Product Overview
The VTOZ MA-DLHZO-LES-PS-040-L33/U1/32/S1/37 is a high-performance proportional directional control valve engineered for precise, infinitely variable control of hydraulic flow direction and magnitude in demanding industrial systems. Manufactured by VTOZ, this valve utilizes a precision-machined spool and sleeve assembly actuated by a high-response proportional solenoid, enabling smooth, stepless regulation of actuator speed and position. Unlike on/off directional valves, the MA-DLHZO-LES-PS series delivers proportional metering characteristics that bridge the gap between conventional directional control and full servo performance, making it ideal for applications requiring accurate motion control without the cost and complexity of a complete servo system. The integrated L33 spool configuration and U1/32/S1/37 electrical interface ensure compatibility with standard proportional amplifier cards and closed-loop control architectures.
