The KELOR K105 Single Plate Wafer Check Valve is designed for reliability, efficiency, and simplicity. With a spring-assisted single disc mechanism, the valve opens easily under forward flow and closes instantly when the flow reverses — preventing backflow and ensuring safe operation of the system.

The K105 model features a robust, space-saving wafer body, constructed from high-quality materials to deliver durability and corrosion resistance. The soft-seat or metal-seat options provide excellent sealing capability for a wide range of media. Its slim profile fits between standard flanges, making installation fast and economical.

Ideal for HVAC systems, water treatment plants, power generation, and process industries, this valve meets industry standards for performance and reliability.
