      ZMAW pneumatic membrane control butterfly valve / ZSRW, ZSCW pneumatic piston control butterfly valve input control signal (4-20mADC or 1-5VDC) air source can control operation, simple and compact structure, easy to manufacture large diameter, with self-cleaning effect, small resistance coefficient, large flow capacity. It is suitable for the regulation of suspended solids and strong and turbid slurry fluids. Clean medium, can choose the valve plate plus soft seal (rubber ring, tetrafluoro ring) to reduce leakage (up to 0.01%), high temperature and high pressure can choose the three eccentric hard seal valve body. The order must be marked.

      Note: This table is the limit service temperature of all kinds of materials. In actual selection, the lowest and highest service temperature of materials should be determined according to the medium temperature range of the products. The lowest service temperature should not be lower than the lower limit of the medium temperature range, and the highest service temperature should not be higher than the upper limit of the medium temperature range.
