Burkert 2875 solenoid proportional valve - China's official distributor. Popular Burkert proportional valve models sourced directly from the German factory: Burkert 2875 proportional valve 00255726 4mm, Burkert 2875 proportional valve 00236922 8mm, Burkert 2875 proportional valve 00299908 2mm (base plate connection), Burkert 8605 controller 00178354 (upgrade model 316530).
Overview of Burkert Solenoid Proportional Valves: Burkert proportional solenoid valves are based on the on/off solenoid valve where a spring closes when power is off.
By modifying the structure of the electromagnetic components in the on/off Burkert solenoid valve, the spring force and the electromagnetic force of the current coil are balanced.
The valve stroke and/or valve opening are determined by the magnitude of the coil current and/or electromagnetic force. to implement open-loop and closed-loop control loops.
Open-loop loops do not require actual value feedback, while closed-loop control loops adjust based on the deviation between the setpoint and the actual value. Burkert proportional solenoid valves can be controlled using either the Burkert 8605 controller or the Burkert 8611 universal controller.
In principle, the 8605 Burkert controller converts the analog setpoint signal at the input into a corresponding pulse-width modulated signal output, which is used to control the Burkert The Burkert 2875 solenoid proportional valve, available from the authorized distributor in China, is a Burkert proportional solenoid valve.
Furthermore, the 8605 Burkert controller features current regulation to compensate for coil heating, adaptability of small and large coil currents to the applied pressure conditions, zero-point cutoff, and ramp functionality. To ensure optimal control functionality, the selection of the Burkert proportional valve must be based on its intended use.
Important selection parameters are the Kv value and pressure range.
The Kv value (unit: m²/h) for Burkert valves is measured with water as the medium, at 20°C, an inlet pressure of 1 bar, and an outlet pressure of 0 bar. For gases, it is usually expressed as the QNn value. The proportional solenoid valve selection guide.
QNn value is the flow rate (l/min) of air at 20°C, an inlet pressure of 6 bar, and a pressure drop of 1 bar.
The reference conditions for gas are an absolute pressure of 1.013 bar and a temperature of 0°C. Besides the Kv value, the maximum pre-pressure at the valve inlet is also a major factor in valve selection (model and nominal diameter).
The smaller the valve nominal diameter or the larger the coil, the higher the maximum opening and closing pressure.
The Kv value can be calculated using the following formula. Based on the calculated Kv value and the actual pressure range, the valve model can be found in the Burkert solenoid proportional valve selection guide.

Plain language sourcing guide for Burkert 2875 Solenoid Proportional Valve
Start with the full model name. Check the brand name. Check the part number. Check the code on the old unit. These small checks help you avoid a wrong order.
Take one clear photo of the front label. Take one photo of the side label. If the part has a cable, plug, port, seal, coil, or screen, take a photo of that area too.
Tell us the quantity you need. Tell us your country. Tell us the date when the plant needs the part. We can then check stock, lead time, safe packing, and the best shipping plan.
If the exact model is no longer made, do not guess. Send the old model and the use case. LEHIY can compare close options and explain which choice is safer for repair work.
Use simple order notes. Write the model in one line. Write the quantity in one line. Write the delivery country in one line. This helps our team reply faster.
Check the old part before removal. Look at the label. Look at the connector. Look at the mounting size. Look at the voltage or pressure rating if it is shown.
Do not rely on a short nickname for a part. Many industrial items have close versions. A small suffix can change the plug, output, range, or software setting.
Ask for a stock check if the plant is stopped. Ask for a lead time if the order is planned. Ask for packing photos if the part is fragile or heavy.
For a replacement order, tell us what failed. Tell us where the part is used. Tell us if an equal model is acceptable. This makes the first answer more useful.
For repeat orders, send the last invoice, old label, or old packing photo. The same reference can help us match the correct product again.
For urgent service, keep the message simple. One model, one quantity, one photo, and one delivery target are enough for a fast first check.
