Product Details
Electric vacuum butterfly valve
Vacuum butterfly valve is widely used in power generation, oil, gas (natural gas), chemical industry, smelting, environmental protection and other projects in the vacuum system to transport a variety of corrosive, non-corrosive fluid medium, used to regulate and cut off the flow of media, and maintain a certain degree of vacuum.
1. Compact structure, easy to assemble, disassemble and repair;
2. The operating torque is small, the flow resistance is small, and the energy saving effect is good;
3. Reliable sealing, zero leakage, long opening and closing life;
4, the unique vacuum valve structure design, the use of double seat structure, the valve installation without direction requirements, and between the two valve seats and valve shaft packing can be filled with pressure water, increased sealing 14 can, can be two-way seal, the valve vacuum has been greatly improved.
5. It can be designed and manufactured with different materials according to different grades, different working conditions and different temperatures to meet the requirements of different users.
