VTTV / VTTR / VTTB - 2-way, 3-way and 3-way (bypass) zone valves DN15-20, kvs 0.25-6.0
Valves for control of heating and cooling in fan-coil or chilled beams applications. The valves are intended to be used together with the thermal RTAN and RTAOM actuators. They are available as 2- and 3-way versions, as well as bypass versions. The valves have linear flow characteristics. The adapter for RTAOM…actuators is delivered with the valve.
