This type of regulating valve is widely used in flow and pressure control circuits in industries such as petroleum, chemical, power, and metallurgy, enabling precise regulation of the medium and ensuring stable operation of the production process.

1. Actuator (Blue Top Component)
This is the pneumatic diaphragm actuator. It uses changes in compressed air pressure to push a diaphragm, which in turn moves the valve stem. It provides the power for the valve's regulating action and features fast response and high control precision.

2. Valve Positioner (Device with Instrument on the Left)
This is an intelligent valve positioner that converts the electrical signals from the control system into pneumatic signals, precisely controlling the actuator's movement. It also has a feedback function, allowing real-time monitoring of the valve opening to ensure regulation accuracy. The pressure gauge on top displays the input and output air pressure for easy debugging and monitoring.

3. Valve Body (Lower Silver Component)
This is the single-seat valve body, featuring a straight-through flow channel design with an internal valve core and seat mating structure. The medium flows in from one side, passes through the gap between the valve core and the valve seat, and flows out from the other side. The flow rate is adjusted by changing the size of the gap through the up and down movement of the valve core.
