Product Features
Direct-Acting DDV Design
No pilot stage, no pilot leakage, strong anti-contamination capability, dynamic response independent of oil supply pressure.
High-Precision Closed Loop
LVDT + built-in electronic amplifier provides low hysteresis, high repeatability, suitable for precision position/pressure/force control.
High Dynamics
Fast response and high frequency response, suitable for high dynamic systems.
Low Power Consumption
Extremely low current near zero position for energy saving operation.
Fail-Safe Operation
In case of power failure/signal loss, the valve core returns to spring neutral position, enhancing system safety.
Compact Structure
Single-stage, integrated electronics simplifies system design and installation.
Typical Applications
Injection Molding Machines
Die Casting Machines
Rubber Machinery
Material Testing Machines
High-Frequency Vibration Tables
Aviation Simulation
Flight Simulators
Metallurgical Equipment
Heavy-Duty Presses
Multi-Axis Synchronous Hydraulic Systems
