Both cases of reduced or increased pressure can be controlled with a pressure regulator installed along the sprinkler system main water line. Drip emitters are adapted to work with water pressure around 20 PSI. High pressure around 40 PSI will cause the drip heads to break apart. Rotors are another type that works best at pressures above 30 PSI.

The pressure reducing valve (PRV) is designed to reduce both residual (flowing) and static (non-flowing) water pressure. In contrast, pressure restricting devices (PRDs) are designed to only control residual (flowing) water pressure. This differentiation is vital to understanding the design application and expectations of the system.

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.
