0718802100000013 Oil Control Valve OEM feedback Control System for Sany Concrete Pump

Product Description:

1. Valve characteristics: The characteristics of the control valve refer to the relationship between the valve opening and the fluid flow rate. Common valve characteristics include linear characteristics, equal percentage characteristics and fast opening characteristics. The linear characteristic means that the opening of the valve is linear with the flow rate, the equal percentage characteristic means that the opening of the valve is proportional to the percentage change of the flow rate, and the fast opening characteristic means that the valve has a large flow change within the initial opening range.

2. Valve adjustment mode: The control valve can be operated by different adjustment modes. Common adjustment methods include manual adjustment, automatic adjustment and intelligent adjustment. Manual adjustment requires manual intervention by rotating the hand wheel or operating lever to adjust the valve opening. Automatic adjustment Using sensors and feedback control system, automatic adjustment of valve opening according to preset parameters. Intelligent regulation uses advanced control algorithms and communication technology to achieve centralized control and optimal regulation of multiple valves.

3. Valve positioner: The valve positioner is a device used to detect and control the opening of the valve. It can be used in combination with the actuator to provide an accurate open feedback signal and to achieve precise valve regulation by controlling the movement of the actuator. Valve positioners typically use position sensors and electronic control units for high accuracy and stability
