KSB Double Flap Check Valve SERIE 2000 DN350 PN16 Compact, Impact-free and Durable Backflow Control for High Flow Lines

The KSB SERIE 2000 Double Flap Check Valve is a high-performance backflow prevention valve specifically designed for high-volume pipelines with a diameter of 350 mm (DN350). Its compact wafer-type design saves installation space, and its nickel-plated double flap provides a long-lasting, low-maintenance solution. Resistant to pressures up to 16 bar, this valve protects against water hammer without compromising flow performance. Supplied with the assurance of ORFA Industrial Products Industry and Trade Inc., this product can be used safely with a wide variety of fluids, including water, steam, and process fluids.

Product Working Principle:

The KSB SERIE 2000 check valve operates with two spring-supported flap mechanisms. The flaps, which open under fluid pressure, quickly close under spring force when reverse pressure occurs, preventing backflow. This reduces the risk of water hammer (water hammer) in the system and ensures installation safety.
