On the EVB there are no compromises on the capacity of the valve. Go to the valve selector.

EVB solenoid valves | Servo-operated valves | Danfoss

If this spring is very soft only a low differential pressure is needed to lift the diaphragm resulting in a high opening degree. Also the use of a special design of the diaphragm to increase its lift height increases the capacity.

Home EVB series Solenoid valves.

High Pressure Water Pumps. Up to IP67 Flange connections: Broad range of different ev20b and sealing materials The EVB range is available in three different body materials and with three different seal materials. Water-hammer damped design and built-in pilot filter ensures a reliable operation. High capacity in the entire pressure range At low differential pressures an additional closing force is needed to get a proper tightness.

The seal material determines the minimum temperature. Danross to 50 cSt Coil enclosure: 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 at high pressures.

Find the right valves 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. By controlling the closing speed at this stage the water hammer can be reduced.

For water and similar neutral media Flow range for water: If the equalising orifice is blocked by build-up of dirt, it can easily be removed and cleaned with compressed air. This program is especially for OEM applications demanding a robust solution and moderate danfoes rates.

Good external tightness even at high differential pressures The pressure in the valve tries to increase the gap between valve cover and valve body.

For water, oil, compressed air and similar neutral media Flow range from 0. On the Danfoss EVB valve it is done by having an optimized shape of the moulded diaphragm, a reinforcement giving an internal damping and a special damping cone giving a dwnfoss damping in the very late closing stage. This is possible because of the high quality EPDM type and the special dabfoss of the reinforced diaphragm reducing the internal stress level. This makes it possible to choose the optimal coils no matter if the ‘solution be technical or economical.

The filter is a self-cleaning type and is placed as a coaxial filter in the main valve flow.

Up to IP67 Thread connections: Broad range of standard options EB is a range in a modular program. For water, steam, oil, compressed air and gases Flow range for water: This version is called EVB and can be used in contaminated media that risk corrosion.

Material, media and market failures eLesson: Valve body in brass, dezincification resistant brass and stainless steel ensures that a broad variety of application can be covered. Insensitive to dirt The flow through the dirt sensitive pilot system is filtered on the EVB. 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.

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. In addition the closing speed can be adjusted by changing the equalising orifice. It makes it possible to use the standard brass version for common applications with limited risk of corrosion, and as trouble-shooter the EV B SS version with FKM and optionally with an isolating diaphragm.
