Threaded Horizontal Swing Check Valve

The Threaded Horizontal Swing Check Valve is an automatic flow control valve designed to ensure the unidirectional flow of media in pipelines. Its compact, non-penetrating swing arm mechanism and investment-cast body offer reliable sealing, low fluid resistance, and excellent compatibility across diverse industrial applications.

This valve is particularly suited for smaller pipe sizes due to its internal threaded connection and various material options.

⭐ Key Structural Features

Anti-Leakage Design (Emission-Free): The swing arm and closing mechanism are entirely housed inside the valve body and do not penetrate the casing. This eliminates external leakage points, ensuring reliable sealing and eliminating the risk of media escaping.
Investment Casting Quality: The valve body is formed using the Silicon Sol Precision Investment Casting process, which yields a smooth, aesthetically pleasing, and dimensionally accurate structure.
Stable Sealing: Features a resilient seat sealing structure, ensuring light and smooth opening/closing action with stable and reliable sealing performance.
Low Flow Resistance: The swing-type design ensures that the valve offers low fluid resistance when fully open, promoting efficient media flow.
Easy Maintenance: The valve’s simple, reliable structure allows for quick installation and maintenance in-line.
