Reduced pressure setting of 14 psi and relief setting of 30 psi for two-story buildings; slightly higher setting for 3-, 4- or 5-story buildings. Maximum inlet working pressure is 100 psi. Combines a pressure reducing and regulating valve, positive relief valve and bypass valve into one compact unit.

Note: For backflow prevention of boiler water into the potable water supply line, install a BFP dual check valve.
