Swagelok KCY1ERF412A20000 is a stainless steel 2-stage pressure reducing (PR) regulator designed to provide reliable pressure reduction while minimizing droop. The dual-stage configuration helps improve accuracy and maintains a constant downstream pressure, even in applications where the inlet pressure varies significantly. This regulator features a 0 to 50 psig (3.4 bar) control range, 1/4 in. female NPT ports in an F configuration, and a PCTFE seat.
