Functions: heating and cooling. The temperature control is carried out by built-in clock. Switching time and necessary temperature can be adjusted individually. Room thermostat-clock is the manager for other thermostats. Setting range 5-40C

Thermostatic mixing valves

Thermostatic mixing valves are designed to regulate water temperature and applied:

For central management units of hot water or local regulation hydrants outlets. Or to use the heater with a double source of energy, using solar energy. In radiant heating systems with heating circuits such as “warm floor” or to limit the return temperature of the boiler.
If the system includes a circulation loop hot water, it must be installed check valve KB191 (see accessories) to prevent reverse current of cold water and cooling the mixed water outlet valve.

Additional description:

* Highly sensitive thermal element with good all-round contact with water provides a good iztmerenie temperatry even at low flow
* Easy to set the desired temperature
* Protection against scalding – the entrance to the hot water supply is automatically locked when the cold water supply disappears if the inlet temperature of hot water above the desired temperature of mixed water more than 10 K
* When filing cut off valve hot water – the entrance to the cold water supply is automatically locked
* Internal parts are made of a material fire resistant

Mixing valve

Power seal working surfaces due to torque and did not depend on the pressure in the PEX pipe.
Patented seal design Heating valve combines conical geometry of the saddle and the complex geometry of the surface of the ball, made with displaced center. O-ring located on the ball and seat in the body. Center seal is double eccentricity relative to the shaft. This technical know-how creates a shift in the end turn and approaching the saddle. The third eccentric to the axis of compression gives sealed surface without friction.

Wetted surface of the seal and seat are made so that the forces acting on the saddle and seal completely symmetrical about the center seal. The forces due to torque and provide uniform load on the seal.

Sealing ball is movably slide, which provides free movement of seals along the axis. The uniform compressive load causes the seal to form a saddle. Under the additional torque acting on the shaft, a saddle, being compressed, provides complete sealing systems. By turning the contact between the seal surface and a ball a ball is impossible. In the open position and the sealing ball is not in contact with the saddle and at the same time of cleaning the body cavity of mixing valve.

Characteristics of torque in vremyaraboty Taco mixing valves are the same. This fact increases the manageability of a ball.

Mixing valve

Seven traits of these Taco Valves

1. Logo Taco – the letter “T” in lozenge

If you notice a “typo” in the marking of type «Taco» or «Taco Bell» errors or logo (the letter «T» is not appearing on the label, as in, say, a square or circle), then in your hands the obvious fake.

2. «Made in Canada»

When buying a faucet Taco search for this inscription and the date of manufacture (month and year) on the product, as well as the original packaging with a bar code (pay attention to the contents of the barcode – continuous zeros in it of anything good does not say). Name of the country without a leading “Made in … (Eg, simply Canada or Mexico), issued by the unfortunate name of the vendor for the collection or the location of the one of the many small factory group Taco», indicates that this crane is made” in places not so remote, “to mention that this producer considered inappropriate or simply too shy. In the more talented fakes can see untranslatable play on words «Mode Canada», incapable of misleading pretentious buyer, but are designed for short-sighted and short-sighted. The main thing in this sentence no excuse «in», because the presence of his interpretation of the origin of the product and the falsification of this kind is much easier to attract legal liability. By the way, about the release date: in August the whole Italian industry rests, therefore, cranes, dated the 8 th month, by definition, can not be Italian.

3. Brass Taco valves

For Taco valves uses forged brass brand CW617N, as publicly reported on the case of the crane. Plagiarists do not stop to copy the inscriptions, but do not care about the quality of materials. To reduce costs, to simplify the design and use cheaper raw materials. Therefore, a forged valve differs from the original not only low price but also weight. At best case “left” fittings are made from secondary brass. Not so bad if the brittle and fragile material not withstand the pressure, much worse when it is dangerous to health. Some “illegal” taps, and this confirms the spectral analysis by an independent laboratory MISA, almost 90% composed of zinc. Many alleged brass products substantially exceeded the maximum content of harmful lead, whose numbers in the alloys according to GOST 1639 should be no more than 3%. Without exaggerating, we can say that such uncertified products poses a real threat to the lives of consumers.

4. Taco Balls

Taco Balls – Forged brass, polished.

To somehow compensate for the glaring ease the body, balls for fake fittings are made, as shown by the analysis of electrical steel used for rotors and stators of industrial engines. It adds the tap weight, but negatively affects quality: after all, steel rusts, causing leakage and leakage. To determine the presence of steel, parts, without disassembling the crane, you can by the presence of lubricants from mineral oils or petroleum products (in the original articles it is transparent, silicone), serving as a “Anticor.” Another way – use a magnet.

The authenticity of large cranes to define simpler, because the original Taco Balls machined from forged brass and the surface of their arguments to a mirror shine diamond grinding. If the fake brass fittings and there are balls, then the “low-test” and processed working concentrated I guess – they have rough surfaces and “muddy” in appearance. So the tightness of the crane, strength and ability to withstand pressures are low initially.

5. Stem Nut

Under the pen from the Taco Mixing Valves is nut to adjust seals, teflon seals and white mobile

on the rod (in the cheaper “copies” are made of black rubber seals). If in the process of long-term use Mixing valves will leak, tighten the nut should be, it will squeeze ring seal, and the crane back in working condition. With such a construction of his life increased to 20 thousand cycles, “open-closed”.

In the forgeries found different interpretations Stem, in the mass prop – the stock seems to be holding, but the seals are not pressed, and hence on the functioning of the crane does not affect.

6. “Intrinsically safe” design

“Intrinsically safe” design. In 2001, due to the tightening of European safety standard Mixing valves Bugatti has undergone a major revision, and now the stock is inserted is not from the outside, but inside the shell. Even with a significant excess of working pressure and fully otkruchennoy nut adjustment sealing option to fly rod removed. So the new original tap Bugatti nut can be unscrewed, but the stock can not be removed.

7. Color and shape of handles

And finally, the last touch. According to the official catalog of Taco Valves stain pen fittings as standard, depending on its destination: for water and steam – in black, and gas – in yellow. Other colors may indicate that the cranes brought to our unofficial way, or, most likely, before you fake.
