Kofloc RK1600R Purge Flowmeter with Needle Valve

Description

The Kofloc RK1600R is designed to meet the rigorous standards of industrial and laboratory purging. Its primary purpose is to maintain a constant, steady flow of fluid critical for protecting sensitive sensors, preventing line contamination, or maintaining stable inert atmospheres.

The “R” series designation signifies a refined glass tube manufacturing process that ensures superior linearity and repeatability. Unlike standard utility meters, the Kofloc RK1600R Purge Flowmeter with Needle Valve features a robust block-style body that minimizes the risk of leaks and structural stress. The needle valve is typically located at the inlet or outlet (depending on the specific configuration) to allow for precise manual control. Its compact footprint makes it perfect for high-density panel mounting, while the crystal-clear protective shield ensures maximum operator safety without compromising visibility.

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.
