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;
5. Surface coating: Epoxy powder coating is adopted, with strong adhesion and good weather resistance. It can be used indoors and outdoors.
6. Ductile iron handle: The handle is made of ductile iron, compared with Stamping handle, ductile iron handle is more better strength, stronger corrosion resistance and much more durable. The end handle with half-round structure design, is no edges and corners and feels very good.
