ZMAX(Q) series pneumatic film three-way regulating valves adopt double spool up-down guiding structure with multi-spring actuator. The valve body is four-way structure, i.e. one-in-two-out (diversion type) and two-in-one-out (confluence type), so as to achieve the effect of mixing and cooling of fluids or diversion of fluids to meet the needs of different working conditions. Ask. The valve body has the advantages of compact structure, light inside, sensitive action, low pressure drop loss, high allowable pressure, large valve capacity, accurate flow characteristics and convenient maintenance. It can be used in various working conditions, especially for temperature control system of heat exchanger in petroleum industry and automatic control of other industries. The valve has many types, such as common combined (split) flow, high temperature combined (split) flow and so on. The nominal pressure classes of products are PN1.6, 4.0, 6.4; the nominal diameter range of valve body is DN25-400; the leakage classes are Class II and IV; and the flow characteristics are straight line and equal percentage. Various varieties and specifications are available.
