CV-300B Swing Check Valve – Heavy-Duty Backflow Prevention Valve
The CV-300B Swing Check Valve is a reliable automatic check valve designed to control one-way flow and prevent reverse flow in water, fire protection, and industrial piping systems. Featuring a robust swing disc design, the valve provides dependable operation without external power or manual adjustment.
Built with a durable cast iron or ductile iron body and corrosion-resistant internal components, the CV-300B is engineered for long-lasting performance in demanding environments. The hinged disc mechanism allows smooth flow passage while automatically closing when reverse flow conditions occur, helping protect pumps, pipelines, and connected equipment.
Available in multiple sizes and configurations, the CV-300B can be supplied with suitable connection options depending on system requirements. The valve is commonly used in fire protection networks, water distribution systems, commercial plumbing, and industrial applications where reliable backflow prevention is required.
