Description
This Bürkert proportional control valve is designed for position control. The valve is open-loop controlled and there is no position feedback. A 4-20 mA input signal must be used for the set-point value.
The 2-way valve has G 3/8 inch female threads and an internal orifice of 4 mm. This results in a Kv-value of 0.5 m3/h (Cv value 0.578 GPM). Use our Kv-calculator to determine the optimal Kv-value for your pressure and flow rate.
The angular movement of the motor is converted to translational movement with the aid of a threaded spindle which is rigidly connected to the valve’s spindle. The valve spindle is connected to a control cone which affects the size of the orifice. Elastomer seal is connected directly to the control cone so the media flows under the seat and doesn’t come in contact with the actuator. The globe valve's position is actuated by a stepper motor and holds a position with minimal power loss. This makes this valve highly energy efficient.
The valve is electrically operated with a 24 V DC supply voltage. The electrical connection on the actuator is an 8-pin male M12 plug.
It can be used for media temperatures from 0 to 70°C (32 to 158°F) at a pressure of 0 to 15 bar (0 to 217.5 psi). The housing is made of brass and it has EPDM sealing.
The valve takes 2.5 seconds to go from fully open to fully closed position. The flow goes below the seat. They are suitable for control of clean media that doesn’t react with the housing and seal materials. The environment temperature ranges from -10 to 60°C. Please consult the instruction manual to find the proper duty cycle within the temperature range.
Pros:
- Fast response time
- The actuator features an energy-saving function
- LED display indicates the position of the valve
Cons:
- Sensitive to dirt, so a filter should be applied upstream (≤ 0.3 mm)
3280 series
The Burkert series 3280 is designed for controlling the flow rate of liquid and gaseous media. Only clean, liquid or gaseous medium, which does not react with the bodies and sealing materials, may be controlled. These motorised globe valves are ideal for proportional flow control with orifices ranging from 2 to 10 mm. The angular movement of the motor is converted to translational movement with the aid of a threaded spindle which is rigidly connected to the valve’s spindle. The valve spindle is connected to a control cone which affects the size of the orifice. Elastomer seal is connected directly to the control cone so the media flows under the seat and doesn’t come in contact with the actuator. These are suitable for operating pressure ranging from 0 to 6 bar (0 to 87 psi) and media temperature ranging from 0 to 70 °C (32 to 158 °F). Type 3280 is available as a standard ON/OFF or proportional valve, as a version with integrated positioner and as a version with integrated process controller. These control valves are available in stainless steel and brass design.
