Product Overview
The Rexroth LT 06-A06-3X/150B40/02M (Material Number: R900427591) is a high-precision pilot control valve from the Rexroth LT series, engineered for reliable hydraulic pilot signal generation and directional control in demanding industrial systems. This valve operates on a proven spool-type directional principle, utilizing a manually or mechanically actuated spool to precisely meter and direct pilot oil flow to downstream main-stage directional valves, proportional valves, or servo valves. With a nominal size of 06 and a 3X series design, it delivers consistent actuation pressure and repeatable response characteristics essential for accurate hydraulic system control. The LT 06 series is widely recognized for its robust construction, low leakage characteristics, and long service life in continuous-duty industrial environments.
