The program comes complete with the clip-on coil and IP65 electrical plug and has been carefully designed to simplify product selection. In addition the closing speed can be adjusted by changing the equalising orifice.
High Pressure Water Pumps. 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 viscous damping in dafoss very late closing stage.
Wide coil range up to IP Water-hammer damped design and built-in pilot filter ensures a reliable operation.
Learn more about our valve range in the Danfoss Learning eLessons eLesson: Home EVB series Solenoid valves.
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. This is done by the closing spring.
Up to IP67 Thread connections: 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. Basic valve and coil theory eLesson: Material, media and market failures eLesson: This results in a very good external tightness.

Up to IP67 Flange connections: This makes it possible to choose the optimal coils no matter if the ‘solution be technical or economical. Due to the increased thickness on the sealing point of the diaphragm of the EVB valve only a very ef220b closing force is needed from the spring.
Why not open an account? This means you don’t need an assisted lift solenoid valve as in most of the cases. They are available normally closed or normally open. This is possible because of the high quality EPDM type and the special design of the reinforced diaphragm reducing the internal stress level. danfoxs
Go to the valve selector. During the movement of the diaphragm the rubber is stressed and relieved several times and often determines the lifetime of the valve.
Broad range of standard options EB is a ec220b in a modular program.
EV220B, servo-operated solenoid valves
Built-in pilot filter as standard, adjustable closing time and enclosures up to IP67 ensures optimal performance even under critical working conditions.
For water, steam, oil, compressed air and gases Flow range for water: Direct and indirect servo operated valves eLesson: EVB, servo-operated solenoid valves.
Direct operated solenoid valves eLesson: This makes it possible to use the EVB for’ several brines. By controlling the closing speed at this stage the water hammer can be reduced.
Danfoss EVB ( series) Servo-operated 2/2-way solenoid valves
Danfoss EVB water hammer fv220b solenoid valve In general it is the closing speed of the valve that determines the water hammer phenomenon. Up to 10 bar Viscosity: If this spring is very soft only a low differential pressure is needed to lift the diaphragm resulting in a high opening degree. Broad range of different body and sealing materials The EVB range is available in three different body materials and with three different seal materials.
Good external tightness even dahfoss high differential pressures The pressure in the valve tries to increase the gap between valve cover and valve body.
