Regardless of pressure fluctuations, the Kates I/Q valve will control the flow rate proportional to the 4 - 20 mA input. Flow output is perfectly linear to signal input. By internally controlling the differential pressure across an adjustable orifice, flow control is maintained to within 1-1/2% of setpoint.
Each valve is custom built to customer specifications and application requirements. The I/Q valve is shipped completely assembled and tested and requires no field calibration. It is provided with flow data for field personnel to tune their instruments to the I/Q output. The valve is flow tested at 33 different operating settings to ensure the accuracy of the system.
