Sentronic-D 608/609 Series Proportional Valve
for high dynamic response three direct acting proportional valves for standard and mid-range technical solutions with adjustable parameters.
Typical application of proportional valve
1. Power control
•Cylinder converts air pressure into thrust/thrust
Gas pressure control can realize Force control
•Requirements: – Direct-acting electro-proportional valves are usually required to achieve high dynamic and precise control - Repeated pressure adjustments are easy to cause wear topiloted proportional valves
Constant 2, pressure control
• Constant air pressure output for constant voltage or airflow
•Constant air pressure, flow rate changes•Requirements: – The air pressurecan be fine-tuned and the pressure stability is high
Dynamic positioning Open loop positioning: Resilience air pressure balance
Control djerk means line actuator position
Requirements: – Requires direct action proportional valve, provides highly dynamic control characteristics – cascade control with external sensors
flow control
•Vath coil diameter, and pressure converted to gas flow control.
• Flow control can be achieved by regulating pressure, usually with Used for gas purge or cooling process control
•Requirements: – stable pressure output and high dynamic response in a wide pressure range – large power requirements, can be used with an external power amplification module (Booster)
