We design and manufacture industry-leading hydronic products and solutions that give you control at every turn and help create energy-saving, cost-efficient HVAC installations.
Ensuring you have control at every turn is what we’re all about. We’ve developed a range of applications and software downloads to help you design, install and optimise every type of HVAC solution.
We are the Hydronic Engineering experts. We invented the concept, created products to back up the theory and love sharing best practice at our Hydronic College and through regular training seminars.
Download library We’ve created an extensive library of product-related technical documentation and a wide range of other useful information to help you get the most out of our globally-renowned products and solutions.

The female-threaded version is designed for connection to threaded pipe, or in conjunction with compression fittings, to copper precision steel or multi-layer pipe (only DN 15).
Articles – With Eclipse automatic flow limitation
For reversed flow direction
The thermostatic valve bodies for reversed flow direction can be used in two-pipe pump heating systems for interchangeable supply and return flow (hammering noises). The valve bodies can be mounted into the return flow connection of radiators in a raised position or tall radiators. This makes the thermostatic head more easily accessible.
