Description
The Kofloc Model 2204 Variable Primary Pressure Flow Controller is specifically built to solve the challenge of “unstable supply pressure.” In many industrial and laboratory environments, the inlet pressure can fluctuate due to shared gas lines or the natural pressure drop of a gas cylinder. The Model 2204 compensates for these variations automatically, ensuring that the mass flow remains consistent at the outlet.
This controller works by integrating a differential pressure regulator with a precision needle valve. As the primary pressure shifts, the internal diaphragm adjusts the internal valve opening to keep the differential pressure across the needle valve constant. Consequently, the Kofloc Model 2204 Variable Primary Pressure Flow Controller provides a level of stability that standard needle valves cannot match. Its compact, panel-mountable design makes it a favorite for analytical equipment manufacturers and pilot plant engineers who demand reliability without the complexity of electronic mass flow controllers.
