Our advantage fully welded ball valve,automatic recirculation valve supplier - Edvc Valve

Ball valve is defined as a valve whose opening and closing parts (ball) are driven by the valve stem and rotate around the axis of the ball valve. It can also be used for fluid regulation and control. Among them, there is a strong shear force between the V-shaped ball core of hard sealed V-shaped ball valve and the metal valve seat of surfacing cemented carbide. It is especially suitable for media containing fiber and micro solid particles. The multi-way ball valve can not only flexibly control the confluence, diversion and flow direction switching of media on the pipeline, but also close any channel to connect the other two channels. This kind of valve shall be installed horizontally in the pipeline. Ball valve classification: pneumatic ball valve, electric ball valve and manual ball valve.
characteristic
1; wear-resisting
Because the valve core of hard sealed ball valve is alloy steel spray welding and the sealing ring of three piece ball valve is alloy steel surfacing, the hard sealed ball valve will not produce too much wear when opening and closing. (its hardness coefficient is 65-70):
II; Good sealing performance
As the sealing of hard sealed ball valve is manually ground, it can not be used until the valve core is completely consistent with the sealing ring. So its sealing performance is reliable.
III; Switch light
Because the bottom of the sealing ring of the hard sealed ball valve adopts a spring to hold the sealing ring tightly with the valve core, the switch is very light when the external force exceeds the preload of the spring.
IV; Long service life
It has been widely used in petroleum, chemical industry, power generation, papermaking, atomic energy, aviation, rocket and other departments, as well as people's daily life.
