Product Overview
Our Dual‑Active Proportional Two‑Way Cartridge Valve** is high‑end poppet‑type screw‑in hydraulic logic element developed for modern high‑performance hydraulic systems Following ISO7368 / DIN24342 / GB2877 installation standards, this proportional cartridge valve delivers precise bi‑directional flow regulation under high‑pressure, large‑flow working conditions
As an upgraded variant of the standard two‑way cartridge valve, the dual‑active proportional cartridge adopts closed‑loop spool position feedback (LVDT), achieving accurate proportional throttling, fast response and low hysteresis. It is widely integrated into custom hydraulic manifold blocks, replacing traditional proportional spool valves for compact hydraulic power unit solutions in heavy‑duty industrial and mobile hydraulics.
Working Principle
Control the flow according to the signal. Provide the suitable drive electricity to the proportional servo-valve through the amplifier to control the movement of the main spool. The dis placement sensor of the main spool feedback signal to calibrate the amount of valve opening, so that it can correspond to the amplifier input signal.
