The reason is that the sensor is filled with a mixture of liquid and avtz and the end of the capillary tube inside the sensor has to be in the liquid phase.

AVTA, Thermostatic valves with temperature sensitive sensor – FAQ

Type of the charge and whether sensor is in contact with liquid media or danfoss. Hysteresis depends on the sensor filling. To calibrate, use thermometer to measure temperature near sensing point. Danfoss self-acting cooling water valves for accurate flow control based on sensor temperature Capillary sensor with adsorption charge, mass charge or universal charge Open on rising temperature Brass or stainless steel valve body Atva extremely aggressive media, also available in titanium please contact us.

How to select proper size of the valve depending on cooling water temperature is shown in the data sheet. The inspection certificate 3. Proportional means that on sensor temperature change, the cooling water flow quantity change is proportional. Asco Joucomatic Pneumatic Accessories. Thermostatic valves type AVTA work independent from media differential pressure up to 10 bar. We recommend the armoured version of capillary tube.

Please see our internet product catalogue. Position 1 is the minimum temperature of the specific range position, and 5 is the highest. See or internet product catalogue for options. Temperature Transmitters and Sensors.

Cryogenic Asco Solenoid Valves. Therefore, when ordering, please specify the need for the certificate. Go to media section Danfoss Media Center. DI water can destroy brass material, extract metals zinc from brass and pollute water. Socla Self Acting – Actuated Valves.

Go to procurement section Procurement. Go to About section Our Engineering. Thermostatic valves valves are NC – normally closed.

Controller closes on rising temperature. Yes, but be sure to observe the flow direction arrow on valve body, and install accordingly. The only requirement is that the cooling water temperature should be less or equal to the setting temperature. AVTA, Thermostatic valves with temperature sensitive sensor AVTA thermostatic operated water valves are widely used for temperature control in many different sorts of equipment and installations where cooling is required.

Deionized avya is an aggressive medium and can have bad influence on brass housing of the valve. If the noise comes from the valve body, it may mean that the opening degree of the valve cone is too small.

This action can be done even with the water in the system. Go to career section Working at Danfoss.

Very high grade DI water will erode vanfoss fast around 6 months and low quality DI will give a slow gradual attack on the brass. Agta that number, the link between controlled temperature and water flow is no longer linear and temperature control is less precise. Danfoss CS Pressure Switch. Yes you can use it, but it will effect the response time and accuracy of the regulation, because normally the valves are used in liquids like water or oil.

Danfoss KP Pressure Switch. What will happen if WVTS will be installed in application where pressure is maximum 16 bar? Terms of Use Privacy policy General information Cookies. If you need a very accurate figure, you should check the temperature setting with a thermometer.

Danfoss RT Differential Switches. As we do danfose know exact type and composition of alcohol, we suggest forwarding above information to manufacturer of the mixture, who can assure proper functionality with NBR and EPDM seal materials. Danfoss Electronic Motor Contactors. Danfoss Nessie Solenoid Valves.

003N1144 AVTA 10 Danfoss Thermostatic valve 10-80°C

Danfoss Solenoid Valves – Marine. Danfoss internal standards demand our products resistance to such temperature due to transport reason.

A dirt filter should be always installed ahead of the FJVA valve, which has a small-diameter bypass in the danvoss body. 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.
