Vacuum Service Asco Valves. Instead the FJVA valve reacts to temperature of water flow through the valve body itself. Danfoss Electronic Soft Starters. Controller closes on rising temperature. The inspection certificate dabfoss.

Asco Joucomatic Pneumatic Accessories. To ensure thermal conductivity between the sensor and the immersion pocket wall, it is recommended to use heat-conductive compound, available as avat accessory under the code number E 5 g or E g. Sirai Solenoid Valves – Pinch. Pressure and Temperature Switches.

The AVTA valve opens at rising temperature cooling fanfoss. If you do not know the water flow rate required, there is a table which will help you determine it, but you will need xanfoss know the required capacity of heat removal in refrigeration tons TR or in KW.

Yes, you should use the AVTA thermostatic valve. Danfoss Spare Parts For Contactors. Type of the charge and whether sensor is in contact with liquid media or air. This action can be done even with the water in the system. This gives a high velocity over the valve seat which can generate noise.


First you must know the flow rate of water required, the regulation temperature at the sensor, and the allowable pressure differential across the valve. Terms of Use Privacy policy General information Cookies.

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

N – Danfoss AVTA 10 Thermostatically Operated Valve – M and M Controls Danfoss – ASCO

Danfoss internal standards demand our products resistance to such temperature due to transport reason. Is it possible to use AVTA for protecting bio-mass boilers? We always recommend installing a filter type FV in the pipe system ahead of valves, especially in cases when the medium could be contaminated or include dirt particles.

For adsorption charge reaction time is longer than for other two fillings. Go to dantoss section Danfoss Media Center.

We may in this case recommend a bigger valve size than in cases when the cooling water temperature is lower. Go to career section Working at Danfoss. 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. Yes you can use it, but it will effect the response time and accuracy of the regulation, svta normally the valves are used in liquids like water or oil.


The mass charge and universal charge types must be installed with orientation according to AVTA technical brochure. Danfoss Nessie Water Motors. Danfoss Electronic Motor Contactors.

Danfoss AVTA, Thermostatic valves with temperature sensitive sensor

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. NBR diaphragms are available as accessory N, N, N see the technical brochure or our Internet product catalogue. Asco Joucomatic Air Operated Valves. Please see our internet product catalogue.

Generally the dznfoss sensor is immersed in water the slower and less accurate it reacts on temperature change. The production date stamp is placed on the valve body. It is a very important advantage of thermostatic valves because even at breakdowns in the power supply, the valve will still function, e.

Danfoss RT Differential Switches. Go to About section Our Engineering. You have to use the setting knob on the upper side of the valve. Danfoss CS Pressure Switch.
