Yes, you should use the AVTA thermostatic valve. Danfoss Spare Parts For Contactors. Danfoss Temperature Sensors – Marine. Therefore, when ordering, please specify the need for the certificate. First you must know the flow rate of water required, the regulation temperature at the sensor, and the allowable pressure differential across the valve.

It opens at rising temperature and is therefore a good solution for a cooling function. The first two are related to production week and the third one to production year.

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

Socla Self Acting – Actuated Valves. Yes, but be sure to observe the flow direction arrow on valve body, and install accordingly. Please see our internet product catalogue.

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

Asco Joucomatic Manually Operated Valves. Danfoss RT Differential Switch. Danfoss RT Differential Svta. NBR diaphragms are available as accessory N, N, N see the technical brochure or our Internet product catalogue. The valve is commonly used in connection with hydraulic stations, and is often named the “fit and forget” valve, due dajfoss its immense reliability, proven throughout decades. To ensure thermal conductivity between the sensor and the immersion pocket wall, it is recommended to use heat-conductive compound, available as an accessory under the code number E 5 g or E g.

Danfoss MBT Std. Vacuum Service Asco Valves. Proportional Asco Numatics Valves.

Magnetic Latch Asco Valves. In case of smaller boilers, we recommend the purpose-designed bio-mass valve BVTS. Asco Dust Collector Systems. Yes, you can order the complete thermostatic element for each ava of AVTA. Reaction time depends on two factors: If the noise comes from the valve body, it may mean that the opening degree of the valve cone is too small.

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. Turn the adjusting knob clockwise for higher temperature, counterclockwise for lower temperature. Home Terms of Business Delivery Rates.

If the cooling water temperature is close to that point, then more capacity is necessary to cool down the process medium. Go to About section Our Engineering. AVTA are controlled only by an application temperature.

dznfoss Sirai Solenoid Valves – Total Isolation. Thermostatic valves valves are NC – normally closed. As we do not 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 internal standards demand our products resistance to such temperature due to transport reason.

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. Controller closes on rising temperature.

The production date stamp is placed on the valve body. We recommend the armoured version of capillary tube. However if you remove the 8 screws that fix the valve body and assemble in the reverse position, you will be able to use the valve for heating purposes, always respecting the temperature that the bulb is specified for.

Danfoss Solenoid Valves – Marine. Avvta only requirement is that the cooling water temperature should be less or equal to the setting temperature. We may in this case recommend a bigger valve size than in cases when the cooling water temperature is lower.

To calibrate, use thermometer to measure temperature near sensing point. Generally the less sensor is immersed in water the slower and less accurate it reacts on temperature change.

Hysteresis depends on the sensor filling. Dwnfoss water is an aggressive medium and ranfoss have bad influence on brass housing of the valve. We recommend placing sensor in such a way that the whole of its surface is in contact with the medium.

We recommend using NBR diaphragms for oil as cooling medium. Permissible working pressure for the WVTS valve is 10 bar. We recommend using a stainless steel version of the AVTA valve.

It is a very important advantage of thermostatic valves because even at breakdowns in the power supply, the valve will still function, e. Avts gives a high velocity over the valve seat which can generate noise.
