Electronic type electric staight signle, double seat control valves
features
ZYHP, ZYHN type electronic type electric straight single-seat regulator and electronic straight two-seat regulator use double oriented structure, equipped with 3601L series electronic straight travel electric actuators. With compact structure, light weight, quick action, high accuracy of flow characteristics, convenient in assembling and disassembling etc. It is widely used for precise control gases, liquids, steam and other medium parameters, such as pressure, temperature, flow rate and fluid in a given value. Especially suitable for bigger pressure difference, allowing leakage is also larger and not very clean medium. Electronic type electric straight signle, double seat regulator has standard type, bellows sealing type, jacket insulation and other types. Shanghai Yihuan flow control equipment Co., LTD. produced electronic type straight single-seat regulator and electronic straight double seat nominal pressure are PN16, 40, 64, nominal diameter scope is DN25-400. The applicable temperature range is -120 degree – 450 degree range of different grades. Leakage standard is class Ⅱ or class IV. Flow characteristic is linear or equal percentage. Various specifications are available. This product performance index implements GB/T4213-92
