6223 Proportional Valve with Control Electronics

Brand: Burkert Fluid Control Systems

The valve, Type 6223, can be used to control the flow of large amounts of liquids. Low hysteresis, high repeatability and good response sensitivity guarantee good positioning behavior. The valve closes tight. The push-over coil is easy to replace.

Features: 
  • Control valve for continuous control of liquids
  • Low hysteresis and high repeatability
  • Control with PWM signal
  • Servo-assisted, tight closing valve
