Kiwi valve claims better mix

Better temperature control is the claim of computerised industrial water-mixing valves developed in Auckland.

Better temperature control is the claim of computerised industrial water-mixing valves developed in Auckland. The Technology Development Group has found a way to fit controlling devices inside the valves, instead of outside. General manager Harold Forrest says this makes them more accurate, which cuts costs and allows better industrial network management. The valves combine a computer, electronics, sensors and a small motor. They are a spin-off from an electronic domestic shower valve that the company has designed and made, selling the rights to a US company. Selling for several thousands dollars, depending on their metal casting, Forrest hopes the firm can cash in on the $US850 million worldwide water-mixing valve market. The valves won't be officially launched until the International Sanitary & Heating Fair in Frankfurt next March, but already a New Zealand dairy company is using them. As well as industry, Forrest says the valves can be used in hospitals and apartment blocks. Technology New Zealand funding helped develop the valve.
