ARI® SAFE 35.901 Full Lift Safety Valve PN40 DN80/125
Fast, reliable overpressure protection for steam and pressure vessel systems.
ARI SAFE 35.901 Full Lift Safety Valve is a critical safety component for steam boilers and pressure vessels. In addition, its full lift design delivers rapid discharge during sudden pressure surges. Therefore, it opens automatically once system pressure reaches the maximum set value and releases excess pressure.
The 1.0619+N cast steel body guarantees durability under high temperature and pressure, while the flanged connection simplifies installation. Moreover, 1.4021+QT stainless steel internals and FDSiCr/51CrV4 spring material provide high corrosion resistance. As a result, the valve achieves long service life at maximum working temperatures up to 450 °C.
