                  [Essential information]  
                          The pneumatic film single seat control valve adopts a top guiding structure, the valve body is compact, the fluid channel is S streamlined, the pressure loss is small, the flow flux is large, the range of adjustment is wide, and the flow characteristic precision is high. Part of the spool oriented oriented area, has the characteristics of strong resistance to vibration performance, the seat closed performance of the GB/ 4213-92 standard, the valve is equipped with multi spring diaphragm actuator has the advantages of small structure, large output force, more suitable for the high temperature performance of the closed on demand and reliability, low temperature and pressure valve before and after the occasion use.
