（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 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.
（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.
