ARI SAFE P 12.921 Proportional Lift Safety Valve PN16 DN40
Controlled pressure relief that protects equipment and extends service life.
ARI SAFE P 12.921 Safety Valve controls pressure relief in industrial systems with a gradual, proportional lift. In addition, this proportional action prevents sudden blow-offs and therefore extends equipment life. Furthermore, it suits steam boilers and pressure vessels where stable overpressure protection is essential.
The body and cover use EN-JL1040 cast iron, which resists high temperature and pressure. Moreover, internal parts are stainless steel: 1.4021+QT (AISI 420), seat 1.4571 (AISI 316Ti), and disc 1.4122 (AISI 420). Consequently, corrosion resistance remains high. The flanged PN16 DN40 connection simplifies installation, and the valve withstands temperatures up to 300°C.
