ZDLN electric compact double seat valve adopts double guide structure and 3601L series electronic direct stroke electric actuator. It has the advantages of compact structure, light weight, sensitive action, large valve capacity, accurate flow characteristics and easy disassembly and assembly. It is widely used to accurately control the process parameters such as gas, liquid, steam and other medium such as pressure. The force, flow rate, temperature and liquid level are kept at a given value. It is especially suitable for large pressure difference and large leakage volume, and is not very clean medium. This series of products includes standard type, bellows seal type, jacket insulation type and so on. The nominal pressure level of products is PN16, 40 and 64, and the nominal diameter range is DN25~400. The suitable fluid temperature is -250 grade ~+560 temperature range. The leakage standard is grade II or IV. The flow characteristics are linear or equal percentage. Various varieties and specifications can be selected. Main parts material Valve body, valve cover: HT200, ZG230~450, ZG1Cr18Ni9Ti Valve core and valve seat: 1Cr18Ni9Ti, titanium alloy surfacing. Fillers: polytetrafluoroethylene, flexible graphite and stainless steel bellows. Gasket: Rubber asbestos plate, 1cr18Ni9Ti, graphite wound gasket. Stem and push rod: 2Cr13, 1Cr18Ni9Ti Bushing: 2Cr13 |
