Burkert Proportional Solenoid Valve 239091, 2 port(s) , NC, 24 V dc, 1/2in / 1258520

2/2 Proportional Flow Valve - 2875 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 2875series 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.
