With the use of the valves TM 2000 are obtained the following advantages:

• Increasing the combustion efficiency of the heat generator.
• Avoiding the risk of destructive thermal shock.
• Significant lengthening of the working life of the boiler.

The thermostatic mixing valve TM 2000 aren’t equipped with electrical / electronic devices, with consequently great benefit of reliability and simplicity of system installation and maintenance. The “one single piece” thermostat-lid allows a quick and easy replacement of the thermostat. To ensure accurate precision, the thermostatic sensor is immersed directly into the fluid. Operation temperature range: 5 -110 ° C. Maximum operating pressure:10 bar. TM 2000 mixer valves are available in 4 sizes (G ¾, “G 1”, G 1 ¼”, G 1 ½”) .

The thermostatic sensor is immersed directly in the fluid. According to the temperature value set (temperature settings available – standard version: 45 – 50 – 55 – 62 – 72 - 78 °C), the valve mixes the fluid flows so that the fluid flow returning to boiler is always at the right set-point temperature. On specific request, TM 2000 mixer valve may be supplied with temperature set values different from those of the standard valve set.

• Valve body: Cast Iron GJL220
• Thermostatic cartridge: Die-cast aluminium  AB 46100 Al Si 11 Cu 2
• Spring: Steel AISI 302 EN 10204-3.1

INSTRUCTIONS

WARNING! BEFORE CARRYING OUT ANY OPERATION

•  Make sure the pump is off.
• Close the three-way ball valves and discharge the system.

The valve can be fitted in any position. To reproduce the sample circuits shown after, refer to the “Gate” see fig. 2

1. Switch off the pump
2. Close the three-way ball valves
3. Completely unscrew the two screws on the TM 2000 cartridge lid
4. Using a Ch 10 wrench, rotate the lid and take the gate to the required position
5. Return the 2 screws to their original position and tighten
6. Open the three ball valves and recharge the system if necessary
7. The system is now ready to use
8. Switch on the pump.

TM2000

Adjustable thermostatic mixer valve for centralised heating systems ( also for thermal solar and biomass fuel systems), MUT series TM 2000. To apply when it is essential to ensure the return of hot water (at a minimum temperature level) to the boiler , thus ensuring a sufficiently high thermal regime of operation to prevent vapour condensation in the smoke- stack. Threaded connections: G ¾” , G 1” , G 1 ¼”, G 1 ½”F. Monolithic cartridge lid (one single piece). Valve body material: Cast Iron GJL200; thermostatic cartridge lid material: Die-cast aluminium AB 46100 Al Si 11 Cu ; Spring: Stainless Steel AISI 302 EN 10204-3.1. The thermostatic sensor is immersed directly into the fluid. Fluid’s temperature limits 5 ÷ 110 °C. Nominal pressure: PN 10 bar. Range of mixed water Temperature’s adjustment available: 45 °C ÷ 50 °C ÷ 55 °C ÷ 63 °C ÷ 72 °C ÷ 78 °C .
