ARI® SAFE 35.902 Full Lift Safety Valve PN40 DN50/80

Delivers fast, full-opening protection against sudden pressure surges in critical processes.

ARI SAFE 35.902 Full Lift Safety Valve is a critical safety element that protects industrial plants from overpressure. In addition, its PN40 pressure class and DN50/80 flanged connection ensure reliable discharge in high-pressure steam and process lines. Furthermore, the 1.0619+N cast steel body and stainless steel internals provide long-lasting performance.

The full lift mechanism guarantees complete opening during sudden pressure rises. When system pressure exceeds the set value, the valve opens automatically and releases excess pressure. Moreover, when pressure returns to normal, the spring system closes the valve automatically. The FDSiCr/51CrV4, 1.8159 spring material maintains elasticity at high temperatures and withstands a maximum operating temperature of 450 °C. As a result, the system continues to operate in a balanced manner.
