Product Features
» Backflow Prevention: The cast steel swing check valve is designed to prevent reverse flow within the system. As the fluid flows through the valve, the disc swings into the open position, and when there is no flow, back pressure keeps the disc in the closed position. This ensures that flow remains unidirectional and minimizes system disruptions.
» Flexible Installation: These valves can be installed both horizontally and vertically. It is important to align them with the flow direction indicated by the arrow on the valve body for proper operation.
» Customization Options: A variety of accessories such as bypass valves, locking mechanisms, and counterweights can be supplied upon request to meet specific operational requirements.
