Manual butterfly

Butterfly valve structure is simple, small size, light weight, only by a few parts. And just rotate 90 ° to quickly open and close, easy to operate, while the fluid control valve has good features. Butterfly valve is fully open position, the disc thickness is only when the medium flows through the body resistance, produced by the valve pressure drop is small, it has a better flow control characteristics. Butterfly valve sealing elastic sealing and two metal seal type. Elastic sealing valves, seals can be mounted on the body or attached to the disc periphery.

Why cast stainless steel butterfly has a magnetic?

Stainless butterfly valve to reduce the magnetic key is to control the content of martensite or ferrite, the smaller the less magnetic, or make their organizational structure fracture distribution. Pipe, sheet metal is heated billet through many times, extrusion, cooling and other technology out, this process has been interrupted martensite points system, the organizational structure of ferrite, but it is very evenly distributed, so the pipe, small magnetic plates or feel.

The rise of ceramic butterfly valve

With the development of infrastructure, construction and implementation of national investment in large-scale projects, so that the number of electric power, petroleum, chemical, urban water supply, drainage systems, more and more butterfly valves, especially the amount is quite large relative to the widespread use of metal valves, new ceramic materials are widely used, making the ceramic control corrosion, high temperature, wear resistance, erosion, has a significant breakthrough anti-magnetic and anti- static, etc., more able to adapt to the harsh conditions of the work environment.
