Our brand story

The Reliance name in water control valves was born in 1949 with a passion to protect people and property. As the business grew, we developed many industry-leading innovations, including pressure reducing valves and the first low pressure relief valve, as well as the world’s first packaged unvented heating storage system that would go on to transform the industry. 

Fast forward to today and Reliance Valves is a global brand focusing on the design and manufacture of valves for the control of water pressure, temperature and flow, plus components for sealed heating systems. 

Our innovative spirit continues, with new products developed to make lives easier, safer and ever more reliable.
