ARI® SAFE 35.902 Full Lift Safety Valve PN40 DN20/40

Full lift protection that keeps critical high pressure systems safe.

The ARI SAFE 35.902 Safety Valve guarantees safety in high pressure and temperature controlled systems. In addition, its PN40 pressure class and 450°C maximum operating temperature handle demanding industrial conditions. Therefore, it opens fully during sudden pressure surges and protects the system quickly. Moreover, its flanged connection type offers easy installation.

The working principle is simple: when system pressure exceeds the set value, the valve opens automatically and discharges excess pressure. On the other hand, when pressure returns to normal, closing occurs automatically. As a result, the full lift design maximizes flow capacity and increases the safety margin. The body is 1.0619+N cast steel, while the seat is 1.4571 (AISI 316Ti) stainless steel.
