The BERMAD model PC1-400Y-3UM is an elastomeric, hydraulic, line pressure operated deluge valve, designed specifically for advanced fire protection systems, and the latest industry standards. The PC1-400Y-3UM is activated by a 3-way solenoid valve, which actuates a latching relay valve, to open the main valve. Once open the main valve will not close until locally reset. The optional valve position indicator can include a limit switch suitable for Fire & Gas monitoring systems. The PC1-400Y-3UM is ideal for systems with open nozzles for water or foam discharge, available with electric components to suit any hazardous location.
Operation
(for Illustration Only)
The BERMAD model PC1-400Y-3UM is held closed by water pressure in the control chamber [1]. Upon release of pressure from the control chamber, the valve opens. Under NORMAL conditions, water pressure is supplied to the control chamber via the priming line [2] strainer [3] and restriction orifice [5] and is then trapped in the control chamber by a check valve [4], manual emergency release [6], and a relay valve (URV-M) [7] that is held in the supply position by hydraulic pressure supplied through a three-way solenoid valve [8]. The water pressure trapped in the control chamber holds the diaphragm against the valve seat, sealing it drip-tight and keeping the system pipes dry. Under FIRE conditions, water pressure is released from the control chamber, either with the manual emergency release, or by the URV-M switching to the release position in response to the solenoid valve being activated by the fire & gas control system [C].This latches the PC1-400Y-3UM deluge valve open, allowing water to flow into the system piping and the alarm device.
System Installation
A typical installation of the BERMAD model PC1-400Y-3UM features automatic actuation via a relay valve and three-way solenoid valve, triggered by a signal from a fire & gas control system or an on-site emergency pushbutton. When fitted with a limit switch, the valve can send a feedback signal to a remote valve position monitoring system.
Suggested Specifications
The deluge valve shall be UL-listed and FM-approved, 25-bar/365-psi rated, with a straight-through, Y-type-body. The valve shall have an unobstructed flow path, with no stem guide or supporting ribs. Valve actuation shall be accomplished by a single-piece, rolling diaphragm bonded with a rugged radial seal disk. The diaphragm assembly shall be the only moving part. The deluge valve shall include a latching relay pilot valve, a 3-Way solenoid valve FM approved for 25 bar/365 psi working pressure with a tolerance of 35% below of the rated voltage, a Y-type strainer, a ball drain valve, an automatic drip-check with manual override, 4-inch pressure gauges, and a manual emergency release housed in a stainless-steel box. The valve shall be equipped with a protective-covered, dual-color, rotational position indicator visible readable 50 meters, and with two limit switches enclosed in a protective switch box. Removing the valve cover for inspection and maintenance shall be in-line and not require removal of the control trim. The deluge valve and its entire control trim shall be supplied pre-assembled and hydraulically tested by a factory certified to ISO 9000 and 9001 quality assurance standards.
