The structure and function of Globe Valve

With the needs of industrial development, the Globe Valve appeared later than the pneumatic Control Valve, but its scope of use is becoming more and more extensive. Because it does not require an air source, it is more convenient to install and use. It can work as long as the power supply and control signal are connected. The following editor will introduce the structure and function of the Globe Valve.

The typical shape of a Globe Valve, which consists of two detachable actuator and regulating valve (regulating mechanism) parts. The upper part is the actuator, which accepts the 0~10mADC or 4~20mADC signal output by the regulator, converts it into the corresponding linear displacement, drives the lower regulating valve to act, and directly regulates the flow of fluid. The actuators of various types of Globe Valve are basically the same, but the structure of the regulating valve (regulating mechanism) has many types due to different use conditions. The most commonly used ones are straight-through single valve seat and straight-through double valve seat.
The Globe Valve is an industrial on-site execution instrument composed of a regulating valve body and different electric actuators. It accepts the 4-20mA or pulse signal output by the regulator to perform closed-loop control to realize flow, pressure, temperature, liquid level, etc. Automatic control of parameters, and you can choose intelligent electric actuators to realize digital transmission with DCS, PLC, etc. to form a more intelligent control system. There are two power supply voltages for Globe Valve: 220V and 380V. The flow characteristics of Globe Valve, electric single-seat control valves, and electric small Flow Control Valves include equal percentage, linear, and fast.
