PN16
Swagelok KPR1GRA412A20000 is a single-stage stainless steel pressure reducing (PR) regulator designed for precise and reliable gas or liquid pressure control. Part of the KPR series, this compact regulator provides excellent accuracy, sensitivity, and setpoint pressure stability. It features a 316 stainless steel body and an X750 diaphragm sensing mechanism, making it suitable for applications requiring durable performance under high inlet pressures up to 3600 psig (248 bar). The regulator is configured with a 0.06 Cv flow coefficient and 1/4 in. Female NPT ports to ensure consistent downstream delivery with minimal droop.
