The Koenig Check Valves® feature a ball-style, one-piece, self-contained design for quick and precise flow control, and can be used to maintain system pressure and prevent backflow. They are available in both forward-flow and reverse-flow models in a range of standard size diameters, cracking pressures, and flow rates. The product line features suitability for high-volume production applications that require fast assembly. They don’t require thread machining, do not generate debris, and prevent contamination during installation. The metal-to-metal design requires no additional sealants or threads.
