- Pressure restricting valves are used when flowing water pressure needs to be controlled.
- NFPA requires restricting valves where the inlet pressure exceeds 100 PSI. Unlike the pressure regulating type of valve, the restricting valve has no effect on the static pressure of a system.

How it works
- Restricting valves are angle valves with preset orifices which restrict the volume of water and thereby lower the pressure of the flowing water.
- The restricting device can be manually bypassed if required by opening the valve fully. Simply pull the pin to allow the yoke to fall back from the valve stem to allow the valve to be opened fully. When the valve needs to be restricted again, slide the yoke back into place to be NFPA compliant.
