Big size butterfly valve Supplier DN100-DN3600 Double Offset Butterfly Valve/Di Bi-Directional Sealing Eccentric Butterfly Valve

         

Product Description
TWT valve company can made the the  size from DN100-DN3600
flange double eccentric butterfly valve 
and  TWT valve company is the birthplace of china's first butterfly valve 
Double eccentric butterfly valve is unique structural design
Design of eccentric structure, the butterfly valve seat and the valve plate outer contour unique, effectively reduce operating torque, while reducing and the valve seat contact, improve sealing reliability. No mechanical internal DB type butterfly valve (fasteners) connection, no mechanical connection failure may, high reliability, the eccentric butterfly valve can adapt to the harsh working conditions. Filling epoxy resin process makes the valve plate and valve seat the contact surface with the same amount of interference, the elimination of machining and assembly errors, compared to the pressure evenly, reduce operating torque, reduce the abrasion of the sealing surface. DC type butterfly valve type N stainless steel ring is inlaid on the valve body, long can prevent corrosion, and can prevent the velocity of flow instability caused by the vibration and fastening the resulting parts loosening and shedding caused by the valve failure.
Big Size Butterfly Valve Supplier DN100-DN3600 Double Offset Butterfly Valve/Di Bi-Directional Sealing Eccentric Butterfly Valve

Sealing design of eccentric butterfly valve 
the eccentric butterfly valve use of high-quality stainless steel stem, is completely covered by the O ring and the bearing, corrosion resistance. Self lubricating bearings, sleeve type shaft seat valve used on the valve stem to stem bearing support, from the rotary friction minimum.
