Thermostar

The Flühs thermostatic valve is a product which stands out from competing products thanks to its new construction and the use of high-quality components and precision turned parts made of special brass.

The Thermostar can be used in both traditional thermostatic faucets and shower panels.

As the most up-to-date generation of thermoelements and extremely narrow tolerances are used for the components, the Thermostar guarantees a constant water temperature with a high reaction speed.

The patented differential drive is used in the upper control unit and prevents automatic operation of the thermostatic valve caused by fluctuations in pressure

In addition, the patented emergency control permits manual operation of the Thermostar even in the event of failure of the thermoelement.

If the cold water inflow fails, the Thermostar is automatically switched off by means of the scald protection device.

The basic task of the Thermostar is to compensate for variations in temperature and pressure in the cold or warm water inflow at a preset temperature in order to maintain a constant temperature.

For this purpose, the Thermostar contains a thermoelement which contracts if the temperature falls and expands if it rises. This thermoelement is filled with a special wax.

The thermoelement is fitted in the middle of the Thermostar, and mixed water constantly flows around it when it is in use.

This element is connected to a plunger which, as the thermoelement moves, controls the flow of hot and cold water. If the mixed water is too hot, more cold water is added, and vice versa. The spindle of the Thermostar is moved via the handle in order to set the required temperature of the mixed water. In turn, this is part of the differential drive which activates the plunger via a cylinder.

Turning the spindle to the right makes the setting colder, and turning it to the left increases the temperature of the mixed water.

The thermoelement and plunger are mounted dynamically between two high-precision springs.

The use of ring sieves made of high-alloy stainless steel prevents particles of dirt penetrating the Thermostar together with the incoming water and resulting in a malfunction.
