Kofloc

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

The rotational motion of the flow control screw is changed into a linear motion to ensure smooth flow control without causing a screw gap.

  • The completely clean inside of the valve permits clean flow control.
  • Special grease is used for the section not in contact with liquid to ensure outstanding durability.
