MOOG D634-341C R40KO2M0NSS2
The MOOG D634-341C R40KO2M0NSS2 is a high-performance direct drive servo-proportional valve from the D634 series, designed for demanding hydraulic control applications. It features integrated digital electronics, providing precise 4-way directional control with excellent dynamic response, accuracy, and reliability. The innovative direct drive design utilizes a permanent magnet torque motor to directly actuate the spool, eliminating the need for a pilot stage. This results in very fast response times, high resistance to contamination, and enhanced operational efficiency. The R40KO2M0NSS2 variant is specifically configured for a nominal flow rate of 40 l/min, featuring an analog control interface, a zero-overlap spool for precise flow metering, and a center failsafe position upon power loss.
