retz The main components of imported electric high-pressure ball valves have been forged by professional manufacturers, overcoming the potential defects of cast steel valves and maintaining their structural compressive uniformity under maximum working pressure. Applicable media: Non corrosive media such as water, oil, gas, and acid alkali corrosive media
功能介绍 Function introduction
进口电动高压球阀是由锻钢高压阀体及电子式角行程电动执行器组成。电动执行器采用一体式结构，输入220V电源即可直接进行开关量调节，亦可内置伺服模块，输入控制信号(4～20mADC或1～5VDC)及单相电源即可控制运转 retz The electric high-pressure ball valve is composed of forged steel high-pressure valve body and electronic angular stroke electric actuator. The electric actuator adopts an integrated structure. It can directly adjust the switching value by inputting 220V power supply. It can also be equipped with a servo module. It can control the operation by inputting control signal (4~20mADC or 1~5VDC) and single-phase power supply
