1 T-6-way valve NPT threads Standard control valves 6-way valve for change-over systems

2 IMI T / Control valves / T-6-way valve NPT threads T-6-way valve NPT threads The 6-way valve solution enables various control set-ups for heating and cooling in sequence on one terminal unit. Provides automatically adopted settings of max. flows for heating and cooling modes together with T-Modulator and T-Slider 160 Plus or T-Slider 160 KNX R24. Key features > > Easy commissioning and balancing Provides automatically adopted settings of max. flows for heating and cooling mode together with T-Modulator and T-Slider 160 Plus or T-Slider 160 KNX R24. > > Precise flow control Provides uniquely shaped EQM characteristic for best modulating control together with T-Modulator. > > Easy troubleshooting Provides flow and differential pressure measuring for system diagnostics and pump optimization together with T-Modulator. > > Compact installation Saves space by using one terminal unit for heating and cooling.

4 IMI T / Control valves / T-6-way valve NPT threads Installation Flow distribution Kv/Kvs [%] *) Pressurisation NOTE! When designing the pressurisation system: please consider that change-over systems have hydraulic interaction between the cooling and the heating system via the terminals, which cause a fluid mass transfer from the cooling to the heating system. For further information please contact IMI Hydronic Engineering. Example valve + bracket See ccessories 45 *) Pressure balance function: Pressure connection between port 1 and 2, at 32 to 50, for proper pressurisation of the terminal at zero flow. NOTE! ny control valve should be connected to port 3.
