We recommend placing sensor in such a way that the whole of its surface dangoss in contact with the medium. Danfoss Solenoid Valve Coils. Danfoss internal standards demand our products resistance to such temperature due to transport reason. Danfoss Solenoid Valves – Marine. Asco Joucomatic Manually Operated Valves. The only requirement is that the cooling water temperature should be less or equal to the setting temperature.

Danfoss AVTA / B Thermostatically Operated Valve With Capillary Sensor – M and M Controls

We recommend using NBR diaphragms for oil as cooling medium. The reason is that the sensor is filled with a mixture of liquid and gas and the end of the capillary tube inside the sensor has to be in the liquid phase.

The AVTA can operate at 16 bar and thus be used without problems. It opens at rising temperature and is therefore a good solution for a cooling function. Asco Dust Collector Systems. Go to About section Our Engineering. If the noise comes from the valve body, it may mean that the opening degree of the valve cone is too small. We recommend using a stainless steel version of the AVTA valve.


Danfoss Nessie Water Motors. We recommend the armoured version of capillary tube. Danfoss Temperature Sensors – Marine.

No, unfortunately elements with stainless steel capillary tube are not available, but we recommend using a thermostatic element with stainless steel armor, protecting the capillary tube”s entire length.

Be social Take part. Thermostatic valves type AVTA work independent from media differential pressure up to 10 bar. The first two are related to production week and the third one to production year. You have to use the setting knob on the upper side of the valve. Sirai Solenoid Valves – Total Isolation. The AVTA valve opens at rising temperature cooling application.

Heavy Fuel Oil Solenoid Valves. Instead the FJVA valve reacts to temperature of water flow through the valve body itself. Danfoss Spare Parts For Contactors. The mass charge and universal charge types must be installed with orientation according to AVTA technical brochure. No, the sanfoss element can be replaced without uninstalling the valve from the application.

AVTA, Thermostatic valves with temperature sensitive sensor – FAQ

Danfoss Electronic Motor Contactors. Asco Joucomatic Air Service Equipment. Go to media section Danfoss Media Center.


Danfoss RT Differential Switches. Danfoss Electronic Soft Starters. There is avya problem with that. This gives a high velocity over the valve seat which can generate noise. Asco Joucomatic Pneumatic Accessories. The best score is for universal and mass charge. This action can be done even with the water in the system.

003N0109 Danfoss AVTA 25 – with adsorption charge

We may in this case recommend a bigger valve size than in cases when the cooling water temperature is lower. Danfoss MBT Std.

Danfoss MBT Sensor. If the cooling water temperature is close ranfoss that point, then more capacity is necessary to cool down the process medium. Proportional Asco Numatics Valves. Only the adsorption charge type sensor can be installed in any direction. Danfoss Group Global English U.

If you do not know the water flow rate required, there is a table which will help you determine it, but you will need to know the required capacity of heat removal in refrigeration tons TR or in KW. If the pressure is higher than the allowed, it is likely that the permanent influence shortens the life period of the internal parts of the WVTS valve.
