Neles has further developed the flanged ball valve series of MBV. The new X-Series is particularly designed to fulfill the requirements of chemical, petrochemical and refining industries. The proven special shaft/ball connection enables X-Series to be used in the most demanding high cycling applications, and also assures tight shut-off even with the lowest pressure differentials. The wide material and seat selection of X-Series makes it possible to choose the most suitable combination according to customers' specifications.
