Pressure Restricting Hose Valves | American Fire Supply

Pressure Restricting Hose Valves. Pressure restricting hose valves are used to restrict the pressure of flowing water up to 175 PSI. They are angle hose valves with preset orifices which restrict the volume of water and thereby lower the pressure of the flowing water. NFPA requires restricting valves where the inlet pressure exceeds 100 PSI.
