Bosch Rexroth 0811-402-511 Hydraulic Proportional Control Valve delivers precise, proportional control of hydraulic flow in response to an electrical input signal. Identified by part number 0811-402-511, this valve is part of Bosch Rexroth’s proportional valve lineup and is rated for up to 315 bar. In operation, it converts a control signal into a variable opening that modulates hydraulic flow to a downstream actuator, enabling smooth speed and position control rather than binary on/off actuation. This makes it suitable for hydraulic circuits that require accurate, repeatable proportional control of pressure and flow.
