ARI® SAFE 55.901 Full Lift Safety Valve PN40 DN50/80
Maximum overpressure protection for demanding high temperature processes.
ARI® SAFE 55.901 Full Lift Safety Valve is engineered for maximum safety under high pressure and temperature, moreover it provides automatic protection against overpressure in industrial plants. In addition, its stainless steel body and cover deliver superior corrosion resistance. Consequently it stands out as a reliable solution, particularly in the chemical, energy and petrochemical sectors.
The spring mechanism opens the valve automatically once system pressure exceeds the set limit and discharges the pressurized fluid in a controlled manner. Moreover, when pressure returns to normal, the disc closes under spring force and restores a safe system condition. This operating principle extends equipment life and prevents possible damage.
