The confirmed H44H Class 600 swing check valve has a WCB body. The illustrated 12-inch configuration is one example; other sizes are available for inquiry. Its function is to prevent the backflow of the medium in the pipeline. The opening and closing parts are opened or closed by themselves by the flow of the medium and the force.
Flanged Class 600 Swing Check Valve
Class 600 Flange Swing Check Valve
swing check valve is mounted with a disc that swings on a hinge or shaft. The disc swings off the seat to allow forward flow and when the flow is stopped, the disc swings back onto the seat to block reverse flow.
Product Overview
A hinged closure element moves with forward flow and returns toward its seat as flow conditions change, helping prevent reverse flow. The operating arrangement must be checked for the actual piping system. Neither the H44H designation nor the Class 600 label establishes an installation orientation, leakage class or closing-performance guarantee by itself.
Selection and Ordering Notes
- State the required size, Class 600 connection and mating flange and face-to-face details.
- Provide the medium, design and operating conditions and expected flow changes.
- Confirm WCB body material and the actual disc, seat, trim and gasket specification.
- Request approved flow direction, installation orientation and the project's inspection and shutoff requirements.

Frequently Asked Questions
Is the H44H WCB valve limited to the 12-inch size shown?
No. The 12-inch image illustrates one configuration; other sizes can be requested. State the required nominal size and ask for its corresponding drawing and availability.
Does WCB identify the disc and seat materials as well as the body?
WCB is the confirmed body material. Request the actual disc, seat, stem or hinge components, gaskets and other wetted materials separately for the selected model.
Can I install this swing check valve in any direction?
Use the selected model's flow arrow, approved orientation and installation instructions. Provide the intended piping arrangement and flow conditions rather than assuming every orientation or closing behavior is acceptable.
