Series LR digital servo proportional valve

Digital Precision Meets Compact Control

Explore the innovative Series LR digital proportional servo valves – engineered for precise flow, pressure, and position control in a compact, DIN-rail mountable design.

The Series LR digital proportional servo valves redefine precision in industrial automation with their innovative 3/3-way direct operation and integrated closed-loop control. Designed for flow (LRWD2), pressure (LRPD2), and position (LRXD2) regulation, these valves feature a patented rotating spool system that ensures minimal leakage, high reliability, and superior responsiveness.

Compact and efficient, the LR series integrates an onboard electronic board directly within the valve body, ready for immediate connection. The micro USB interface allows for seamless configuration via PC, adapting the valve's performance to a wide range of application requirements.

Built to mount easily on a DIN-rail, the Series LR valves are ideal for use in control cabinets where space and efficiency are paramount. Whether you need high precision in flow management or advanced position feedback, these valves offer exceptional linearity and hysteresis performance, especially in the pressure control version.
