🚿 ASSE 1003 Direct-Acting vs ASSE 1018 Pilot-Operated PRV (<80 PSI Zones)

Commercial Water PRV Station Calculator

Size high-rise building vertical pressure zone breakdown PRV stations under IPC Section 604.8 & ASSE 1003/1018: calculate low-flow vs high-flow dual-stage pilot-operated pressure reducing valves (restricting domestic water pressure to <80 PSI to protect fixtures from blowouts), check cavitation index (sigma), and master plumbing profits.
