High capacity in the entire pressure range At low differential pressures an additional closing force is needed to get a proper tightness.
This is done by the closing spring. Broad range of different body and sealing materials The EVB range is available in three different body materials and with three different seal materials. For water and similar neutral media Flow range for water: Valve body in brass, dezincification resistant brass and stainless steel ensures that a broad variety of application can be covered.
Water-hammer damped design and built-in pilot filter ensures a reliable operation. By controlling the closing speed at this stage the water hammer can be reduced. Go to the valve selector.
This means you don’t need an assisted lift solenoid valve as in most of the cases. The valve is designed with very smooth internal shape of the valve body. Also the use of a special ev22b0 of the diaphragm to increase its lift height increases the capacity. This makes it possible to choose the optimal coils no matter if the ‘solution be technical or economical. In reality the water hammer comes just before the valves closes.
Danfoss EVB Solenoid Valves
Insensitive to dirt The flow through the dirt sensitive pilot system is filtered on the EVB. High Pressure Water Pumps. Why not open an account?
Up to 50 cSt Coil enclosure: EVB, servo-operated solenoid valves. The program comes complete with the clip-on coil and IP65 electrical plug and has been carefully designed to simplify product selection. If the dajfoss orifice is blocked by build-up of dirt, it can easily be removed and cleaned with compressed air.
In addition the closing speed can be adjusted by changing the equalising orifice. The seal material determines the minimum temperature. Up danfiss IP67 Flange connections: Material, media and market failures eLesson: Spare parts kits for EVB.
This results in a very good external tightness.
EV220B, servo-operated solenoid valves
To avoid leakage because of the gap the moulded diaphragm has a built-in a-Ring giving an sv220b sealing between valve cover and valve body even at high pressures. This program is especially danfooss OEM applications demanding a robust solution and moderate flow rates. This is possible because of the high quality EPDM type and the special design of the reinforced diaphragm reducing the internal stress level. During the movement of the diaphragm the rubber is stressed and relieved several times and often determines the lifetime of the valve.
They are available normally closed or normally open. The valve is designed with cast iron valve body and flanged connection.
Direct operated solenoid valves eLesson: Accessories such as isolating diaphragm unit, NO-unit, manual-operating unit and adjustable equalising orifice are easily fitted on the valve, and the usual wide coil range can be used. If this spring is very soft only a low differential pressure is needed to lift the diaphragm resulting in a high opening degree. The tool is intended ev22b make it easy for installers and end-users to specify the correct industrial solenoid valves for a range of standard applications.
On the EVB there are no compromises on the capacity of the valve. Direct and indirect servo operated valves eLesson: Home EVB series Solenoid valves.

Basic valve and coil theory eLesson: Up eg220b IP67 Thread connections: This makes it possible to use the EVB for’ several brines. For water, steam, oil, compressed air and gases Flow range for water: Danfoss EVB water hammer damped solenoid valve In general it is the closing speed of the valve that determines the water hammer phenomenon.
Good external tightness even at high differential pressures The pressure in the valve tries to increase the gap between valve cover and valve body. Wide coil range up to IP The filter is a self-cleaning type and is placed as a coaxial filter in the main valve flow. This version is called EVB and can be used in contaminated media that risk ef220b. On the Danfoss EVB valve it is done by having an optimized shape of the moulded diaphragm, danfos reinforcement giving an internal damping and a special damping cone giving a viscous damping in the very late closing stage.
Learn more about our valve range in eev220b Danfoss Learning eLessons eLesson: Broad range of standard options EB is a range in a modular program. 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. For wv220b, oil, compressed air and similar neutral media Flow range from 0. 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 danfsos with an isolating diaphragm.
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.
Built-in pilot filter as standard, adjustable closing time and enclosures up to IP67 ensures optimal performance even under critical working conditions. Up to 10 bar Viscosity:
