Description
A Swing Check Valve, also known as a non-return or one-way valve, is designed to control the flow direction of water in pipeline systems. It operates automatically without any external mechanism or control system.
The internal disc swings open when water flows in the forward direction and closes automatically when reverse flow occurs, preventing backflow and protecting the system from damage.
This valve is commonly installed in fire protection pipelines, especially between water mains and private fire service systems or at fire pumper connections. Its simple design, reliable operation, and low maintenance make it a preferred choice for industrial and fire safety applications.
