Duvalco Swing Check Valves are designed with a lever, weight, and protective cover for efficient and reliable operation. The body is constructed from durable ductile iron, and the valve ensures a tight seal suitable for clean water applications. The design allows for smooth operation, preventing backflow while minimising water hammer. These valves are ideal for systems with fluctuating flow and have an operating temperature range of 0°C to 80°C.
