Product Description

 Product Advantages

1. The structure is simple and compact, the rotation of 90 °is quickly to open and close.
2. All products can provide the pressure test: All CHAOJI products can provide the pressure test report before leaving the factory.
3. High performance seat rubber: The rubber content is 50%, and the switch life is more than 30000 times. The rubber and valve body are joined by vulcanization process, and the joint is tight and doesn't fall off;
4. Axial seal: The valve shaft has a double seal structure design of oil seal and O-ring, smaller torque and reliable seal; The upper and lower shaft holes of DN350 and above large diameter valves are designed with packing box structure, and the packing is pressed by the gland to realize sealing.
