2/2 Proportional Flow Valve - 2871 Series

Burkert proportional solenoid valves provide continuously adjustable and smooth control over the flow of fluid passing through them. Unlike conventional solenoid and process valves which offer only On or off control, Burkert 2871 series process valves use PWM (pulse width modulation) to give you the ability to adjust the flow from 0 to 100 percent. Design features such as the frictionless installation of the valve plunger, for exceptionally accurate adjustment and the tight sealing elastomeric seat make this the ideal valve for demanding and high accuracy control.

Features and Benefits

• Direct acting operation
• Available in either brass or stainless steel
• Excellent response time
• Globe valve operating principle
• IP65 Rating
• Plunger valve actuator
• <15 ms response time
• 5 W power consumption
• 1500Hz PWM frequency
• 100% continuously rated duty cycle
• Repeatability of less than 0.25% of full scale
• Less than 5% hysteresis


PWM solenoid control valves are suitable for applications which require more control over the flow of fluid than the simple on/off offered by standard solenoid valves.

Two-way Valves and Control Modules

Valves and control modules designed specifically to operate together, provide a valve opening which is proportional to the input signal and allows this to be correlated to the respective operating conditions.
