Dereve's roots go a long way back into British manufacturing history. Evered Limited, was a very large manufacturing Company originally established in 1803.
Out of Evered in 1977 Dereve was established (Evered spelled backwards!), when Evered sold off its Pressure Reducer Section of its Controls Division.
Initially, Dereve's primary focus was the production of water governors and pressure reducers, but steadily we have expanded our range of products, including developing our own range of relief valves.
