ARI® SAFE 55.901 Full Lift Safety Valve PN40 DN65/100
Automatic overpressure protection for demanding process conditions.
The ARI SAFE 55.901 Safety Valve automatically protects systems from excessive pressure. In addition, its 1.4408 stainless steel body and 1.4571 trim deliver superior corrosion resistance. Therefore it is a reliable choice in chemical and petrochemical plants. Furthermore, the PN40 rating supports high pressure loads.
A spring mechanism opens the disc and seat to discharge fluid in a controlled manner. Moreover, when pressure returns to normal, spring force closes the valve. Consequently this cycle extends equipment life and prevents system damage, so process safety continues without interruption. The valve has flanged connections, DN65/100 nominal size, and a maximum operating temperature of 400 °C.
