ARI® SAFE 25.901 Full Lift Safety Valve PN40 DN50/80
Reliable automatic overpressure protection for demanding steam, chemical and energy systems.
ARI SAFE 25.901 Full Lift Safety Valve delivers reliable protection and automatic discharge in high-pressure systems. Therefore, it safeguards steam boilers, chemical plants and power stations by activating whenever pressure limits are exceeded. In addition, its full lift design responds quickly to sudden pressure surges.
The valve opens automatically once system pressure exceeds the set value and discharges excess fluid. Moreover, when pressure returns to normal, spring force closes it again to maintain tight sealing. The EN-JS1049 ductile iron body and 1.4021+QT stainless steel internals resist corrosion, consequently producing a long service life with low maintenance demand. It is rated PN40 and tolerates temperatures up to 350 °C.
