Depending on their size – pipe diameters can vary from 1.9cm (3/4”) to 15cm (6”) – our valves contain between one and eight thermostatic elements.
Where more than one element is provided, a single failure – an incredibly unlikely event – will only result in a small change in operating temperature. Some of those elements are as follow:
Some elements like the 2001A, the 2012A or the 2040A are easy to replace. To maximise reliability, we recommend that O-ring seals and housing gaskets are replaced at the same time.
