Swing Type Check Valve
The Swing Type Check Valve from Hitech Valves is designed to prevent reverse flow by using a free-swinging disc that closes automatically under backpressure. Its full-flow construction minimizes pressure drop, making it suitable for medium- to high-flow industrial applications.
This valve is widely used in water pipelines, oil & gas lines, chemical plants, fire-fighting systems, pump discharge lines, and general utility services.
