China Tyco DV-5 Diaphragm for Deluve Valve

TYCO DV-5 Diaphragm for deluve valve
General Description
The TYCO 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 supply 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 reduces valve room footprint and construction 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 electric 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 forces the Diaphragm open, permitting water to flow into the system piping and through the Alarm Port, actuating system alarms.
When the Deluge Valve is activated, system outlet pressure is determined by the Pilot Valve's set point. The Diaphragm regulates downstream pressure 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 other configurations, contact a TYCO Representative.
