Heavy Fuel Oil Solenoid Valves. 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 AVTA Thermostatically Operated Valve With Capillary Sensor – M&M Controls Danfoss – ASCO
When the correct valve size is chosen. We recommend using a stainless steel version of the AVTA valve. Above that number, the link between controlled temperature and water flow is no longer linear and temperature control is less precise.
Asco Joucomatic Pneumatic Automation. See or internet product catalogue for options. Danfoss RT Differential Switches. We recommend using NBR diaphragms for oil as cooling medium. Proportional means that on sensor dxnfoss change, the cooling water flow quantity change is proportional.
We recommend placing sensor in such a way that the whole of its surface is in contact with the medium. Danfoss Solenoid Valves – Marine. The reason is that the sensor is filled with a mixture of liquid and gas and the end of vanfoss capillary tube inside the sensor has to be in the liquid phase. 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.

Danfoss MBT Sensor. Asco Joucomatic Air Operated Valves.
Danfoss Nessie Solenoid Valves. Cryogenic Asco Solenoid Valves. Asco Dust Collector Systems.
Home Terms of Business Delivery Rates. Declaration from factory is available. 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 danfows. The mass charge and universal charge types must be installed with orientation according to AVTA technical brochure.
NBR diaphragms are available as accessory N, Svta, N eanfoss the technical brochure or our Internet product catalogue. Danfoss Nessie Power Packs. If the pressure is higher than the allowed, it is likely that the permanent influence shortens the life period of the internal parts of the WVTS valve.
DI water can destroy brass material, extract metals zinc from brass and pollute water. It contains 3 digits: How to select proper size of the valve depending on cooling water temperature is shown in the data sheet. Deionized water is an aggressive medium and can have bad influence on brass housing of the valve. Controller closes on rising temperature.
N – Danfoss AVTA 10 Thermostatically Operated Valve – M and M Controls Danfoss – ASCO
Generally the less sensor is immersed in water the slower and less accurate it reacts on temperature change. Danfoss Solenoid Valve Coils. Danfoss KP Temperature Switch. Danfoss KP Pressure Switch. Danfoss CS Pressure Switch.
Asco Joucomatic Manually Operated Valves. It is a very important advantage danfosw thermostatic valves because even at breakdowns in the power supply, the valve will still function, e. 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 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.
