Flow direction - motorised valves

    Hello

    I have three motorised valves in my heating system - two Sunvic valves controlling up- and downstairs heat zones, and a Honeywell valve on the hot water tank.

    I have noticed that the flow through the motorised valves is the opposite direction to the arrows shown on the valves themselves - which I suspect is a result of feed and return being switched when the boiler was replaced.

    The valves seem to be working fine, but I wondered if this was likely to lead to problems with the valves over time...

    Any thoughts??

    Thanks
    Damian

    Most motorised valves do not mind what direction they are installed.
    Some, however, do because of the paddle valve inside. If it is reversed the flow to another zone can force the paddle open & the result would be unwanted heat in a zone whilst off.

    For example, Sauter/EPH valves can do this.
