Swing Type Check Valve

The Shoritsu SCV-S Series is a swing type check valve designed to allow forward fluid flow while automatically preventing reverse flow through a hinged disc mechanism. When forward flow is present, the disc swings open against the flow direction. When flow stops or reverses, the disc returns to its seat under gravity and back pressure, providing a positive seal against backflow.

Simple in construction, reliable in operation, and suited to a wide range of pipeline fluids and service conditions, the SCV-S is the standard choice for pump discharge protection, pipeline backflow prevention, and general non-return valve applications across multiple industries.

Features

• Hinged disc design allows forward flow with minimal resistance and closes automatically under reverse pressure or flow stoppage, providing reliable backflow prevention without external actuation
• Low pressure drop across the valve body due to the full bore swing disc design, maintaining system efficiency and reducing energy loss in the pipeline
• Simple construction with minimal moving parts, making the SCV-S straightforward to install, inspect, and maintain throughout its service life
• Available across a wide size and pressure class range from DN15 to DN600 and ANSI CL150 through CL1500, covering the full breadth of pipeline service requirements
• Wide end connection options including flanged, screwed, socket weld, and buttweld to match your pipeline configuration and project specification
