Product Overview
▔▔The Vickers KBHDG5V Series represents a high-performance range of two-stage, pilot-operated proportional directional valves. Known for their "plug-and-play" installation, these valves feature On-Board Electronics (OBE) where the control amplifier is directly integrated onto the valve body.
Key Advantages
▔▔-
Integrated Amplifier (OBE): Factory-set adjustments for gain, deadband compensation, and offset eliminate the need for user tuning on-site.
Closed-Loop Precision: Equiped with a high-accuracy Linear Variable Differential Transformer (LVDT) for main spool position feedback, ensuring exceptional reproducibility and low hysteresis.
Rugged Durability: Protected by a robust metal enclosure rated at IP65/IP67 against moisture and ingress, and fully certified for high-vibration environments.

FAQ
▔▔Q1: What is the main difference between KBHDG5V and standard KBDG5V valves?
The primary difference is that KBHDG5V includes On-Board Electronics (OBE) with an integrated amplifier and spool-position feedback (LVDT). The standard KBDG5V does not have integrated electronics or direct spool feedback and requires an external amplifier card.
Q2: What input signals do these valves accept?
They are designed to accept standard industrial analog control inputs: either a voltage command of ±10V or a current command of 4-20 mA (depending on the specific model code suffix, such as M1 or M2).
