The story
The company was founded in 1949 in Brisbane, Australia, as a small tool shop. In the 1950s it developed a number of industry firsts: reduction valves, relief valves, pressure vacuum relief valves, pressure reducing and non-return valves. In 1953, RMC unveiled the world's first packaged unvented water heating storage system. By combining pressure reducing and relief valves into a pre-assembled unit, RMC Full Control Valves removed the need for ventilation pipes and ceiling cistern tanks, all but eliminating faulty installations and associated dangers. In 1986, Reliance Machinery Company was acquired by GSA Industries Group, an Australian private investment company. Business continued to grow through ongoing product development. In 2000, RWC acquired Yorkshire Fittings along with its brass plumbing and heating range, York Flex. In 2005, GAS and Ryemetal (a major supplier) amalgamated to form Reliance WorldWide Corporation (Aust). At the same time, the new RWC entered the US market with the acquisition of Cash Acme, the world's largest volume temperature and pressure valve manufacturer. RWC started promoting its name as Reliance Worldwide Corporation at the AHR Expo in the US, to reflect its growing global reach. In 2016 RWC became a publicly listed company on the Australian Securities Exchange and reorganised into three geographical regions –Americas; Asia-Pacific; and Europe, Middle East & Africa.
