ARI CHECKO-V 35.003 Lift Check Valve PN40 DN25
Delivers reliable reverse-flow protection in demanding high-pressure and high-temperature processes.
ARI CHECKO-V 35.003 Lift Check Valve PN40 DN25 is a high-quality valve designed to prevent reverse flow in industrial fluid lines. In addition, its cast steel body and stainless steel internals provide dependable performance under harsh conditions. Therefore, it is an ideal solution for ensuring sealing under high pressure and temperature.
This lift-type check valve raises the disc to allow passage when fluid flows in the correct direction. On the other hand, when reverse flow occurs, spring force presses the disc onto the seat and closes the line. Consequently, this mechanism automatically stops reverse flow in the system. The body and cover are made of 1.0619+N cast steel, the disc is 1.4021+QT (AISI 420) stainless steel, and the spring is 1.4310 (AISI 302) stainless steel. It has a flanged connection, DN25 nominal diameter, PN40 pressure class, and a maximum operating temperature of 450 °C.
