Thermostatically operated valves are used for the continuous adjustment and proportional to the flow, in relation to the temperature and the setting of the sensor.
The range of thermostatic valves comprises a series of industrial products for the adjustment of refrigeration systems and heating systems.
The valves operate without the need for auxiliary power supply such as electricity or compressed air.

The valves are especially suitable for the regulation of the temperature becouse they constantly adjust the flow according to the needs.
The required temperature is maintained constant without waste of:

  • Cooling water in cooling systems
  • Hot water or steam heating systems.

Thermostatic valves are made up of three elements:

  • Section of adjustment knob, spring and reference scale.
  • Valve body with nozzle, cone closing and sealing elements.
  • Thermostatic element hermetically sealed sensor, bellows and charged.

You combine these three elements, install the valve and the sensor at the point where you want to adjust the temperature.

The valves AVTA for cooling systems are widely used for temperature adjustments in the machinery and installations where it is needed refrigeration.
These start with the increase of temperature and leave the fluid flow.
They can be installed on the water supply line of refrigeration, that on the return line.
The standard version of AVTA thermostatic valve can be used with fresh water or neutral brine.
