Burkert Solenoid control valves
The 2871 Direct Acting Solenoid Valve is used as a control unit in control loops.
Burkert type 2873 is a direct acting 2/2 directional proportional (modulating) solenoid valve used as a regulator in control loops.
Burkert type 8605 is a signal converter for controlling proportional solenoid valves in the 40-2000 mA range.
Burkert control solenoid valves are proportional devices with an electromagnetic or electromotive drive.
Proportional units operate by electric actuators. Solenoid or motor acts as the actuator.
Burkert produces two types of control valves:
- General purpose
- Motor driven
General-purpose valves control flow rates of both liquids and gases. Versions with large or small coil are available. The housing is made of brass or stainless steel and has an IP65 enclosure rating. Such devices have a ramp function, current control, and Zero point shut-off.
Motor-driven valves category consists of two series: Type 3280 and 3285. Devices have an actuator that is fully isolated from the main stream. An integrated electric stepper motor acts as such actuator. Presented valves are available in three variants: standard, with positioner and process controller version. A high-pressure version up to 22 bar is also available.
The company reduced friction and stick-slop effects due to innovative technologies. All devices of this type are normally closed.
Control solenoid valves by Burkert primarily have fast response time, excellent sensitivity and repeatability of results.
