Four valve series of the Belimo ZoneTight™ product range – QCV, PIQCV, 6-way zone valve and the electronic pressure-independent 6-way zone valve – provide energy-saving, unproblematic room and zone control solutions in tight spaces.
The Quick Compact Valve QCV is available as a 2-way characterised control valve in the nominal diameters DN 15 and DN 20 with manually adjustable kv values and as a 3-way changeover ball valve in the same nominal diameters. As a pressure-independent characterised control valve, the Pressure Independent Quick Compact Valve PIQCV uses permanent hydraulic balancing to supply the precise amount of water required, at all times to all of the heating and cooling elements. The precise 6-way zone valve is used for the control of a combined cooling/heating element, usually a cooling or heating ceiling or an air-conditioning beam in a 4-line system.
The electronic, pressure-independent 6-way zone valve in standard sizes of DN 15 and DN 20 combines the benefits of two tried and tested Belimo valves in one. In contrast to the tried and tested 6-way zone valve, the integrated flow measurement and electronic flow control ensure the correct amount of water at any time should the differential pressure change or during partial loads.
