Overview

Agent Burkert Proportional Control Valve 8802 Germany * Our company is a professional enterprise engaged in fluid matching systems. We can provide selection, installation, and debugging services for Baode proportional control valves. German Burkert proportional control valves come in both pneumatic and electric versions, with electric ones generally suitable for industrial control with smaller diameters. Pneumatic proportional control valves can be used to regulate gases or liquids. It can be used for voltage stabilization, current stabilization, and temperature control.

Burkert proportional control valveWorking Principle:

Pneumatic control valve is a type of valve that uses compressed air as its power source, a cylinder as its actuator, and accessories such as electrical valve positioners, converters, solenoid valves, and holding valves to drive the valve, achieving on/off or proportional regulation. It receives control signals from industrial automation control systems to adjust various process parameters such as flow rate, pressure, and temperature of pipeline media. The characteristics of pneumatic control valves are simple control, fast response, and inherent safety, without the need for additional explosion-proof measures.

Burkert proportional control valveInstallation and Debugging

Installation key points
- Flow direction identificationEnsure that the fluid direction is consistent with the valve body arrow (to avoid sealing failure caused by reverse installation).
- vertical installationPrioritize the installation method where the valve core is perpendicular to the ground to reduce particle deposition (such as in sewage scenarios).
- Pipeline dampingIn situations with high vibration (such as pump outlet), flexible joints or shock-absorbing brackets need to be installed.
Debugging steps
- Zero point and range calibrationSet the input signal range through the controller or HMI interface (e.g. 4 mA corresponds to 0% opening, 20 mA corresponds to 100% opening).
- Dead zone adjustmentOptimize control sensitivity (such as reducing dead zone from ± 0.5% to ± 0.2%) to reduce steady-state errors.
- Response curve testingInput a step signal (such as jumping from 10% to 90%), record the valve response time and overshoot, and adjust the PID parameters if necessary.
Common troubleshooting
- Valve shakingCheck if the input signal is stable (such as signal fluctuations caused by electromagnetic interference), or adjust the PID parameters (increase integration time).
- Leakage exceeding the standardReplace the sealing components (such as worn PTFE valve seats), or check if the valve body is deformed (requiring return to the factory for repair).
- Drive overheatingReduce the ambient temperature or improve ventilation conditions, or check for overload operation (such as frequent start stop).
