Flanged Check Valve

Secure, Standardized Connection for Reliable Backflow Prevention

The Flanged Check Valve is a non-return valve with integrated flanged ends, allowing for quick and secure installation using standard pipeline bolts. It is designed to automatically prevent reverse flow in pipelines carrying water, oil, gas, or chemicals. With a tight shut-off, corrosion-resistant body, and universal compatibility, this valve is widely used in municipal water systems, HVAC, oil & gas, and industrial fluid control.
