Kofloc Model 1500 Flow Meters and Controllers for Liquid

The Model RK1500 Series Flowmeter is equipped with a bellows seal type needle valve so that it can withstand high vacuum, high pressure, high temperature and toxic gases

Description

The Model RK1500 Series Flowmeter is equipped with a bellows seal type needle valve so that it can withstand high vacuum, high pressure, high temperature and toxic gases.

In order to respond to the new field, KOFLOC has been focus on liquid-related product. As a first step, we developed liquid mass flow controller [FCL-200] and ultrasonic flowmeter for various liquid [FML-500]. We will continuously try to increase our liquid-related lineup to respond to client’s demand, so please don’t hesitate to contact KOFLOC even if it does not meet your needs.

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 reliability against leak is ensured because 100% leak test is conducted before shipping, using a helium leak detector. Bellows seal type needle valve perfectly eliminates leak from the valve stem.
  • Superior corrosion resistance is ensured by using SUS 316,FKM, fluorocarbon resin and Pyrex glass only for wetted parts and those which are exposed to other fluids.
  • Enhanced stability and repeatability are ensured using a flow-meter consisting of a precision-formed try-flat, rib-guided glass tube and a ultra-precision ball float in combination with a so-phisticated needle valve.

Applications

  • For vacuum systems
  • For semiconductor manufacturing lines
