The kbs20305ns11ecoansvscns00110 proportional valve is built by Vickers in the Proportional Valves series. It modulates flow and pressure in hydraulic automation systems that require accurate electronic control. A coil rated at 24 V DC drives the spool, allowing direct connection to common machine power supplies. The ±10 V command input gives proportional displacement so controllers can scale motion without additional signal conditioning. For networked installations, CANopen communication permits parameter adjustment and status monitoring over a single bus. A 7-pin connector with a plug provides the electrical interface and shields the wiring from contamination. The body follows the ISO 4401-03 (NFPA D03) port pattern so it bolts to standard subplate manifolds, and the designated valve mount type is subplate to keep piping external to the block. The unit is configured as a single stage assembly with a P-blocked, ABT-connected spool to direct oil between actuator ports in neutral.

Compatibility with antiwear hydraulic oils enables the valve to operate in industrial power units without changing the fluid formulation. Viton seals maintain leakage control under hot oil conditions and resist chemical attack from additive packages. The maximum operating pressure is 350 bar, supporting high-force cylinders, while the tank port rating of 250 bar prevents backpressure damage on return lines. A rated flow of 40 L/min matches medium-size actuators and keeps pressure losses within design limits. The temperature envelope spans from −20 °C to 70 °C, allowing cold start-up and sustained service in warm environments. There is no manual override, so actuation depends exclusively on the solenoid and electronic command, which eliminates unintended shifts during maintenance. These characteristics round out the hydraulic performance profile and ensure the valve integrates reliably into closed-loop motion or pressure control schemes.
