DC1620W Bellows sealing control valve

DC1620W Bellows sealing control valve Introduction

DC1620W    The series of bellows sealed regulating valves is based on the existing medium and low pressure series regulating valves, adding a bellows sealing structure to ensure the original structural characteristics of the medium and low pressure series regulating valves. The valve cover adopts a bellows sealing structure, which can completely eliminate the possibility of medium leakage from the valve stem movement gap. Therefore, this series of products has been widely used in control systems for highly toxic, highly corrosive, volatile, highly permeable media and rare and valuable media.
