The structure has no mechanical wear and scratch in the process of opening and closing, small closing torque, good cutting performance, and long service time, as well as two functions of adjustment and cutting.
This Pneumatic tri-eccentric hard seal butterfly valve is DN800, for air application, its function for cut-off air course. It is for one chemical industry in Southeast China.
The valve body is WCB, the pressure is DIN 0.6 Mpa, working temperature is -60 to 200 °C
The max size for Pneumatic tri-eccentric hard seal butterfly valve BCST can make is DN 2000.
If you have any special requirement, we can also make based on your detail.
