Australian Valve Group (AVG)
Project Description

AVG designs, manufactures, and distributes a range of heating and control valves for the world and for the Australian domestic, industrial and commercial plumbing industry.

AVG has built a number of automated test and calibration systems to support the manufacture of their valves. ICON Technologies developed the controller for the latest test system to be deployed by AVG, the TVA Calibration Machine, working in collaboration with AWN Electronics as the machine electrical and mechanical designer.

The TVA Calibration Machine is used to calibrate the “out-of-box” valve position that delivers a mixed water stream at a rated temperature from separate hot and cold water flows, and to test the safety cut-off response to a loss of cold water flow, as per industry standards AS4032.1 and AS4032.2 for thermostatic mixing and tempering valves.

The system included a mix of analog voltage inputs, 24V digital I/O and relay outputs, to perform closed loop control on the valve position, to monitor and control water flows, pressures and temperatures as required, and to drive the hardware-based user interface.
