electric fine small seat regulating valve dual oriented structure, equipped with 3601L series electronic straight travel electric actuator. Has the advantages of compact structure, light weight, flexible action, valve capacity, flow characteristics of precision, convenient assembly and disassembly. Widely used in precise control of gas, liquid, steam and other media parameters such as pressure, the flow, temperature, liquid level maintained at a given value. Especially suitable for pressure, leakage is large and not very clean media occasions.
This series of products are the standard type, bellows seal type, jacket type insulation and other varieties. Nominal grade products are PN16, 40, 64; nominal diameter range of DN25~400. Apply the fluid temperature and various grades of -250 ℃ ~+560 ℃. The leakage of grade Ⅱ or Ⅳ standard. Flow characteristics such as linear or percentage. A variety of different specifications can be selected.
