\"\" — Three eccentric metal hard seal butterfly valve
Butterfly valve has been widely used in many fields, such as petroleum, chemical, metallurgy, water and electricity, as a part to realize the on-off and flow control of pipeline system. In the known butterfly valve technology, the sealing form of sealing structure, sealing materials for rubber, ptfe and so on. Due to the limitation of structure characteristics, it is not suitable for high temperature, high pressure, corrosion resistance, wear resistance and other industries. There is a more advanced butterfly valve is three eccentric metal hard seal butterfly valve, valve body and valve seat are joined component, valve seat sealing surface layer surfacing welding temperature, corrosion resistant alloy material. Multi-layer soft stack sealing ring fixed on the valve plate, this butterfly valve compared with the traditional butterfly valve has high temperature resistance, light operation, opening and closing without friction, closed with the torque of the transmission mechanism to compensate for the sealing, improve the sealing performance of the butterfly valve and prolong the advantages of service life.

There is a more advanced butterfly valve is three eccentric metal hard seal butterfly valve, look at the valve body and seat are joined components, seat sealing surface layer surfacing welding temperature, corrosion resistant alloy material. Multi-layer soft stack sealing ring fixed on the valve plate, this butterfly valve compared with the traditional butterfly valve has high temperature resistance, light operation, opening and closing without friction, closed with the torque of the transmission mechanism to compensate for the sealing, improve the sealing performance of the butterfly valve and prolong the advantages of service life. However, the following problems still exist in the use of this butterfly valve:<\/a>

Mounted eccentric half ball valve
Eccentric ball valve using eccentric valve body, eccentric ball and valve seat, stem for rotary motion in the common trajectory of automatic centering, closing the process more and more tight, fully achieve the purpose of good sealing. Ball valve and valve seat completely separated, eliminate the wear of sealing ring, overcome the traditional ball seat and ball sealing surface always wear problem, non-metallic elastic materials are embedded in the metal seat, seat metal surface is well protected. This product is especially suitable for steel industry, aluminum, fiber, small solid particles, pulp, coal ash, petroleum gas and other media. <\/a><\/figcaption><\/figure>\n\n\n\n
Full bore hard sealing ball valve<\/h2>\n\n\n\n
Fixed ball valve, is a new generation of high-performance ball valve, suitable for long-distance transmission pipelines and general industrial pipelines, its strength, safety, resistance to harsh environment, etc. in the design of special consideration, suitable for all kinds of corrosive and non-corrosive media. Compared with the floating ball valve, it works, the fluid pressure in front of the sphere of all is passed to the bearing force, will not make a sphere to the seat to move, so the seat will not bear too much pressure, so the fixed ball valve torque is small, the seat of the small deformation, stable sealing performance, long service life,<\/figcaption><\/figure>\n\n\n\n
