ARI® SAFE P 35.921 Proportional Lift Safety Valve PN40 DN100
Staged pressure relief protects high-pressure steam and gas systems from sudden pressure shocks.
The ARI SAFE P 35.921 Safety Valve provides staged overpressure protection in steam and gas lines. In addition, its PN40 pressure class and DN100 flange connection ensure reliable operation in high-capacity systems. Moreover, a maximum temperature tolerance of 450°C makes it suitable for power plants and chemical facilities. Furthermore, the proportional lift principle prevents sudden pressure shocks in the system.
The body is made of 1.0619+N cast steel, while the bonnet is EN-JS1049 ductile iron. In addition, the internal parts are 1.4021+QT stainless steel for high strength. The spring material FDSiCr/51CrV4 (1.8159) provides a long-lasting and stable spring characteristic. Therefore, the valve maintains precise opening and closing sensitivity under all conditions. The seat is 1.4571 (AISI 316Ti) stainless steel and the disc is 1.4122 (AISI 420) stainless steel.
