H71H wafer lift check valve provides automatic non-return protection in a compact, lightweight design for steam, water, oil, and compatible industrial pipeline systems. Its ultra-thin wafer body and guided lift-disc structure make it suitable for pump discharge lines, HVAC systems, compact skids, and space-limited installations.

PRODUCT DETAILS

The H71H Wafer Lift Check Valve is designed to provide automatic non-return protection in steam, water, oil, and compatible industrial pipeline systems.

Its ultra-thin wafer body is installed between pipeline flanges using through-bolts, providing a much shorter face-to-face dimension and lower overall weight compared with conventional flanged check valves. This makes it especially suitable for compact piping systems, skids, retrofits, and installations where space and weight are important.

The valve operates automatically without an external actuator. Forward flow lifts the guided disc away from the seat, while reverse flow or pressure loss causes the disc to return to the seat and prevent backflow. A spring-loaded configuration can also be supplied where faster closing or vertical installation is required.
