Mode of operation: The 6-way characterised control valve is adjusted by a rotary actuator. The actuator is connected by a modulating control system or a MP-Bus signal and moves the ball of the ball valve to the position dictated by the positioning signal. If the valve is adjusted in the clockwise direction (till the end stop), e.g. the cooling sequence is completely enabled; if the valve is adjusted in the counter-clockwise direction (90°), e.g. the heating sequence is completely enabled.

Pressure compensation: In cases of combined heating/cooling control elements, the medium remains in the control element when in the closed position (no heating or cooling). The pressure of the enclosed medium can rise or fall due to changes in medium temperature caused by the ambient temperature. The 6-way characterised control valves have an integrated pressure relief function for the purpose of compensating for such pressure changes. The pressure relief function is active in the closed position (45°) of the valve; reliable separation of Sequences 1 and 2 continues. For additional information, consult the notes for project planning for the 6-way characterised control valve.
