ZDLN electric fine small two-seat control valve adopts double guide structure, equipped with 3601L series of electronic straight trip electric actuator. With compact structure, light weight, sensitive action, large valve capacity, precise flow characteristics, easy disassembly and so on. Used in the precise control of gas, liquid, steam and other media parameters such as pressure, flow, temperature, liquid level maintained at a given value. Particularly suitable for large pressure, allowing leakage is also large and not very clean media occasions The
This series of products are standard, bellows sealed, jacket insulation, and other varieties. Product nominal pressure rating PN16,40,64; nominal diameter range DN25 ~ 400. Applicable fluid temperature range of -250 ℃ ~ + 560 ℃ within a variety of grades. The leakage standard is grade II or grade IV. Flow characteristics are linear or equal percentage. A wide variety of specifications are available.
