Application: Persian GPE deluge valves are quick opening hydraulically oper-ated diaphragm valves known as a system control valve in a deluge system. They frequently used for fast application of water in a spray system. Deluge valve protects areas such as power transformer installation, storage tank, convey or protection and other industrial application etc. With the addi-tion of foaming agent they do protect aircraft hanger and inflammable liquid fire as well. Beside these, the Persian GPE Deluge Valves have been satisfactorily evaluated as a Foam Concentrate. Control Valve for use with AFFF or ATC foam in fixed foam/water sprinkler systems.These state of art models have three chambers, isolated from each other by the diaphragm oper-ated clapper and seat seal. While in SET position, water pressure is transmitted through an external bypass check valve and restriction orifice from the system supply side to the top chamber, so that supply pressure in the top chamber acts across the diaphragm operated clapper which holds the seat against the inlet supply pressure because of the differential pressure design. On detection of fire, the top chamber is vented to atmosphere through the outlet port via opened actuation devices. The top chamber pressure cannot be replenished

through the restricted inlet port, and the upward force of the supply pres-

sure lifts the clapper allowing the water flow to the system piping network and alarm devices.

Landing Gate Valve

• Model No.4930• Size 2½ in BS 336• Inlet, Flange Connection• Outlet, BS 336 Male or Female

Application:The design and construction of the landing gate valves are strictly in accordance with BS5041: Part2:1987 and generally to BS5154:1991 standards.The selection of materials for GPE landing gate valve is resistant, though and durable. This ensures the product long-life plus providing an efficient service in the time of need.The valves metal to metal seating are precisely machined so as to provide the shut-off of the valve to have a water-tight sealing.Every landing gate valves is hydrostatically tested to 22.5 bars for the valve seat and body respectively.The internal casting finishes of every valve is of high quality ensuring a low flow restriction that meets the standard`s water flow test requirement.

Features and Benefits:• Compact and elegant design with excellent flow

characteristics.• High quality casting finishes.• Precise machining for metal to metal seating

provides leak-proof.• Corrosion resistant and quality material used

for durability, long-life and efficiency.• Maintenance free. • Different handle types are available upon

customer request.
