Product Summary

Durable Swing Check Valve for Corrosive Environments.

The 316 Horizontal Threaded Check Valve is a robust “Swing Type” non-return valve designed for horizontal pipelines. Made from superior 316 Stainless Steel, it offers excellent resistance to chemicals and saltwater. It allows full flow with minimal resistance and automatically prevents backflow using a gravity-operated disc mechanism.

Product Description

This classic Swing Check Valve operates via a hinged disc that swings open with forward flow and drops shut when flow stops. It is designed specifically for horizontal installation. The interior is accessible via a screw-top cap for inspection. The 316SS construction makes it a preferred choice for chemical processing and marine environments where 304SS might corrode.
