Swing Type Check Valves

untitled design (2)

Swing Type Check Valves are designed to allow smooth forward flow while automatically preventing reverse flow through a swinging disc mechanism. They offer low pressure drop, quiet operation, and reliable sealing, making them ideal for water supply, oil & gas, petrochemical, and industrial process lines. Their simple design ensures long service life, easy maintenance, and excellent performance even with low flow rates. Built with durable materials, Swing Check Valves resist corrosion and handle varying pressures efficiently. They are best suited for horizontal pipelines where dependable backflow prevention is essential.
