• 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.
• Cast brass with an aluminum handwheel
• U/L listed
• New York City Board of Standards and Appeals approved
• Restricts only under flow conditions
• For use up to 175 PSI
Brass Adjustable Pressure Restricting Angle Valves
18-153 / 18-154
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 link the valve will resume its previous position and no
resetting is necessary.
