Product Name: Triple Eccentric Electric Butterfly Valve

Product introduction:
Triple Eccentric Electric Butterfly Valve is with the structure of tri-eccentric conical oblique cutting which sets the center line of flange and the center line of the valve body at an Angle so that the disc leave the sealing surface away from the valve seat sealing surface immediately when open and in the closing moment will touch and press on the valve seat sealing surface.

The sealing ring is superimposed by stainless steel and graphite composite plate which can stand the temp. up to 540℃.
It is a device to regulate and cut off the medium of those piping in petroleum chemical power metallurgy and city heat supply system.
