Deluge Valves: UL and FM Listed UVPPD Supply
ValveAtlas supplies UL Listed and FM Approved UVPPD deluge valves for aircraft hangars, transformer protection, chemical process areas, foam-water suppression and high-hazard spray protection on projects in Toronto, Montreal, New York, Boston and London. The UVPPD is the electrically operated deluge valve with integrated solenoid trip, emergency release, pressure-operated trim and complete factory-trim packaging for wet-pipe-pattern discharge with all open nozzles or open sprinklers.
This page is the technical reference for specifying engineers, EPC firms, and mechanical subcontractors selecting deluge protection on high-hazard systems governed by NFPA 13, NFPA 15 (water spray), NFPA 11 (foam-water), NFPA 409 (aircraft hangars) and BS EN 12845.

How a deluge valve works
The UVPPD is a diaphragm-actuated valve held closed by supply-side water pressure acting on the diaphragm above the clapper. A solenoid valve on the release line electrically opens on a trip signal from the fire alarm control panel. Release of diaphragm pressure allows supply water to push the clapper open and flow to all open nozzles or open sprinklers in the protected area simultaneously.
Unlike wet pipe, dry pipe and pre-action systems, deluge systems use OPEN sprinklers or OPEN water spray nozzles. The piping downstream of the deluge valve is empty (not supervisory air; no supervisory air is required for the valve logic). When the deluge valve trips, water fills the piping and discharges through every nozzle on the zone simultaneously, producing total-area protection.
Factory trim on UVPPD includes: electric solenoid (120V AC or 24V DC) on the release line, emergency release manual station, supply-side pressure gauge, diaphragm chamber pressure gauge, main drain, strainer with flushing connection, alarm line with pressure switch port and water motor gong connection.
Listings and code acceptance
UL 260. UVPPD carries UL 260 (deluge valves for fire protection service) listing. The UL certificate is issued to the manufacturer.
UL listing for Canadian projects. UL listing covers the same SKU under ANSI/CAN/UL 260 for Canadian NFPA 13, NFPA 15 and NFPA 409 projects.
FM Approval. FM Approvals Class 1020 certifies UVPPD for FM-insured high-hazard properties. FM Global and other property insurance surveyors accept the FM certificate on their insured properties.
LPCB and UK acceptance. Where a UK specification or insurer requires LPCB-approved components under BS EN 12845 and the LPC Rules, confirm acceptance of UL/FM-listed equipment with the insurer before ordering.
Where deluge valves are used
Aircraft hangars. NFPA 409 and FM Global Data Sheet 7-93 require deluge protection on hangar floors with Group I, Group II or Group III classification. Foam-water deluge on hangar floors with open foam-water sprinklers (NFPA 11). Airport hangar construction in Toronto, Montreal, Boston and London specifies UVPPD.
Transformer protection. NFPA 15 and FM Global Data Sheet 5-4 require water spray deluge on outdoor and indoor transformers. Open water-spray nozzles (K=1.6 to K=2.0 smooth-bore) discharge at the transformer surfaces to cool the casing and suppress oil fire.
Chemical process protection. NFPA 15 water-spray systems on reactor vessels, storage tanks, loading racks and pumping stations in petrochemical and chemical plants.
Foam-water suppression. NFPA 11 foam-water deluge on flammable liquid storage, truck loading racks and hangar floors with aqueous film-forming foam (AFFF).
Commodity storage rack protection. High-challenge rack storage where in-rack sprinklers cannot be installed; ceiling-level deluge on open sprinklers provides total-area cooling.
Approved-equal submittals
Where a specification names a specific manufacturer, we prepare an approved-equal submittal package (listing certificates, dimensional drawings and material data) for review by the engineer of record and the authority having jurisdiction.

Frequently asked questions
What detection is used with a deluge valve? For aircraft hangars: linear heat detection cable (LHD) at 200 degrees Fahrenheit activation along the entire ceiling. For transformers: UV/IR flame detection. For chemical process: LHD, UV/IR or pneumatic rate-of-rise detection tubing. NFPA 72 covers detection installation. Detection wires to the fire alarm panel, which energizes the solenoid on the deluge release line.
How is the deluge valve reset after trip? After fire department all-clear and system drain-down, the diaphragm chamber is re-pressurized through the priming line from the supply. The emergency release manual handle is returned to the closed position, and supervisory status is restored. No supervisory air is required for the piping (unlike dry pipe or pre-action).
What is the trip time on a deluge valve? UVPPD trips in 1 to 3 seconds from solenoid energize. Water delivery time through the discharge piping depends on pipe length and density; NFPA 15 sets 30-second water-on-target for water-spray systems.
Does the deluge valve have supervisory air? No. Deluge systems use empty piping (atmospheric) downstream of the valve. Supervision is provided by the detection system, not by supervisory air pressure.
Can UVPPD be used for foam-water? Yes. UVPPD combined with a bladder-tank or balanced-pressure proportioner and foam-water sprinklers provides NFPA 11 compliant foam-water deluge. ValveAtlas coordinates the proportioner and foam concentrate supply as a companion package.
