1、Ultra-Short Compact Structure: The wafer design results in a face-to-face length much shorter than traditional flanged check valves, significantly saving space and reducing system weight.
2、Optimized Lift Guidance: The disc is equipped with a precision guidance device for smooth movement, preventing misalignment or jamming under high-velocity fluid impact.
3、Silent & Anti-Water Hammer: The built-in high-performance spring assists in pre-closing the disc before backflow occurs, significantly reducing noise and system water hammer impact.
4、Long-Life Sealing Surface: The sealing surfaces of the seat and disc are hard-faced or precision-lapped to resist erosion and corrosion, ensuring tightness over long periods.
5、Installation Flexibility: Its compact design allows for installation in horizontal lines or vertical lines with an upward flow direction.
6、Low Pressure Drop: The flow path is hydrodynamically designed to allow full disc opening, ensuring minimum pressure drop during high-flow conditions.
