แบรนด์ : TOKYO KEISO



  • Cost effective flow control system
  • Space saving;
    • Flow sensor and control valve are integrated. This saves piping space.
    • DIN 24 x 48 size Controller saves panel space.
  • Full open/close type valve is adopted, and can be used as Shut-off valve which has been indispensable.
  • Drain out of line fluid by air purging possible
  • Lead-free solder has become reality.
  • High reliability of electronics
  • EMC Compatible standard: EN61326-1
