● Type of connection: inlet with compression or weld end forconnecting steel tube; male threaded outlet (with gasket)
● Carbon steel valve: NBR, temperature rating: -35℃~+100℃
● Stainless steel valve: FPM, temperature rating: -25℃~+180℃
● Max. working pressure: see “Table of Technical Data”; see P65 for pressure ratings of bright ferrules
● Cracking pressure (tolerance: ±25%): 0.2 bar (standard);0.5 bar (for oils and other high-viscosity liquids);
3 bar (optional); <0.06 bar (for -Q type)
● RZ-*-Q check valve: low cracking pressure; applicable to:1> micro-pressure; 2> vacuum; 3> applications where the
check valve vibrates and whistles due to low gas flow.
