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.

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.
