The SZDLN electronic electric straight through double seat regulating valve adopts a dual guide structure and is equipped with a 9610L series electronic straight stroke electric actuator. It has the advantages of compact structure, light weight, sensitive action, large valve capacity, precise flow characteristics, and easy disassembly and assembly. Widely used for precise control of gas, liquid, steam and other media to maintain process parameters such as pressure, flow rate, temperature, and liquid level at given values. Especially suitable for media with large pressure differences, large allowable leakage, and not very clean environments.
There are various types of SZDLN electronic electric straight through double seat regulating valves, including standard type, bellows sealed type, jacket insulated type, etc. The nominal pressure rating of the product includes PN16, 40, and 64; The nominal diameter range is DN25-400. The applicable fluid temperature ranges from -250 ℃ to+560 ℃ in various grades. The leakage standard is level II or level IV. The flow characteristics are linear or equal percentage. A variety of varieties and specifications are available for selection.
