Swing check valve
The Swing Check Valve features a hinged disc that swings open under forward flow and closes automatically when flow reverses. Its streamlined flow path minimizes pressure loss while providing dependable backflow prevention, equipment protection, and long-term operational reliability for water, oil, gas, steam, and chemical applications.
Swing check valve
The Swing Check Valve is one of the most widely used non-return valves in industrial piping systems. Designed with a pivoting disc mechanism, the valve opens automatically when fluid flows in the intended direction and closes instantly when reverse flow occurs.
Its simple yet durable construction offers excellent sealing performance, low flow resistance, and minimal maintenance requirements. Suitable for horizontal and vertical installations (with upward flow), the valve is extensively used in water treatment, oil & gas, petrochemical, power generation, HVAC, and industrial processing systems.
As a professional industrial valve manufacturer, we provide comprehensive OEM and ODM services for customers worldwide.
Our Swing Check Valves are manufactured under strict quality management systems and comply with international standards:
