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 with flanged inlet connections.
The design and construction of the landing valves are strictly in accordance with BS5041:Part 1 and the requirements of BS9990:2015.
The valve is suitable for connection to a high-pressure water supply of up to 25 bar (362 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.
Valve body is hydrostatically tested to 30 bar. The Seat is tested at low pressure (1 bar) and high pressure (25 bar).
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 gunmetal are also available upon request.
