triple eccentric flange electric hard sealing butterfly valve china manufacturer

triple eccentric flange electric hard sealing butterfly valve china manufacturer    Product Description   The summarize of metal seal electric butterfly valve Hard seal electric butterfly valve metal seat triple eccentric electric butterfly valve sealing principle use the eccentric structure. Did it when the valve opens there is almost no frication phenomenon between the butterfly plate and seat .Stem torque through the butterfly plate directly transfer to seal face, thus eliminating the common jump phenomena when open the generic valve. This means that the eccentric butterfly valve can be almost from 0 at the opening into controlled area until the opening of 90. The normal control is more than 2times to the generally butterfly valve. Regulation population can be as high as 100:1 above which creating good conditions of the eccentric butterfly valve used as a control valve.  Product features  Metal seal can be used in particle,grout medium Applicable temperature can reached 425℃ Seal almost no friction, small torque, with perfect sealing Flange clamp holes connection apply to many kinds of standard Product parameter
