Siemens Building Technologies Division has expanded its comprehensive Acvatix range of valves with 6-way control ball valves especially suited for use in heated/chilled ceiling applications. Because of its special design, a 6-way control ball valves replaces four conventional valves, including actuators, in a 4-pipe heated/chilled ceiling; since there is only actuator, it occupies only one data point. Less effort for installation, commissioning and cabling as well as decreased space requirements reduce the complexity of the plant and result in lower costs.
The new 6-way control ball valves have a built-in pressure compensation function which is active when the valve is in the closed position (i.e. when no heating or cooling is needed). This prevents over- or under-pressure which might otherwise damage the heated/chilled ceiling. In addition, the valves are bubble- and water-tight as per EN12666-1, Class A.
The finely graduated flow values (kvs) of the new 6-way control ball valves allow a great deal of planning flexibility since there is a suitable valve even for large rooms and high heating/cooling demands. kvs values precisely adjusted to the flow demand offer excellent energy efficiency. Different screw fittings allow the control ball valves to be attached to different pipe dimensions without additional pipe expanders or reducers.
