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.

Pneumatic Operated: The pneumatic operated adopts double piston rack structure, precise meshing, high efficiency and outputting constant torque. The cylinder body is made of extruded aluminum alloy with high strength and hardness. The sliding bearing is made of low friction materials, low friction coefficient, flexible rotation and long service life.

The design of shaft is blow-off resistant: The no-pin butterfly valve is designed with anti blow-off structure, and pneumatic operated can be changed under pressure.
