QCV BELIMO: compact zone valve

The range of compact QCV (Quick Compact Valve) valves in the Belimo ZoneTight™ series has been expanded to include a 2-way control ball valve with a nominal diameter of DN 20, as well as a 3-way changeover ball valve with nominal diameters of DN 15 and DN 20. These valves offer many advantages, including:

• tight shut-off of the control valve, preventing energy losses caused by unwanted circulation in the system,
• manual setting of the kv coefficient in 2-way control ball valves,
• automatic adjustment to the set kv value,
• minimum energy consumption during operation and in standby mode,
• the option of a 24 V or 230 V power supply, with Close/Open, 3-point, analogue or MP-Bus® control
