Kofloc Model 2600S/2600PVC Constant Flow Valve for Liquid

Description

The Kofloc Model 2600S/2600PVC Constant Flow Valve for Liquid operates as a mechanical flow regulator that automatically compensates for pressure differentials. In many liquid delivery systems, flow rates often drift as pump pressures shift or tank levels drop. This valve utilizes an internal diaphragm-spring mechanism to maintain a constant pressure drop across a precision orifice, resulting in an ultra-stable output.

The 2600S variant is constructed from SUS316 Stainless Steel, offering superior mechanical strength and high-pressure durability for general industrial liquids. For applications involving aggressive chemicals or deionized water where metallic contact must be avoided, the 2600PVC variant provides excellent corrosion resistance. The Kofloc Model 2600S/2600PVC Constant Flow Valve for Liquid is designed with a “set and forget” philosophy, providing maintenance-free operation and high repeatability for critical industrial processes.

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.
