KF25 flange pressure relief valve for vacuum chamber (< 1.5 Psig) PN_90136701005 margin: 0 20pxPressure relief valve with KF25 NW25 flange. Prevent excessive positive pressure build up in pumps or vacuum chambers. Spring loaded piston pushed open when chamber pressure > 1. 5 psig or 16. 2 psia or 1116 mbar. Spring loaded piston closes when chamber pressure < 16. 2 psia (1. 5psig) or 1116 mbar Piston open @ PISA = 16. 2 psia + 0. 3 PSI or 1. 5 psig + 0. 3 PS.
