Fire Protection System (FPS), an HD Fire dealer in Bhopal, supplies HD valves and accessories for fire water and sprinkler pipework: UL Listed and FM Approved butterfly, OS&Y gate and swing check valves, post indicators, test and drain valves and pressure gauges, plus Y-type strainers, pressure reducing valves, zone control manifolds and water motor gongs.
Sizes: 2″ to 12″
Fire protection butterfly valves in wafer, lugged and grooved types with an integral tamper switch, rated for 300 psi. The ductile iron body is fusion bonded epoxy coated, and HD states the valve gives bubble tight shut-off with little pressure drop.
Sizes: 50 to 300 mm (2” to 12”)
Resilient wedge gate valves for fire protection in OS&Y and non-rising stem (NRS) versions, rated for 21 bar (300 psi). The OS&Y type shows clearly whether it is open or shut, and both are UL Listed and FM Approved.
Post indicators that show the position of a non-rising stem gate valve and let it be operated from outside: the HD-IP vertical post for underground valves, adjustable for bury depth, and the HD-WP wall post for valves behind a wall. Both are UL Listed and FM Approved.
Bourdon tube pressure gauges for fire protection systems in a polished stainless steel case that seals against weather, moisture and dust. HDP-1 has a 90 mm dial and phosphor bronze Bourdon tube, and the range is UL Listed and FM Approved.
Sizes: 50 to 200 NB (2” to 8”)
A pilot operated pressure reducing valve for fire protection that brings a high inlet pressure down to a steady, set outlet pressure under varying flow. It comes in 50 to 200 NB with grooved or flanged ends.
A swing check valve that lets water flow one way only, opening when flow pressure exceeds its cracking pressure and closing promptly when flow stops or reverses, to protect the system from back flow and pressure surges. It is UL Listed and FM Approved.
A compact three position ball valve (OFF, TEST and DRAIN) with a drain orifice of K 5.6, or K 4.2 as an option, and a tamper resistant sight glass. It is made of brass to ASTM B584 and is UL Listed and FM Approved.
A hydraulically operated mechanical bell used with fire protection system valves as an outdoor alarm. The gong, cover and motor housing are corrosion resistant aluminium alloy, and it is UL Listed and FM Approved.
Sizes: 2” to 12”
Flanged and grooved Y-type strainers in ductile iron with fusion bonded epoxy coating, rated for 300 psi. A removable cover allows the screen to be cleaned without taking the strainer out of the pipeline, and it is UL Listed.
Sizes: 2.5” to 8”
A sprinkler zone control assembly that brings a flow switch, test drain, system pressure gauge and pressure relief valve together at one point, so each zone's water flow can be monitored and tested. A butterfly valve can be added.
For isolation, choose between butterfly and gate valves. HD butterfly valves use a rotating disc in a compact, light body, come in wafer, lugged and grooved types from 2 to 12 inch, and carry an integral tamper switch that can report a closed valve to the fire alarm system. HD OS&Y (outside screw and yoke) gate valves lift a gate clear of the flow, so pressure loss is minimal when open, and the rising stem shows at a glance whether the valve is open. Buried non-rising stem (NRS) gate valves are operated and checked through an HD post indicator. Gate valve flanges are to ANSI B16.1 or AWWA, or BS EN 1092 PN16, where PN16 is the flange pressure class.
For flow control, the swing check valve opens when flow pressure exceeds its cracking pressure and closes as soon as flow stops or reverses. The pressure reducing valve cuts an inlet pressure of up to 300 psi down to a steady outlet between 3.45 and 13.8 bar (50 to 200 psi), factory set at 8.5 bar and adjustable through its pilot valve. Y-type strainers have a removable cover so the screen can be cleaned without taking the body out of the line.
For monitoring and testing, HD pressure gauges read 0 to 300 psi, test and drain valves combine OFF, TEST and DRAIN in one three position ball valve with a sight glass, and the zone control manifold brings a flow switch, test drain, pressure gauge and pressure relief valve together for one sprinkler zone. A water motor gong gives an outdoor alarm when water flows.
Most of these items are UL Listed and FM Approved (the Y-type strainer is UL Listed), and the ductile iron valves and strainers are to ASTM A536 with fusion bonded epoxy coating. Prices on request: call or WhatsApp +91 92440 89060.
