It is a type of check valve used to regulate the flow of fluids in a piping system. It allows flow in only one direction and prevents backflow.
Swing Check Valve
Swing Check Valve: One-way flow, guaranteed.
The swing check valve is a simple yet essential component of pipes, ensuring that liquid flows only in one direction. The valve body is hinged with a disc. When forward flow pushes against the disc, it swings open to allow smooth passage. As soon as the flow stops, the disc swings back onto a seat, preventing any backflow.
Freture's swing check valves are popular across multiple industries due to their low pressure drop and ease of maintenance. They are used in various applications such as water and wastewater systems, HVAC systems, and petrochemical plants. Valve discs and seats can be designed to meet specific requirements, and some valves incorporate levers, weights, or springs to optimize performance.
