Introduction to Motorised Valves

Motorised valves control the flow of water between heating and hot water zones in domestic fully pumped central heating systems.

The MYSON range of Power Extra motorised valves has been designed with complete reliability and compatibility in mind. Our motorised valves are compatible as replacements to all leading makes, so you don’t need to look anywhere else.

The range has low contact resistance switching for compatibility with the low voltage/low current switching found on many boilers throughout the UK and Europe and is compatible as a replacement to all leading makes.
