The H44H is a flanged cast steel swing check valve that opens with forward flow and closes as the flow subsides or reverses. Its hinged disc provides an automatic non-return function without an external actuator.
The listed configuration uses a WCB body and disc. Product specifications, reference prices and dimensions are provided below for project and replacement enquiries.

Swing Disc Construction
The hinged disc swings away from the seat as forward flow develops. As flow falls or reverses, the disc returns toward the seat to restrict backflow. The valve works automatically, with no external power supply.
The flanged cast steel body provides a familiar installation arrangement for industrial piping. The listed hinge pin and seat materials complete the construction details for this model.
Pipeline Applications
H44H swing check valves are used for non-return duties in water, روغن, gas and utility pipelines where the medium is compatible with the listed materials. Typical locations include pump discharge lines and process branches requiring protection against reverse flow.
Installation orientation and flow conditions influence disc movement. The valve’s flow arrow and installation instructions should be followed during fitting.
