ARI CHECKO-V 35.003 Lift Check Valve PN40 DN80
Reliable non-return protection for high-pressure steam and process lines.
ARI CHECKO-V 35.003 Lift Check Valve PN40 DN80 automatically stops reverse flow in industrial fluid lines. In addition, its 1.0619+N cast steel body and 1.4021+QT stainless steel disc offer high resistance to wear. Furthermore, with a maximum operating temperature of 450 °C, it acts as a critical safety element in steam and process lines.
The lift operating principle raises the disc against spring force when flow begins, allowing passage. Moreover, when flow stops or back pressure occurs, the spring presses the disc onto the seat to close the line tightly. Therefore, it prevents pressure fluctuations and contamination caused by reverse flow.
