PRODUCT DETAILS
The H44H Flanged Swing 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 swings the hinged disc away from the seat, while reverse flow or pressure loss causes the disc to return to the seat and prevent backflow.
The swing-disc design provides a large flow area and relatively low pressure drop, making the valve especially suitable for medium and large-diameter pipelines. Counterweight-assisted or spring-assisted closing configurations can also be supplied where faster closing response or reduced water hammer is required.
