Product Description:
Triple Eccentric Electric Butterfly Valve
Description:
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.
