butterfly valve

The main body of the valve is welded structure. The Electric Louver Butterfly Valve disc is composed of several shutter discs which move around their respective rotating shafts. The shaft end is sealed with flexible graphite braided packing, which has the characteristics of high temperature resistance and self lubrication. The working principle of the valve is that the output torque of the driving device is transmitted to each valve shaft through the connecting rod mechanism, and the rotation of each valve shaft drives the rotation of their respective shutters to change the cross-sectional area of the pipeline, so as to achieve the function of cutting off the medium in a large area, reducing the medium pressure or regulating the medium flow, and the adjustment angle is 0-90 °. It has the advantages of simple structure, small flow resistance, light weight, flexible rotation, long service life and convenient operation and maintenance

The 10 inch butterfly valve is double eccentric structure allows reduced friction with seal ring and extended service life. The flanged butterfly valve is flexible operation, labor-saving, convenient, not affected by high and low ring pressure, reliable sealing performance. The flange butterfly valve can changing the disc seal ring,O ring,disc,stem and the packing,this kind of valve suitable for different medium. Easy to mount and dismantle convenient for servicing.

Large Diameter Big Size DN4600 Damper Butterfly Valve is welded with high-quality wear-resistant materials, with good wear resistance, stable and reliable operation, easy operation, sensitive action, small leakage rate, long service life and convenient installation and maintenance. It is especially suitable for low pressure difference, large diameter and large flow occasions. It is used in combination with various actuators to form different performance valves.

This welded ends butterfly valve design makes the valve an ideal hard seal butterfly valve for bubble sealing in high temperature, high pressure and fire protection applications. Due to the welding structure, without flange,and no need counter flange,the valve welded to pipe directly by welding rod，so finally the valve can achieve leakage in the pipeline. This valve has no flange, while saving costs and it is convenient and very beautiful for piping and thermal insulation.

Lug type ductile iron vition seat butterfly valve easy to install and operate, hot sale, widely application. Lug type ductile iron vition seat butterfly valve small in size and light in weight, can be mounted wherever needed.

Acid resistant SS304 butterfly valve, triple offset, worm gear and wheel to operate, body seal is welded SS or cobalt-based alloy, disc seal is 316 multi-layer assembly, which can anti-resistant. Acid resistant SS304 butterfly valve have long service life and can be used in petroleum, chemical, metallurgy, etc. corrisive condition.
