TV 3S and TV 3XL are 3-way brass mixing valves for control of heating or cooling applications.

The valves are fitted with a wheel for manual mixing but can easily – and with advantage – be motorised, e.g. with our Thermomatic controls. All of the connection examples can be reversed. The scale is graded on both sides, and can also be reversed. All important parts can easily be replaced.

Our mixing valves can be supplied with the following connections and Kvs values.

Connections:

  • R15 / 1⁄2” Rp and G
  • R20 / 3⁄4” Rp and G
  • R25 / 1” Rp and G
  • Cu18
  • Cu22
  • Cu28

Pump flange R40 / 1 1⁄2” Rp can be pre-fitted on special order. It is also possible to combine different connection dimensions.

Kvs values:

2,5/4/6/8/10

TV 3XL has extra large flow and connections for large installations:

  • R32 / 1 1⁄4” Rp, Kvs 16
  • R40 / 1 1⁄2” Rp, Kvs 25
  • R50 / 2” Rp, Kvs 40
