3、Product Advantages
  • (1)The structure is simple and compact, the rotation of 90 °is quickly to open and close, and the service life is long.
  • (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
  • (4)Axial seal: The shaft is supported by 4 oil-free bearings, 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.
  • (5)Surface coating: Epoxy powder coating is adopted, with strong adhesion and good weather resistance. It can be used indoors and outdoors.
  • (6)The design of shaft is blow-off resistant: The no-pin butterfly valve is designed with anti blow-off structure, and electric actuator can be changed under pressure.
