ARI® SAFE 25.902 Full Lift Safety Valve PN40 DN25/40
Instant overpressure relief for high-pressure steam, gas and liquid lines.
ARI SAFE 25.902 Safety Valve reacts instantly to pressure surges in industrial systems. In addition, its PN40 rating and 350°C maximum operating temperature suit demanding processes. It is therefore ideal for safety-critical steam, gas and liquid lines. Furthermore, flanged connections simplify installation.
When the set pressure is exceeded, the spring force is overcome and the disc opens. After excess pressure is discharged, the spring closes the disc again. Moreover, a ductile iron body and stainless steel internals provide superior corrosion resistance. Consequently, system safety is continuously maintained. The spring is FDSiCr/51CrV4, 1.8159.
