Electric Triple Eccentric Butterfly Control Valve

Electric triple eccentric butterfly control valve is composed of electric actuator and metal seal (or soft seal) butterfly valve body, and an external electric valve positioner is used to input control signal (4-20mADC or 1-5VDC) air source to control operation and adjust the pressure of medium , flow and temperature. The product has compact structure, small resistance coefficient, large flow capacity and self-cleaning function. It is suitable for the adjustment of suspended particle fluids and turbid slurries.

Electric regulating butterfly valve is mainly divided into metal sealing regulating butterfly valve and rubber PTFE soft sealing regulating butterfly valve. The metal seal regulating butterfly valve adopts triple eccentric butterfly valve body, which is suitable for high temperature and high pressure conditions; the rubber PTFE soft sealing regulating butterfly valve adopts valve plate and soft seal (rubber ring, PTFE ring) to reduce leakage (zero leakage), Suitable for cleaning media.

Therefore, the electric triple eccentric butterfly control valve is widely used in metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas, drainage and other medium temperature ≤ 550 ℃ corrosive medium pipeline.

Main features 

1. The structure is simple, compact, light in weight, easy to install and disassemble, and easy to maintain;

2. The valve body adopts stainless steel elastic metal hard sealing structure, which has excellent sealing performance with the butterfly plate under high temperature and low temperature conditions;

3. There is almost no friction between the sealing ring and the butterfly plate, the service life is long, and the tighter the tighter the function;

4. The sealing surface of the butterfly plate of the electric regulating butterfly valve adopts surfacing welding cobalt-based hard alloy, the sealing surface is wear-resistant and has a long service life;

5. The electric triple eccentric butterfly control valve is easy to operate flexibly, you only need to rotate the valve stem 90° to complete the switch;

6. The valve body is resistant to high temperature, low temperature and corrosion, not affected by medium pressure, and has reliable sealing performance.
