DRV010/DRV020, 65mm diameter Gun Metal high pressure “bib nose” pattern regulating landing valve is field adjustable which allows the user to set the valve outlet pressure as desired, according to the conditions of the fire protection system in which the valves are installed.
The valve comes flanged before inlet connections.
The design and construction of the landing valve is strictly in accordance with BS5041:Part 1 and the requirements of BS9990:2015. The valve is suitable for connection of a high pressure water supply of up to 30 bar (435 psi) and will provide a reduced outlet pressure which can be set in-situ during testing and commissioning of the fire protection system.
The shut-off of the valve watertight sealing is achieved by using a high quality rubber bonded seat disc which acts as a primary rubber to metal seal, whilst a secondary metal to metal shut-off is also incorporated in the design of the valve.
Every valve manufactured is hydrostatically tested to 22 bars and 30.0 bars for the valve seat and body respectively. The valve outlet static pressure is factory pre-set at 10-11 bars as required in BS9990:2015.
The internal casting finish of every valve is of high quality ensuring a low flow restriction that meets the standards water flow test requirement.
The valve comes complete with standard “red” plastic plug and chain. Alternative plugs made of brass or gun metal are also available upon request.
