ZDLN electric precision and small two-seat regulating 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, convenient disassembly and assembly, etc. It is widely used to precisely control the process parameters of gas, liquid, steam and other media, such as pressure. Force, flow rate, temperature and liquid level are kept at a given value. It is especially suitable for medium with large pressure difference, large allowable leakage and not very clean.

    This series of products include standard type, bellows sealing type, jacket insulation type and other varieties. The nominal pressure grades of products are PN16, 40, 64, and the nominal diameter ranges from DN25 to 400. The applicable fluid temperature ranges from - 250 +560. The leakage standard is grade II or IV. Flow characteristics are linear or equal percentage. Various specifications are available.
