ARI® SAFE 35.902 Full Lift Safety Valve PN40 DN200/300

Automatic overpressure protection for high-pressure steam and process systems up to 450°C.

ARI SAFE 35.902 Safety Valve guarantees safety in high-pressure steam and process lines. In addition, it provides effective protection against excess pressure in steam boilers and pressurized vessels. Moreover, the PN40 pressure class and 450°C maximum operating temperature suit demanding industrial conditions.

The full lift mechanism delivers fast, complete opening during sudden pressure surges. Furthermore, the flanged connection simplifies installation at DN200/300 nominal diameters. When system pressure exceeds the permitted maximum, the valve opens automatically and relieves excess pressure; consequently, it reseats by itself as pressure returns to normal and maintains balanced operation. The body is cast steel 1.0619+N, while the trim is 1.4021+QT stainless steel, so corrosion resistance and mechanical strength ensure long service life.
