Product Overview
The Rexroth LC32DB20E74 (Material Number: R900912543) is a high-performance 2-way cartridge valve engineered for pressure control functions within demanding industrial hydraulic systems. Manufactured by Bosch Rexroth, a global leader in drive and control technology, this valve is part of the proven LC series of logic cartridge valves. It operates on a two-stage, pressure-controlled principle, utilizing a pilot-operated poppet design to regulate system pressure with exceptional accuracy and repeatability. As a pressure control valve, it functions as a pilot-operated relief cartridge, capable of managing high flow rates while maintaining precise pressure settings. Its robust construction and leak-free seating design make it a critical component for system safety, overload protection, and pressure regulation in complex hydraulic circuits.
