What Is The Application Of A Metal Seated Cast Iron Swing Check Valve?

The metal seated cast iron swing check valve is widely used in water supply, HVAC systems, and low-pressure industrial pipelines where durability and backflow prevention are essential. Its swing-type disc opens with forward flow and swings shut when flow reverses, providing a reliable one-way flow mechanism. The metal seat ensures longevity in systems where soft seats might wear or degrade over time, particularly in slightly abrasive or higher temperature environments. Constructed from cast iron, the valve is both cost-effective and strong, making it suitable for general service use. It’s often chosen for applications involving hot water, cooling systems, and non-corrosive fluids. With its simple design and easy maintenance, this valve offers dependable operation and long service life, especially in systems where flow direction stability and minimal pressure loss are important.
