It opens at rising temperature and is therefore a good solution for a cooling function. Declaration from factory is available.

Proportional means that on sensor temperature change, the cooling water flow quantity change is proportional. Home Terms of Business Delivery Rates. This gives a high velocity over the valve seat which can generate noise. Danfoss Solenoid Valve Coils. 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.

What will happen if WVTS will be installed in application where pressure is maximum 16 bar? Permissible working pressure for the WVTS valve is 10 bar. Danfoss KP Temperature Switch. Temperature Transmitters and Sensors. Very high grade DI water will erode brass fast around 6 months and low quality DI will give a slow gradual attack on the brass. Asco Joucomatic Manually Operated Valves.

There is no problem with that. We recommend placing sensor in such a way that the whole of its surface is in contact with the medium. Please see our internet catalogue for relevant code numbers. We recommend the armoured version of capillary tube. Reaction time depends on two factors: 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.

In case of smaller boilers, we recommend the purpose-designed bio-mass valve BVTS.

Danfoss AVTA, Thermostatic valves with temperature sensitive sensor

Asco Joucomatic Air Service Equipment. Therefore, when ordering, please specify the need for the certificate.

The best score is for universal vanfoss mass charge. We recommend using a stainless steel version of the AVTA valve. Danfoss RT Pressure Switches. Instead the FJVA valve reacts to temperature of water flow through the valve body itself. Socla Self Acting – Actuated Valves.

Thermostatic valves valves are NC – normally closed. Danfoss Nessie Solenoid Valves. Danfoss RT Differential Switches. Danfoss RT Differential Switch.

Danfoss AVTA 25 Valve N

The mass charge and universal charge types must be installed with orientation according to AVTA technical brochure. It contains 3 digits: Cryogenic Asco Solenoid Valves. Turn the adjusting knob clockwise for higher temperature, counterclockwise dannfoss lower temperature. Proportional Asco Numatics Valves. If the cooling water temperature is close to that point, then more capacity is necessary to cool down the process medium.

The only requirement is that the cooling water temperature should be less or equal to the setting temperature. Danfoss internal standards demand our products resistance to such avya due to transport reason.


Asco Joucomatic Air Operated Valves. The AVTA valve opens at rising temperature cooling application. The valve is commonly used in connection with hydraulic stations, avtaa is often named the “fit and forget” valve, due to its immense reliability, proven throughout decades. A dirt filter should be always installed ahead of the FJVA valve, which has a small-diameter bypass in the valve body. Pressure and Temperature Switches.

Sirai Solenoid Valves – Pinch. Be social Take part. Hysteresis depends on the sensor filling. Type of the charge and whether sensor is in contact with liquid media or air. No, the bellows element can be replaced without uninstalling the valve from the application.

This action avfa be done even with the water in the system. How to select proper size of the valve depending on cooling water temperature is shown in the data sheet.

If the pressure is higher than the allowed, it is likely that the permanent influence shortens the life period of the internal parts of sanfoss WVTS valve. Is it possible to use AVTA for protecting bio-mass boilers? Danfoss KP Pressure Switch.
