General
“AE” 65mm diameter gunmetal gate pattern dry riser landing valve comes with female BSPT screw (Fig.140) and flanged (Fig.141FG) inlet connections. This valve is generally intended to be installed in a building dry riser system.
The design and construction of the hydrant valves are strictly in accordance with BS5041 : Part 2 : 1987 and generally to BS5154 : 1991 standards.
The selection of materials for the manufacture of the valve are all corrosion resistant, tough and durable. This ensures the product long-life plus providing an efficient service in the time of need.
The valve metal to metal seating are precisely machined so as to provide the shut-off of the valve to have a watertight sealing.
Every hydrant valve manufactured is hydrostatically tested to 16.5 bars and 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.
The hydrant valve comes complete with standard “black” (“Red” is optional) plastic blankcap and chain. Alternative blankcaps made of brass or gunmetal are also available upon request.
