Description

This Bürkert proportional control valve is designed for position control. The valve is open-loop controlled and there is no position feedback. A 0-10 V input signal must be used for the set-point value.

The 2-way valve has G 1 inch female threads and an internal orifice of 25 mm. This results in a Kv-value of 9.6 m3/h (Cv value 11.0976 GPM). Use our Kv-calculator to determine the optimal Kv-value for your pressure and flow rate.

The Bürkert 3285 valve has two oxide ceramic discs that both have an opening. By sliding one disc over the other, the degree of overlap of the holes can be varied and thus the opening of the valve. The disc 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 6 bar (0 to 87 psi). The housing is made of stainless steel and it has oxide ceramics/EPDM sealing. 

The valve takes 4 seconds to go from fully open to fully closed position. The flow goes above 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
  • Housing resistant to corossive and aggressive media thanks to the stainless steel design
  • LED display indicates the position of the valve

Cons:

  • Sensitive to dirt, so a filter should be applied upstream (≤ 0.3 mm)

3285 series

The Burkert series 3285 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. The valve uses a ceramic disc to change the size of the orifice which are available in sizes from 8 to 25 mm. There are two discs, one acts as valve’s seat and doesn’t move, while the other rotates and changes the orifice diameter. 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 3285 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.
