The CA111972-11/6FT application field and its working principle can be divided into two main categories: Flow Control and Pressure Control.

As a Flow Control device, CA111972-11/6FT uses its mechanical flow gate to police and control the flow rate of the medium inside the pipeline. Generally, for Flow Control application, the CA111972-11/6FT is installed in a monolithic way, meaning, the air and the fluid flow through the same pipeline segment. The pressure difference between the two flanges, or the differential pressure, will determine the flow rate of the medium. The CA111972-11/6FT can automatically adjust its gates to change the opening area of the gate, and thereby adjusts the flow rate as required.

As a Pressure Control device, the CA111972-11/6FT uses the same gate as the Flow Control application, however, it is connected in a twin flow branch line. The upper branch is a pressure controlled outlet branch, and the lower branch is a variable flow outlet branch. The pressure difference between the two branches will control the flow rate of the medium from the lower branch. Thanks to the CA111972-11/6FT, an automatically adjustable pressure regulator, it can establish equilibrium automatically and regulate the distribution control valve in a stable condition.

In terms of working principle, the internal mechanism of the CA111972-11/6FT comprises three parts: a spool valve, a diaphragm and a balanced plug. The spool valve is controlled by the pressure difference between the two pipelines, enabling it to fill or empty the space between the valve and the diaphragm. As the volume of air inside the valve increase, the diaphragm expands, pushing the balanced plug outwards, resulting in the closure or reduction of the area of the valve opening. When the pressure inside the valve is decreased, the diaphragm contracts and the valve opens.

The CA111972-11/6FT is thus a compact and versatile combination of flow and pressure control capabilities that can adapt to many applications. It can be used for applications such as air-conditioning units, chilled water distribution systems, and cold storage rooms. The reliable performance and pressure control accuracy of the CA111972-11/6FT make it a popular choice for many industrial and domestic applications.
