Technical Data Sheet – Y Pattern Lift Check Valve

Model: DN8-PN40 Y Pattern Lift Check Valve

1. Product Description

The Y Pattern Lift Check Valve is a spring-loaded, automatic non-return valve. Its Y-shaped body provides a straight-through flow path with low pressure drop, while the lift-type disc ensures rapid, positive closing when flow reverses. Designed for DN8 and PN40 rating, it is suitable for high-pressure systems in compact piping layouts.
