The only requirement is that the cooling water temperature should be less or equal to the damfoss temperature. The valve is commonly used in connection with hydraulic stations, and is often named the “fit and forget” valve, due to its immense reliability, proven throughout decades. If the noise comes from the valve body, it may mean that the opening degree of the valve cone is too small.

Above that number, the link between controlled temperature and water flow is no longer linear and temperature control is less precise.

Asco Joucomatic Pneumatic Accessories. Cryogenic Asco Solenoid Valves. Very high grade DI water will erode brass fast around 6 months dafnoss low quality DI will give a slow gradual attack on the brass. Danfoss Nessie Power Packs. What will happen if WVTS will be installed in application where pressure is maximum 16 bar?

Danfoss Electronic Soft Starters. Danfoss Temperature Sensors – Marine. 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. It opens at rising temperature and is therefore a good solution for a cooling function.


AVTB is self-acting temperature controller used to control the water temperature in hot water tanks, heat exchangers, oil preheaters, etc. Go to About section Our Engineering. Sirai Solenoid Valves – General Purpose. Also the sensor must not be orientated upwards. No, unfortunately elements with stainless steel capillary tube are not available, but we recommend using a thermostatic element with stainless fanfoss armor, protecting the capillary tube”s entire length.

Temperature Transmitters and Sensors. Danfoss MBT Sensor.

Danfoss AVTA Thermostatically Operated Valve With Capillary Sensor – M&M Controls Danfoss – ASCO

See or internet product catalogue for options. The AVTA valve opens at rising temperature cooling application. Danfoss Solenoid Valve Coils.

Self-acting means that thermostatic valves operate without the supply of external auxiliary energy such as electricity or compressed air. It contains 3 danfos Danfoss Spare Parts For Contactors. Please see our internet product catalogue. This gives a high velocity over the valve seat which can generate noise. We may in this case recommend a bigger valve size than in cases when the cooling water temperature is lower.

AVTA, Thermostatic valves with temperature sensitive sensor

Therefore, when ordering, please specify the need for the certificate. Yes, but be sure to observe the flow direction arrow on valve body, and install accordingly. Yes, AVTA is a great solution for biomass boilers above kW, preventing overheating of the boiler. If the cooling water temperature is close to that point, then more capacity is necessary to cool down the process medium.

Instead the FJVA valve reacts to temperature of water flow through the valve body itself. 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. The internal design of the universal charge sensor requires danflss mounting position – with the red line on top.


003N3132 AVTA 20 Danfoss Thermostatic valve 0-30°C

To calibrate, use thermometer to measure temperature near sensing point. DI water can destroy brass material, extract metals zinc from brass and pollute water. Is it possible to use AVTA for protecting bio-mass boilers? Position 1 is the minimum temperature of the danfose range position, and 5 is the highest. Danfoss MBT Std.

We recommend placing sensor in such a way that the whole of its surface is in contact with the medium. Vacuum Service Asco Valves.

Thermostatic valves valves are NC – normally closed. Generally the less sensor is immersed in water the slower and less accurate it reacts on temperature change. For valves already produced, we are therefore not able to issue this certificate.

Asco Joucomatic Manually Operated Valves.

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

Controller closes on rising temperature. Sirai Solenoid Valves – Pinch. This action can be done even with the water in the system. Reaction time depends on two factors: Type of the charge and whether sensor is in contact with danfoes media or air.

Danfoss internal standards demand our products resistance to such temperature due to transport reason. AVTA are controlled only by an application temperature. Danfoss RT Temperature Switch.
