The KBCG3L160DZM12APE7H110 proportional pressure relief valve is manufactured by Vickers and belongs to the Directional Control Valves series. Designed for hydraulic automation, it regulates system pressure in response to an analog reference. The valve receives a ±10 V command input and uses a 24 V DC supply voltage to power its internal circuits. On-board electronics interpret the command signal and drive the spool accordingly. Electrical connection is accomplished through a 7-pin connector with plug, while the hydraulic interface follows ISO 4401-03 (NFPA D03/CETOP 3) dimensions for easy manifold installation. The body mounts on a subplate, and its ramp type is standard for predictable pressure transitions. During operation the valve can control pressure up to 160 bar.
The model is built with left-hand orientation to match assemblies that standardize on that port layout. It withstands a maximum operating pressure of 350 bar and passes a peak flow of 5.0 L/min without exceeding rated limits. Proper function requires system fluid cleanliness at ISO code 17/15/12 or better to protect internal clearances. Viton seals are fitted to resist hydraulic oil and elevated temperatures within the specified range. Acceptable ambient and fluid temperatures extend from −20 °C to 70 °C, ensuring service in most industrial environments. These characteristics combine to deliver stable pressure relief performance in compact manifolds where precise electronic modulation and reliable sealing are mandatory.
