Name: valve actuatorFunction: control valve switch by controlling air flow sizeIntended classification commodity code: 8412310090 (other linear acting pneumatic power unit, pressure cylinder)Shanghai Pudong Airport customs change classification: 84123900 (other pneumatic power unit)Commodity code information given by China Customs official network: 8412310090 (actuator, valve parts, valve actuation, pneumatic)Our goods encoding 8412310090 is classified to the Shanghai Pudong Airport customs dismissed, there are no friends of this commodity encoding on the official website of the detailed specifications defined, I Secretary in accordance with the valve function into 8412310090 encoding. Thank you
The boring actuator, that is, the pneumatic valve actuator, is described in the customs notesPneumatic valve actuator (three) separately presented. This device is equipped with a piston metal enclosure, linear motion of compressed gas generated by a needle perpendicular to the piston rod into the rotary motion, in order to control plug valve or other device with a rotary deviceSo the Shanghai customs will bring you the list backIn fact, the most important point of distinction or the actuator is pneumatic energy conversion in what form movement of the mechanical energy output, if it is a straight reciprocating, 84123100 is correct, if not belonging to the rotary linear motion, or radians, 841239 correct

Various types of valves, with the continuous improvement of various types of equipment, process, the types of valves are still increasing. But generally speaking, they can be divided into two major groups.(1) automatic valve. A valve that moves by itself depending on the capacity of a medium (liquid, air, steam, etc.). Such as safety valve, pressure reducing valve, check valve, steam trap, air trap, emergency shut-off valve and so on. (2) drive valve. A valve operated by hand, power, hydraulic, or pneumatic. Such as gate valve, globe valve, throttle valve, regulating valve, butterfly valve, ball valve, plug valve and so on.
