ARI® SAFE 35.902 Full Lift Safety Valve PN40 DN80/125
Instant full-lift pressure relief that protects high-pressure systems at temperatures up to 450 °C.
ARI SAFE 35.902 Full Lift Safety Valve is engineered to protect high-pressure and temperature-controlled facilities. In addition, its full lift design opens completely within milliseconds during sudden pressure surges. Therefore, it delivers dependable protection for steam boilers and pressurized vessels. ARI SAFE 35.902 Full Lift Safety Valve also features stainless steel internal parts that resist corrosion.
The valve opens automatically when system pressure exceeds the permitted level and discharges the excess. Moreover, it closes automatically once pressure returns to normal, keeping the system balanced. The cast steel body (1.0619+N) withstands high temperatures. As a result, safe operation is guaranteed up to 450 °C.
