Cast Iron Flange Swing Check Valve Metal Seated for Water Oil & Steam

The cast iron flanged swing check valve is designed to prevent reverse flow in pipeline systems by automatically closing with the pressure of the fluid. Manufactured from high-quality cast iron with a durable metal-seated disc, this valve offers reliable sealing performance and extended service life, even under demanding operating conditions. Its flanged end connection ensures easy installation and secure integration with standard pipeline configurations.

This swing check valve is widely used in water supply, oil transmission, and steam pipeline applications, providing stable flow control, corrosion resistance, and minimal maintenance requirements. The smooth internal flow passage reduces pressure loss, while the robust hinge mechanism guarantees consistent operation and dependable backflow prevention. Ideal for industrial facilities, mechanical systems, and general pipeline networks, this valve delivers long-term reliability and cost-effective performance.
