Danfoss wanted a qualified answer to this question before going ahead with the development of a whole new series of two-way motorised valves intended primarily for district heating installations.

This is the reason why we took the latest techniques and started with a thorough market survey; a survey that brought us into contact with a large number of customers. We listened to them and from their answers were able to formulate four customer requirements as being typical where district heating motorised valves are concerned:
– Small overall dimensions
– Simple operation
– Service-friendliness
– Good regulation characteristics
