Product Description
The BERMAD model 400Y-3D is an elastomeric, hydraulic line pressure-operated deluge valve, designed specifically for advanced fire protection systems, and the latest industry standards. The 400Y-3D is activated by a 3-way solenoid valve, suitable for electric fire detection systems. The optional valve position indicator can include a limit switch suitable for Fire & Gas monitoring systems. The 400Y-3D is ideal for systems with open nozzles for water or foam discharge. Available with electric components to suit any hazardous location.

Technical Data
Operation
The BERMAD model 400Y-3D 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], restriction orifice [5] and strainer [3], and is then trapped in the control chamber by a check valve [4], manual emergency release [6], and a relay valve (HRV) [7] that is held closed by hydraulic pressure supplied through a three-way solenoid valve [8]. The water pressure trapped in the main valve 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 HRV opening in response to the solenoid valve being activated by the fire & gas control system [C]. This opens the 400Y-3D deluge valve, allowing water to flow into the system piping.

System Installation
A typical installation of the BERMAD model 400Y-3D features actuation via a hydraulic relay valve and three-way solenoid valve, triggered by a signal from a fire & gas control system or an on-site emergency pushbutton. When open and fitted with a limit switch the valve can send a feedback signal to a remote valve status monitoring system.

Technical Specifications
Suggested Specifications
The deluge valve shall be UL-listed, 25 bar / 365 psi rated, elastomeric type with a straight-through, Y-type body. The valve shall have an unobstructed flow path, with no stem guide or supporting ribs. The valve shall be coated internally and externally creating a corrosion barrier with UV protection. Valve actuation shall be accomplished by a single-piece dual-color rolling diaphragm, bonded with a rugged radial seal disk. The diaphragm assembly shall be the only moving part. The deluge valve shall include a relay pilot valve, a 3-Way solenoid valve with approval for 25 bar/365 psi and a tolerance of 35% below 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 drain socket shall be flanged and have 360 degree swivel. The valve shall be equipped with a dual-color360-degree, rotational position indicator, readable from 50 meters, and with two limit switches enclosed in a protective switch box. Removing the valve cover for inspection or maintenance shall be in line and not require removing 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 standards.
Dimensions and Weights
(1) Refers to the length dimensions for Raised Face ANSI #150, ISO 16 Flanged, Threaded and Grooved valves
(2) Refers to the length dimensions for Raised Face ANSI #300 and ISO 25 Flanged valves
IMPORTANT: Dimensions for the trim envelope or extents refer to a vertical orientation and may vary with specific component positioning; - allow a tolerance of at least ±10%.
