Burkert Electric Proportional Valve | Burkert Electric Control Valve Model 3280 The Burkert 3280 electric control valve is a standard on/off type. In the ON/OFF type, the Burkert valve digitizes an external voltage signal and accordingly closes or opens the valve.
Burkert Control Valve The standard type of Burkert proportional valve converts an external standard signal, ie, the position rating, into the valve position. The two terminal positions of the Burkert valve are signaled via status LEDs.
Additionally, the valve position "Closed" is output via a digital output. Burkert Electric Control Valve Model 3280 On-Time Derating Curve On-time is an important factor in motorized valves. The limits self-heating of the motor the maximum on-time.
Higher ambient temperatures also increase the risk of damage due to overheating.
The following chart lists the recommended maximum on-time based on ambient temperature. In energy-saving mode (lower drive force), a longer on-time may be possible. The Burkert valve function of the motor has been optimized for size, power consumption, and cost.
The turn-on time refers to the motor's turn-on time, not the device's.
The 3280 electric proportional valve can only be opened when it Frequent changes to the ratings will significantly increase the motor's turn-on time. Note: Operating the 3280 electric control valve beyond the recommended limits for turn-on time may significantly reduce the valve's lifespan.
Burkert Electric Proportional Valve | Burkert Electric Control Valve 3280 Type.
There are two types of controllers: Burkert Electric Control Valve 3280 Type - Position Controller Type. In the position controller type, the proportional valve converts an external standard signal, ie, the position rating, into the valve position. The position of the drive unit is adjusted according to the position rating.
The current position (POS) of the electric valve is detected by a displacement sensor. The position controller compares this actual position value with the rating value (CMD) of the standard signal.
If a regulation difference (Xd1) exists, a motor control signal is sent to the control drive unit as the regulation amount. signaled via status LEDs. Additionally, the actual position value obtained by the displacement sensor is output via circular connector M12.
The Burkert electric control valve model 3280 – process controller type – allows for process control within a cascaded control range, in addition to adjusting the actual position value, through an additionally operated PID controller. The process controller is integrated into the control loop.
The position rating is calculated from the process rating and the actual process value using the control parameters (PID controller). The process rating can be specified via an external signal. During process control, the aforementioned position adjustment is subordinate to the auxiliary control loop; thus, cascaded control is achieved.
The process controller in the main control loop has PID functionality. The process rating (SP) is specified as the rating and compared with the actual value (PV) of the process quantity to be controlled. The displacement sensor measures the current position (POS) of the electric actuator.
The position controller compares this actual position value with the process controller's rating (CMD). If a control difference (Xd2) exists, the actual position (POS) and valve opening are changed via the control amount (CTRL). Z2 represents the interference level.
Plain language sourcing guide for Burkert Electric Proportional Valve | Burkert Electric Control Valve Model 3280
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.
