General Description
This electrically actuated, remote reset deluge valve is designed for fire protection systems controlled by a Fire Alarm Control Panel and actuated by a solenoid valve as the automatic release device. The basic control valve type used in this deluge system is a direct-sealing diaphragm actuated hydraulic control valve engineered specifically for use in Fire Protection systems. The system includes a 3 way solenoid valve and a 2 way relay as the interface between the Fire Alarm Control Panel - monitoring heat, smoke or flames - and the deluge valve. The deluge valve opens instantly when the control chamber is vented, under one of the
following conditions:• The normally open solenoid valve is energized,
(or the coil of a continuously energized ED 100% normally closed solenoid is de-energized for SIL 3-4 rated systems)
• Opening the manual emergency release valve.In both instances the valve will open, allowing water to spray from all open sprinklers and/or nozzles over the protected area.Resetting, maintenance and periodic testing instructions must be followed as described in detail in the relevant Dorot DE/RC model's IOM (Installation, Operation & Maintenance Manual).

Typical electrically actuated system layoutDorot's DE/RC electrically actuated deluge valve is held shut drip-tight in its stand-by set position. When the solenoid valve is actuated, the deluge valve's control chamber is vented through the 1/2" hydraulic relay. The deluge valve opens, allowing water to flow into all of the open sprinklers and/or nozzles over the protected area.

Ordering Guide
Specification for Engineers The valve shall be electrically actuated, hydraulically operated, direct elastomeric diaphragm-seal, single-chamber globe weir type. The valve shall consist of three major components: the body, cover and the diaphragm assembly. The diaphragm shall be the only moving part. The diaphragm forms a sealed control chamber in the upper portion of the valve, separating operating pressure from line pressure. Packing glands and/or stuffing boxes are not permitted and there shall be no shafts, discs, bearings or pistons operating the main valve. No hourglass-shaped disc retainers shall be permitted and no V-type, U-type or other slotted type disc guides shall be used. The valve shall contain a nylon reinforced rubber diaphragm elastic & resilient through its entire surface without vulcanized radial discs. The diaphragm shall not be guided by any shafts or bearings and shall not be in close contact with other valve parts except for its sealing surface. Maintenance, disassembly and reassembly of all the valve’s components shall be made possible on site and in-line, without the need to remove the valve from the line. Standard material valves such as Ductile Iron (ASTM A-536 65-45-12) and Cast Steel (WCB A-216) should be coated with zinc-enriched, high-built fusion-bonded epoxy (FBE) and a UV protective topcoat conforming to EN12944 C4 & C5 high & very high corrosivity protection grades. Naval quality / very high corrosivity protection grade conforming to EN12944 C5M is available upon request. Other coating standards such as NORSOK or ANSI/NACE as well as coatings for special material valves such as austenitic Stainless Steel (CF8M/ASTM A-316 ) and Nickel Aluminum Bronze (ASTM B-148) can be supplied upon request. The valve should be UL listed under category VLFT for fire protection service.
Please specify in addition to the above:• Electrical features other than standard (24VDC, IP65/Nema4) • Control trim material other than standard (brass/copper) • Required standard/certifications and approval
