The KOFLOC RK4400 has been designed specially for connection to precision pressure regulators, and is widely used for cylinder regulators.

Features

The precision needle valve Model 2412 is used for easy, fine adjustment of flow.
The flow meter tube made by high-precision molding ensures
excellent stability and repeatability even if it is inclined.
The material, cleaning method, and assembly are carefully designed
for the use of high-purity, high-price standard gases so
as to eliminate waste losses, reduce absorption of constituent
gas and minimize generation of other types of gas from the parts.
