ZDLP electric single-seat regulating valve, equipped with 3601L series electronic direct-stroke electric actuator, 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 such as pressure, flow, temperature and liquid level of gas, liquid, steam and other media. Keep at a given value. 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; the nominal diameter range DN25-400. The applicable fluid temperature ranges from - 250 C to + 560 C. The leakage standard is grade II or IV. Flow characteristics are linear or equal percentage. Various kinds of products are available. Species and specifications are available.
