The Bosch Rexroth 3WRCE 50 V000P-2X/SG24K31/C5M-133 (R901166970) is a sophisticated high-response valve designed for precise control of fluid flow and direction within hydraulic systems. This valve is part of the WRCE series, known for their role in control loops where they are predominantly utilized. The construction consists of a stage pilot control valve equipped with a dry torque motor, a low-friction nozzle flapper system, an amplifier, and mechanical feedback for spool position monitoring. Additionally, it includes a main stage for regulating flow and an inductive position transducer that monitors the spool's movement. The functionality of the 3WRCE 50 V000P-2X/SG24K31/C5M-133 centers around its integrated or external electronics which compare command values to actual values, adjusting the torque motor's current to correct any deviation. The pilot control valve adjusts proportionally to manage the flow into the A and B control chambers, which in turn actuates the main spool within a closed-loop system up to the point of control deviation. It's important to note that flow rates are also influenced by pressure drops across the valve. Valve particularities include factory-set opening points for the V spool which can be readjusted if necessary via a zero-adjustment potentiometer after component replacements. In situations such as power failures, this valve is designed so that its pilot pressure connects to control chamber B, ensuring that P to A is closed or A to T is open depending on whether pilot pressure is applied. The main spool's default position under no pressure conditions ensures P to A closure due to an internal spring. This high-response valve features block installation design and integrated electronics (OBE), making it suitable for various applications including presses, die casting machines, and nibbling axes where precise position, pressure, force, and velocity controls are crucial. Its design ensures reliability even during power outages thanks to its trimmed pilot valve which maintains essential connections or closures as needed.
