Direct‑drive servo valve

This valve removes the hydraulic pilot‑stage. A linear force‑motor / voice‑coil motor drives the main spool directly. Built‑in LVDT sensor provides electrical closed‑loop, output flow follows input signal for precise cylinder position, velocity and force control.

Advantages: Strong contamination resistance; no pilot‑stage zero leakage; spring‑centered on power loss for safety; simple structure and good reliability.

Applications: Industrial test rigs, presses, metallurgy, injection molding and other closed‑loop hydraulics prioritizing reliability.
