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

  • Outstanding control of liquid flows at a constant rate
    A valve composed of high-precision components ensures smooth control of flows.
  • Not affected by pressure variations
    Flows are maintained at a constant rate against fluctuations of both primary and secondary pressures.
  • Non-metal material (PTFE) used for the wetted part
    This resin (PTFE) is perfect for a part apt to be easily damaged by metal ions.
  • Small flows from 100-500 ml/min controllable
    Minute flows are also controllable optionally.
  • Model 2600, all-Teflon type, is compatible with practically all chemicals thanks to the use of a Perfluoro O-ring.
    (There are some operating conditions to be met according to the type of chemical. Be sure to contact us for information before placing your purchase order.)
  • Bubblers (air bubble purge taps) provided in the upper/lower diaphragm chambers
    Air bubble purge at the initial flow setting stage of operation provides the most accurate possible control.

Applications

  • Ultrapure water analyzers
  • Environmental instrumentation systems; food/chemical industry equipment
  • Ultrapure water and chemical mixing systems
