97-21200W 98-21200W bellows seal control valve

Overview

97-21200W 98-21200W bellows seal control valve is composed of 21200W series bellows seal control valve and The 98 pneumatic diaphragm multi-spring actuator is composed. The 21200W bellows seal control valve is a new generation of bellows-sealed valve products developed successfully after years of testing and use after absorbing the advanced technology of domestic and foreign bellows sealing valves on the basis of the 21200 single-seat valve.

Feature

97-21200W 98-21200W bellows seal control valve maintains the characteristics of the 21200 series single seat valve such as good stability, small leakage, and wide range of use. The valve core part adopts a bellows seal structure, which is combined with the packing seal to form a double seal type, which can reliably prevent the process medium from flowing from the packing. The letter leaked out.

Therefore, it is especially suitable for controlling highly toxic, valuable, volatile and radioactive media.
