Operating Pressure 350BAR
Pressure Range 50bar-290bar ,Preset:150bar(check:1.5bar)
Internal Leakage 30ml/min.max.to 80% of norminal setting
Temperature -30°C to +120°C(-22°F to+250°F)
Cavity GZF-1/OR see page K-29
Fluids Mineral-based fluids with viscosities of 7.4 to 420 cSt.
Fast response to pressure surges
Hardened poppet and seat for long life
Adjustment may be locked in place
Industry common cavity
Adjustment prevents spring from going solid
The valve prevents flow from ① to ② until the set crack pressure at ① is
achieved.The poppet then unseat allowing flow from ① to ②
protecting the circuit from over pressurization.When pressure at ②
rises above the springs bias pressure,the poppet is lifted and flow
allowed from ② to ① .
