Flanged Lift Check Valve

H41H flanged lift check valve provides automatic non-return protection for steam, water, oil, and compatible industrial pipeline systems. Its guided lift-disc design offers fast closing response, reliable sealing, and stable operation for pump, compressor, HVAC, and general industrial applications.

PRODUCT DETAILS

The H41H Flanged Lift Check Valve is designed to provide automatic non-return protection in steam, water, oil, and compatible industrial pipeline systems.

The valve operates automatically without an external actuator. Forward flow lifts the disc away from the seat, while reverse flow or pressure loss causes the disc to return to the seat and stop backflow. The guided lift-disc structure provides stable movement, a short closing stroke, and reliable sealing.

The standard configuration is designed for horizontal pipeline installation with the bonnet upright. A spring-loaded option can also be supplied where faster closing response or vertical installation is required.
