The Difference Between Explosion-proof Electric Three-way Ball Valve And Explosion-proof Electric Hard-sealed Butterfly Valve

The three-way 4-sided valve seat ball valve with L-type flow channel adopts 2-sided valve seat. It is mainly used for flow path reversing.
The three-way 4-sided valve seat ball valve with T-type flow channel adopts 4-sided valve seat, which is balanced by force to ensure reliable sealing on the closed channel. It is mainly used for diversion, mixing, reversing and full opening of three channels.

As a component used to realize the on-off and flow control of pipeline systems, hard-sealed butterfly valves have been widely used in many fields such as petroleum, chemical industry, metallurgy, hydropower, etc. In the known butterfly valve technology, its sealing form mostly adopts a sealing structure, and the sealing material is rubber, polytetrafluoroethylene, etc. Due to the limitation of structural characteristics, it is not suitable for high temperature resistance, high pressure resistance, corrosion resistance, wear resistance and other industries. A relatively advanced butterfly valve is a three-eccentric metal hard-sealed butterfly valve, the valve body and the valve seat are connected components, and the valve seat sealing surface layer is welded with heat-resistant and corrosion-resistant alloy materials. The multi-layer soft stack seal ring is fixed on the valve plate. Compared with the traditional butterfly valve, this butterfly valve has the advantages of high temperature resistance, easy operation, no friction when opening and closing, and the seal is compensated as the torque of the transmission mechanism increases when closing, which improves the sealing performance of the butterfly valve and prolongs the service life.

The difference between 3 Piece Threaded Ball Valve and explosion-proof electric hard seal butterfly valve:

The explosion-proof electric three-way stainless steel ball valve is composed of an angular stroke series intelligent actuator and a three-way stainless steel ball valve. It is a rotary cut-off stainless steel gate valve. The electric three-way stainless steel ball valve has the advantages of precise closing, compact structure, light weight, and convenient maintenance. The electric three-way regulating stainless steel ball valve is widely used in the automatic control of pipelines of corrosive media such as gas, liquid, steam, and oil. The two-seat sealed electric three-way stainless steel ball valve has a compact structure, beautiful appearance, and good sealing performance.
Features of explosion-proof electric hard seal butterfly valve
1. The explosion-proof electric hard seal butterfly valve adopts a double eccentric structure, which has a sealing function that becomes tighter and tighter as it is closed, and has reliable sealing performance.
2. The sealing auxiliary material is a pair of stainless steel and nitrile oil-resistant rubber, which has a long service life.
3. The rubber sealing ring can be located on the valve body or on the butterfly plate, which can be used for media with different characteristics for users to choose.
4. The butterfly plate adopts a frame structure with high strength, large flow area and small flow resistance.
5. The overall paint can effectively prevent rust and can be used for different media as long as the sealing material of the sealing valve seat is replaced.
6. The explosion-proof electric hard-sealed butterfly valve has a two-way sealing function. It is not controlled by the flow direction of the medium during installation, nor is it affected by the spatial position. It can be installed in any direction.
7. The explosion-proof electric hard-sealed butterfly valve has a unique structure, flexible operation, labor-saving and convenient.
