Product description
The pneumatic single-seat control valve adopts a top-guided structure, and the flow channel is S streamlined. It has the advantages of compact structure, sensitive action, small pressure drop loss, large valve capacity, accurate flow characteristics, convenient maintenance, etc., and can be used in harsh working conditions. It is especially suitable for working occasions with high leakage requirements and small pressure difference between the front and back of the valve.
