Advantages and Characteristics
High precision linear control:
Adopting force feedback proportional electromagnet+precision valve core structure, the linearity of pneumatic hydraulic conversion is ≥ 99%, and the output pressure/flow rate is strictly proportional to the pneumatic signal, which is suitable for motion control of precision machining equipment.
Built in displacement sensor (accuracy ± 0.01mm), real-time feedback of valve core position, eliminating hysteresis error (≤ 0.5%) through PID closed-loop control.
Fast dynamic response:
The valve core adopts a lightweight design (mass ≤ 200g), combined with a short damping hole flow channel (length ≤ 5mm), and a step response rise time ≤ 15ms, meeting the dynamic working conditions of high-speed stamping machinery, injection molding machines, etc.
Optimize the volume of the pneumatic control chamber to below 15cm ³, with a pressure signal transmission delay of ≤ 3ms, suitable for remote control scenarios.
Wide working condition adaptability:
Temperature resistance range -40 ℃~+80 ℃, can still maintain a response time of ≤ 30ms in a low temperature environment of -20 ℃;
Anti vibration performance up to 50Hz, 50g acceleration (compliant with ISO 16750 standard), suitable for bumpy working conditions of construction machinery.
