Pressure restricting valves are used when flowing water pressure needs to be controlled. They
are angle 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. Unlike the pressure
regulating type of valve, the restricting valve has no effect on the static pressure of a system.
The restricting device can be manually by-passed if required by opening the valve fully. This
is accomplished by breaking the "breakable link", which allows the valve stem to rise to the full
open position.
The breakable link also serves as a simple indication of the valve condition and status. If the
valve is opened without breaking the link the valve will resume its previous position and no
resetting is necessary.
•Restricts inlet pressure from 70 PSI up to a maximum of 175 PSI and down to outlet
pressures of 65, 80 or 100 PSI. Outlet pressures may be set below 65 PSI when authorized
by the local authority having jurisdiction. Setting charts are packed with the valve.

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.
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.
