DI water can destroy brass material, extract metals zinc from brass and pollute water. A dirt filter should be always installed ahead of the FJVA valve, which has a small-diameter bypass in the valve body.

003N0109 Danfoss AVTA 25 – with adsorption charge

We recommend using NBR diaphragms for oil as cooling medium. The only requirement is that the cooling water temperature should be less or equal to the setting temperature.

This depends on the sensor element used. Go to procurement section Procurement.

We recommend using a stainless steel version of the AVTA valve. Danfoss Nessie Solenoid Valves. Danfoss RT Differential Switch. The AVTA can operate at 16 bar and thus be used without problems. If the noise comes from the valve body, it may xvta that the opening degree of the valve cone is too small.

Deionized water is an aggressive medium and can have bad influence on brass housing of the valve. See or internet product catalogue for options. This action can be done even fanfoss the water in the system. Generally the less sensor is immersed in water the slower and less accurate it reacts on temperature change.


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

Yes, but be sure to observe the flow direction arrow on valve body, and install accordingly. Danfoss MBT Sensor. The inspection certificate 3.

Also the sensor must not be orientated upwards. Therefore, when ordering, please specify the need for the certificate. Asco Numatics Control Valves.

AVTA Thermostatic Valves

Danfoss Electronic Motor Starters. Pressure and Temperature Switches. Be social Take part. 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 For extremely aggressive media, also available in titanium please contact us.

You have to use the setting knob on the upper side of the valve. 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. Yes, AVTA is a great solution for biomass boilers above kW, preventing overheating of the boiler. It is a very important advantage of thermostatic valves because even at breakdowns in the power supply, the valve will still function, e.

Externally Operated Asco Valves. Hysteresis depends on the sensor filling. 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.

Declaration from factory is available. Thermostatic valves type AVTA work independent from media differential pressure up to 10 bar. Sirai Solenoid Valves – Pinch. Asco Joucomatic Manually Operated Valves. Asco Joucomatic Air Service Equipment. 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. 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.


Heavy Fuel Oil Vanfoss Valves.

Danfoss Temperature Sensors – Marine. For valves already produced, we are therefore not able to issue this certificate. However if you remove the 8 screws that fix the valve body and assemble avga the reverse position, you will be able to use the valve for heating purposes, always respecting the temperature that the bulb is specified for.

Position danoss is the minimum temperature of the specific range position, and 5 is the highest. Danfoss RT Temperature Switch. To calibrate, use thermometer to measure temperature near sensing point. If the pressure is higher than the allowed, it is likely that the permanent influence shortens the avt period of the internal parts of the WVTS valve. Yes, you should use the AVTA thermostatic valve.

Instead the FJVA valve reacts to temperature of water flow through the valve body itself.

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

Sirai Solenoid Valves – General Purpose. Permissible working pressure for the WVTS valve is 10 bar.

Danfoss Nessie Manual Valves. We recommend the armoured version of capillary tube.
