The Burkert proportional solenoid valve 2833, upgraded to model 2873, is a direct-acting Burkert proportional solenoid valve suitable for process control and also applicable to process vacuum. It features low hysteresis, good repeatability, high sensitivity, and excellent regulating performance.
Its resilient seat seal provides a tight-closing function and ensures high safety.
The Burkert 8605 controller converts the analog input signal into a PWM (Pulse Width Modulation) signal, which then controls the operation of the 2833 Burkert valve.
The 8605 Burkert controller also features the following functions: ● Temperature compensation for coil heating via internal current regulation ● Convenient zero and range setting ● Rise time function reduces rapid state changes.
Two-position two-way Burkert proportional solenoid valve characteristics: ● High sensitivity ● 0-16 bar 1) ● DN0.8-4mm ● G 1/8”, 1/4” or base plate connection ● Optional EEx explosion-proof Burkert proportional solenoid valves 2833 and 2873.

upgraded to model 2873.
Overview of Burkert proportional solenoid valves: Based on the on/off solenoid valve that closes upon de-energization via spring action, Burkert proportional solenoid valves achieve a balance between spring force and electromagnetic force from the coil current by modifying the structure of the electromagnetic components.
The valve spool stroke and/or valve opening are determined by the magnitude of the coil current and/or electromagnetic force. The valve opening is directly proportional to the electromagnetic force.
German Burkert proportional solenoid valves are controlled by pulse width modulation (PWM) signals, which cause the coil current to vary according to a set value.
Because both the medium pressure and the electromagnetic force overcome the spring force, a controller can be used to set minimum and maximum flow rates under operating conditions. German Burkert proportional solenoid valves can be used to implement both 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 set value and the actual value.
Key characteristics of the Burkert 2873 proportional solenoid valve's positioning performance: ● Hysteresis: The largest difference in output signal when the input signal changes from small to large and from large to small, expressed as a percentage of the large output signal.
● Response Sensitivity: The smallest difference in setpoint value that causes a change in output signal, expressed as a percentage of ● Repeatability: The largest deviation in output signal. when the same input signal of the same magnitude is applied repeatedly in the same direction.
● Control Ratio: The ratio of Kv values at large and small openings (see calculation for proportional valves). Burkert proportional solenoid valves can achieve a control ratio of up to 1.500.
Plain language sourcing guide for Burkert proportional solenoid valve 2833 upgraded to model 2873
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.
