The natural environment is preserved through the balance of solids, liquids and gases that exist on the earth. However, human civilization has caused pollution that has greatly damaged our environment. The task of the present generation is to restore our environment to its natural healthy state. And this is also the greatest challenge for 21st century science and technology.

KOFLOC’s corporate motto is “A Scientific Approach for Fluids.” In other words, we create products that scientifically measure and control the balance of liquids and gases. We trust that through our work we are making a contribution to the regeneration of the environment and to the establishment of a prosperous society.

Features

  • High accuracy and high response are achieved by the flow sen-sor with temperature-following current difference detection.
  • A normally-closed solenoid valve is employed.
  • A low leak rate is achieved by the weldless structure and metalseal.
  • The dead volume is reduced thanks to the diaphragm seat valve.
  • The face-to-face and body dimensions and the wiring tie-inpoints are designed to facilitate replacement of devices made by other companies.
