1) Small size, light weight, compact structure and easy maintenance. 2) The valve plate adopts a dual type, which can be quickly closed by itself under the elastic moment of the spring. 3) Due to the quick closing effect, the backflow of the medium can be prevented. 4) The valve body structure has small length and dimension, good rigidity, safety and reliability. 5) To achieve complete sealing, the leakage of hydraulic test is zero. 6) Easy to install, can be used for horizontal and vertical installation.
Overview
The H77X type wafer check valve produced by our factory is composed of valve body, valve disc, valve stem and spring and other parts, and adopts wafer connection. Water hammer is significantly reduced due to the short closing stroke of the disc and it is spring loaded. The valve is mainly suitable for urban, industrial and high-rise building water supply and drainage network. Because its structural length is shorter than that of general check valves, it is most suitable for places with limited installation space.
