Application: controlling and regulating cooling circuits

Your challenge: reliably regulating the coolant in semiconductor manufacturing

The solution from Festo:

  • Valve terminals VTUG and VTOC (1) for reliably controlling pneumatic media valves
  • Valve terminal type CPX-MPA, if additional I/Os are required, for example to control electric valves, integrate sensors or create closed-loop control circuits. With this terminal, diagnostics and remote maintenance functions can also be carried out.
  • Pneumatically or electrically actuated valves type VZXA, VZQA and VZWF (3) control the media flow. Very cold and/or hot media are reliably and accurately regulated, even in closed-loop control circuits.
  • The quarter turn actuator DFPD (4) actuates ball valves VZBF (5) and butterfly valves that are typically used in main lines and feed/discharge lines for cooling or temperature control media thanks to their high flow rate performance.
  • Sensor types SFAW (2) and SPAW (6) measure the flow rate as well as the temperature and pressure of the media extremely accurately.

Products for the semiconductor industry

Festo has a broad product portfolio for machines used in the manufacture of electronic components: the valve terminal VTOC with integrated safety function or our proportional pressure regulators VEAA/VEAB for pilot control of media valves which are typically used to control or regulate process gases.
