ARI® SAFE 12.902 Full Lift Safety Valve PN16 DN150/250
Instant overpressure relief for uninterrupted process safety in steam and gas systems.
The ARI® SAFE 12.902 Safety Valve responds instantly to pressure surges in steam and gas systems. In particular, the PN16 pressure class and the DN150/250 nominal diameter options cover a wide range of applications. In addition, the EN-JL1040 cast iron body and 1.4021+QT stainless steel trim increase durability.
When system pressure exceeds the set value, the spring mechanism opens automatically and discharges the fluid. Moreover, when pressure returns to normal, the spring force reseats the disc onto the seating surface for a tight seal. Therefore, this full lift design ensures rapid discharge, prevents system damage and keeps process safety continuous.
