1. Opening and Closing: When the instrument valve needs to be opened, the operating mechanism moves the valve core to the open position, allowing the fluid medium to flow smoothly. Conversely, when the instrument valve needs to be closed, the valve core is moved to the closed position, blocking the flow of the fluid medium.
2. Flow Regulation: Another important function of the instrument valve is to regulate the flow rate of the fluid medium. By adjusting the position of the valve core, the size of the fluid passage can be changed, thereby achieving precise flow control.
