-Hole Cover RILSAN* coated ductile iron per ASTM A 536-77, Grade 65-45-12 • Diaphragm Nylon fabric reinforced, natural rubber per ASTM D 2000
