687 MIX

3-Way rotating mixing valve kit

The adjustment kit Art. 687 MIX, thanks to the very small size, can be set up straight into the distribution box of radiant heating installations. The manufacture allows the mounting on the right side or on the left side of the manifold.

The unit for 1/2” circulating pumps (130 mm) consists of:

  • Compact 3-way rotating mixing valve with very high hydraulic performances (Kvs 6,8). It can be motorized with the ModvlvS range servomotors or with the other trade servomotors;
  • Pre-wired high efficiency synchronous circulating pump (for the models that include it);
  • Thermometer 0÷60°C;
  • Air vent valve;
  • Safety thermometer pit with fixed setting temperature 55°C (it can be ordered separately);
  • Ready for the addition of differential bypass valve (it can be ordered separately);
  • Direct connection to the manifold or by means of an eccentric piece 15 or 30 mm (manifold misalignment between the supply and the return).

Centre distance 210 mm
PN 10, maximum temperature 110°C (unit without circulating pump).
Connections: to the manifold 1” Male swivel connection or 1” Swivel nut; to the circuit 1” Male with 96 mm centre distance.

PED 2014/68/EU 4.3
For power up to 11 kW (with
Δt 8 K) and maximum flow 1200 l/h.
Kvs value: 4,6
Approximate data calculated with a 6 m nominal lifting power circulating pump.
For an accurate measuring or for higher flows, please refer to the curve.
Available circulating pumps:
Wilo Para 15/6 SC (P6)
Wilo Para 15/8 SC (P8)

Attention. Codes variance. For the version 1” Male please replace the letter “C” after the article with “G”.
For the versions without the circulating pump please skip the identification code of the pump “-P6” / “-P8”.
For example: 1“ male with swivel connection kit, without circulating pump with eccentric piece 15 mm: code 104687G-M3-15
