Deluge Valve

Model 68 DE/EL-MRFire Protection Div.

General Description

This electrically actuated, local manual-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 elastomeric diaphragm, hydraulically operated control valve engineered specifically for Fire Protection systems. The system includes a 2 way solenoid valve 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 closed solenoid valve is

energized, (or the coil of a continuously energized ED 100% normally open 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.Once the valve opens, the DMR (Dorot Manual Reset) pilot latches hydraulically, causing the deluge valve to remain in a fully opened position, isolating the control chamber from the upstream water supply. After the solenoid is reset, closing the Dorot deluge valve model DE/EL-MR is only possible by pressing the local manual-reset knob until the valve shuts. Following resetting, the deluge valve closes drip-tight and returns to its standby position without requiring the valve to be physically open or performing other complex reset procedures by qualified or skilled personnel.Resetting, maintenance and periodic testing instructions must be followed as described in detail in the relevant Dorot DE/RC-MR model's IOM (Installation, Operation & Maintenance Manual).

Typical electric actuated, local manual-reset system layoutDorot’s DE/EL-MR electrically actuated, local manual-reset 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 ½” solenoid. The deluge valve latches open, allowing water to flow into all of the open sprinklers and/or nozzles over the protected area.

Ordering Guide

Specification for Engineers The Deluge valve shall be 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 and/or reinforcements 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. The electric actuated control trim should contain a push button local manual-reset hydraulic latching pilot to ensure the Deluge valve remains fully open even when the release device (solenoid or any other release device type) is reset to its initial standby position.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.
