Wafer type swing check valve

BFLON Lined Valves is a reputable manufacturer of Lined Wafer Type Swing Check Valves, producing world-class corrosion resistant backflow prevention for critical and non-critical industrial applications. With over 25 years of experience in industrial pipeline valve design and manufacture, process engineering, process design, and design, erection and commissioning, BFLON can help you select the right application based on specific requirements. Our quality and safety standards are unparalleled to all others, and are verified and certified with our ISO 9001, ISO 14001, and OHSAS 45001 certification. We guarantee valve quality, safety and environmental sustainability for all applications globally, anytime and anywhere.

The BFLON Lined Wafer Type Swing Check Valve allows flow to move in a forward direction only and automatically, if the downstream pressure is at a lower pressure than the upstream pressure; and it prevents a reverse flow and stops potential damage to pumps, compressors and process. The wafer type styles are compact, and the entire valve is fully lined with the highest quality PTFE which provides complete chemical resistance to all wetted parts, and protects all wetted parts from aggressive acids, alkaline substances and solvents. The design of the valve utilises a swing disc to minimise energy loss, and low pressure loss and smooth low resistance flow can be achieved, and can therefore be used continuously.

Key advantages include high corrosion protectiveness, assures a seal, will require little maintenance and is easy to install between standard flanges of pipelines. Because of the wafer design and its lightweight material, it naturally saves space, making it ideal for pipeline dimensions that require compact dimensions.

Applications include chemical and petrochemical plants; pharmaceuticals; water and wastewater treatment; and food and beverage processing. Choosing BFLON as an Lined Wafer Type Swing Check Valve manufacturer means securing a solution that is strong, efficient and reliable check valve for needs of backflow prevention.
