The HoseSafe™ Pressure Regulating Valve is designed to maintain a safe constant outlet pressure irrespective of varying inlet pressure and is suitable for use on sites even where high or low ambient temperatures are experienced. The valve utilises the cast / forged body design of the established Knowsley SK range of wet riser landing valves with the addition of a spring cartridge or element to provide thepressure regulating facility.
The Knowsley SK “HoseSafe” pressure reducing hydrant valve is for use on oil, gas and petro-chemical sites, oil rig platforms or wet rising mains in buildings.
