The Burkert 8694 model Burkert positioner for process control valves, also known as a Burkert controller, is a typical digital electric positioner for Burkert process control valves. Top-mounted or side-mounted Burkert controllers are also called Burkert electric positioners.
These controllers control the valve opening and flow rate regulation ratio.
This Burkert valve positioner is widely used in biopharmaceuticals, food and beverage, and water treatment and environmental protection industries. The most commonly used Burkert positioner series are the 8692, 8693, and 8694 models.

Burkert Positioner 8694 Type Description - Burkert process control valves with integrated digital electric positioner. This compact Burkert positioner integrates with pneumatic process valves. Setpoints are remotely adjusted via a 4-20 mA signal or AS-interface. A non-contact analog signal position sensor detects the valve spindle position.
Simple installation via the automatic Tune function, and settings via DIP switches: shut-off function, characteristic curve selection, reverse working direction, manual/automatic mode switching, and binary input. The Burkert 8694 electric positioner utilizes a freely programmable characteristic curve, allowing for software and other interfaces.
The Burkert valve position is displayed via LED components. The Burkert controller can optionally integrate analog signal position feedback.
Features of the Burkert 8694 positioner: Compact and durable stainless steel design; easy commissioning via the automated Tune function; non-contact position sensor; positioners are key accessories installed on pneumatic control valves.
Based on their structure, valve positioners can be categorized into pneumatic valve positioners, electric valve positioners, and intelligent valve positioners.
The Burkert valve positioner receives the output signal from the controller and then uses its output signal to control the Burkert pneumatic control valve.
After the Burkert control valve actuates, the valve stem displacement is fed back to the Burkert valve positioner via a mechanical device, and the valve position status is transmitted to the upper-level system via an electrical signal.
The working principle of the Burkert valve positioner is to compare the valve stem displacement signal as the input feedback measurement signal with the controller output signal as the setpoint signal.
When there is a deviation, the output signal to the actuator is changed, causing the actuator to actuate, thus establishing a one-to-one correspondence between the valve stem displacement and the controller output signal.
Therefore, the Burkert valve positioner forms a feedback control system with valve stem displacement as the measurement signal and the controller output as the setpoint signal. The manipulated variable of this control system is the output signal from the Burkert valve positioner to the actuator.
The Burkert valve controller, also called a valve control box, is a product used in conjunction with an electric valve actuator to control the opening and closing of the Burkert electric control valve, enabling remote control of the electric valve from a control room.
Burkert valve controllers, when used with electric valve valves, are widely applied in industries such as water supply and drainage, heating power plants, manufacturing, food processing, textiles, papermaking, shipbuilding, steel, and coal.
The Burkert valve controller operates by using indicator lights to show the valve's status: open, closed, fully open, fully closed, fault, protection, local, and remote control.
Burkert electric valves trigger audible and visual alarms when there is excessive torque (fault) or motor overcurrent/overheating (protection), facilitating timely troubleshooting (depending on the electric actuator's functions, valve electric actuators from different manufacturers may not include motor overheat protection).

Plain language sourcing guide for Burkert positioner 8694 for process control valves
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.
