Overview:Company's sole purpose is to design, build, and market a patented compressed air flow controller.
Compressed air flow control is imperative to total system efficiency and reliability.
First, pneumatically-actuated positioners tend to fail because the pressurized air often carries with it moisture and contaminants, which interfere with the operation of the actuator. In certain cases, the moisture can even travel from the actuator through an electrical conduit down to the control panel, causing a short or other malfunction. Indeed, for compressed air systems that do not otherwise require a dryer, pneumatically-actuated positioners are unworkable, since the excess moisture will cause routine failure.
Second, these systems are prone to "hunting" or oscillation of the valve as its searches for the proper position to maintain set point pressure. "Hunting" results from a disparity between the relatively fast response time of the electronic means that are used to sample downstream pressure, and the relatively slow response time of the pneumatically-actuated positioner and valve.
Thus, there is a need for a flow controller that is not subject to failure resulting from contaminants in the pressurized air, and that is able to find and maintain the proper valve position without undue valve oscillation.
The solution: The Patented Electronic Flow Controller
