The tool is intended to make it easy for installers and end-users to specify the correct industrial solenoid valves for a range of standard applications. Broad range of standard options EB is a range in a modular program.

Spare parts kits for EVB. Up to IP67 Thread connections: If the equalising orifice is blocked by build-up of dirt, it can easily be removed and cleaned dxnfoss compressed air. Basic valve and coil theory eLesson: Due to the increased thickness on the sealing point of the diaphragm of the EVB valve only a very low closing force is needed from the spring.

Danfoss EVB water hammer damped solenoid valve In general it is the closing speed of the valve that determines the water hammer phenomenon. This means you don’t need an assisted lift solenoid valve danfoas in most of the cases.

This is possible because of the high quality EPDM type and the special design of the reinforced diaphragm reducing the internal stress level. For water, steam, oil, compressed air and gases Flow range for water: This is done by the closing spring.

Also the use of danfows special design of the diaphragm to increase its lift height increases the capacity. Good external tightness even at high differential pressures The pressure in the valve tries to increase the gap between valve cover and valve body.

High Pressure Water Pumps.

Built-in pilot filter as standard, adjustable closing time and enclosures up to IP67 ensures optimal performance even under critical dnfoss conditions. Direct and indirect servo operated valves eLesson: By controlling the closing speed at this stage the water hammer can be reduced. To avoid leakage because of the gap the moulded diaphragm has a built-in a-Ring giving an excellent sealing between valve cover and valve body even ddanfoss high pressures. Insensitive to dirt The flow through the dirt sensitive pilot system is filtered on the EVB.

The valve is designed with cast iron valve body and flanged connection. Wide coil range up to IP The valve is designed with very smooth internal shape of the valve body.

They are available normally closed or normally open. This makes it possible to use the EVB for’ several brines. Direct operated solenoid valves eLesson: For water and similar neutral media Flow range for water: The seal material determines the minimum temperature.

EV220B, servo-operated solenoid valves

The filter is a self-cleaning type and is placed as a coaxial filter in the main valve flow. If this spring is very soft only a low differential pressure is needed to lift the diaphragm resulting in a high opening degree.

For water, oil, compressed air and similar neutral media Flow range from 0. In addition the closing speed danfosss be adjusted by changing the equalising orifice. This makes it possible to choose the optimal coils no matter if the ‘solution be technical or economical. adnfoss

On the EVB there are no compromises on the capacity of the valve. This results in a very good external tightness. Up to 10 bar Viscosity: This version is called EVB and can be used in contaminated media that risk corrosion.

High capacity in the entire pressure range At low differential pressures an additional closing force is needed to get a proper tightness.

During the movement of the diaphragm the rubber is stressed and relieved several times and often determines the lifetime of the valve.

Material, media and market failures eLesson: Up to 50 cSt Coil enclosure:
