This Australian Technical Specification sets out requirements for metallic and plastics-bodied valves that are actuated by way of an electric solenoid valve and intended to be installed in the water service. The valves are generally in a range of sizes up to DN 50 and for continuous operating temperatures not exceeding 80 degrees Celsius. Solenoid valves are used as a shut-off device for water supply and as prime components in sensor-activated urinal systems, electronic tap ware and the like.
