ARI® SAFE P 35.921 Proportional Lift Safety Valve PN40 DN65

Gradual pressure discharge for safe and precise protection in high-pressure lines.

ARI® SAFE P 35.921 Safety Valve protects systems and equipment against excessive pressure in industrial plants. In addition, its proportional lift principle discharges pressure gradually, therefore preventing sudden shocks. Furthermore, it offers a reliable solution particularly in steam, gas, and liquid lines. PN40 pressure class and 450°C maximum operating temperature make it resistant to demanding conditions.

This safety valve is manufactured with a 1.0619+N cast steel body and EN-JS1049 ductile iron bonnet. Moreover, the internal parts are made of 1.4021+QT stainless steel, while the seat and disc are respectively 1.4571 (AISI 316Ti) and 1.4122 (AISI 420) stainless steel. As a result, the valve provides long-lasting performance when system pressure exceeds the set point.
