KZDLN electric precision small double seat regulating valve
Overview of KZDLN electric precision small double seat regulating valve:
Product details
KZDLN electric precision small double seat regulating valvesummary:
The KZDLN electric precision small double seat regulating valve adopts a dual guide structure and is equipped with a 3601L series electronic linear 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 process parameters such as pressure, flow rate, temperature, and liquid level of gases, liquids, steam, and other media to maintain them at given values Especially suitable for media with large pressure differences, large allowable leakage, and not very clean environments
This series of products includes various types such as standard type, corrugated pipe sealing type, jacket insulation type, etc The nominal pressure rating of the product includes PN16, 40, and 64; The nominal diameter range is DN25~400. It is suitable for fluid temperatures ranging 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
