BUTTERFLY VALVE
Triple-Offset Butterfly Valve
Design Feature
SUNGO MT series butterfly valve is triple off-set design which has a advantage of light weight, compact design and cost effective and low operation torque and can replace traditional gate, globe & ball valve in most of industries application,! nclude the following design features:
structure of Triple-Offset:
Best Closing Angle
The closing angle “∝” is the seat tangent and the valve plate when the valve plate approaches the closing position the angle, the optimal closing angle can not only eliminate the opening and closing valve. The disc lag is also conducive to reducing the opening and closing moment.
Close-off and two-way sealing:
The laminated or solid valve seat ring is installed by the pressure ring on the valve plate between the sealing ring and the valve plate through the winding gasket. The contact surface between the valve seat and the sealing ring is the structure of the inclined cone, which produces the block effect under the closing torque, and makes the sealing ring produce elastic deformation, thus forming a tight two-way shut-off.
Optional sealing system:
