Pressure Sealed Check Valves are designed for high-pressure, high-temperature applications across various fluids, except where severe coking is a concern. With their robust material selection, they provide excellent performance in steam-generation stations, industrial chemical plants, and thermal power plants. Available in Cast Steel and Forged Steel body designs, these valves are an excellent choice for diverse application requirements. Their efficient flow passage and superior sealing features ensure low emission service, while their compact structure offers weight savings and easy installation. Additionally, these valves are designed for in-line maintenance, ensuring minimal downtime and long-lasting service.

Features of Pressure Sealed Check Valve

» Backflow Prevention: The cast steel swing check valve is designed to prevent backflow in the line, allowing for flow in a straight line through the valve, which minimizes pressure drop.
» Efficient Operation: The valve's disc swings into the open position as the media flows through the line. Back pressure holds the disc in the closed position to prevent reverse flow.
» Versatile Installation: Suitable for installation in both horizontal and vertical lines, the valve must be positioned according to the flow direction arrow marked on the body to ensure proper function.
» Customizable Options: Accessories such as bypasses, locking devices, and counterweights are available to meet specific customer requirements, enhancing the valve's functionality for various applications.
