GENERAL
ZMAM/ZMBM Pneumatic diaphragm sleeve control valve has adopted sleeve-guided, pressure balanced double sealing surface and single sealing surface structure. The valve structure is co***ct .Liquid pipe appears S-streamline pattern which supply big flow coefficient, wider adjustable range and more exact flow characteristic. The control valve matched a multi-spring diaphragm actuator structure .It¡¯s widely used for good dynamic stability, low noise, high /low temperature and high differential pressure liquid situation.
