3.Product advantages

The structure is simple and compact, the rotation of 90 °is quickly to open and close, and the service life is long. The side flange can meet the PN10, PN16, 150Lb and 10K flanges;

All products can provide the pressure test: All Arnos products can provide the pressure test report before leaving the factory.

High performance seat rubber: The rubber content is 50%, and the switch life is more than 10000 times

Axial seal: The shaft is supported by 4 oil-free bearings, with double seal structure design, smaller torque and reliable seal;

Surface coating: Epoxy powder coating is adopted, with strong adhesion and good weather resistance. It can be used indoors and outdoors.

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.
