In addition the closing speed can be adjusted by changing the equalising orifice. Go to the valve selector.
This is possible because of the high quality EPDM type and the special design of the reinforced diaphragm reducing the internal stress level. The program comes complete with the clip-on coil and IP65 electrical plug and has been carefully designed to simplify product selection. Spare parts kits for EVB.
Danfoss EVB Solenoid Valves
For water, oil, compressed air and similar neutral media Flow range from 0. The valve is designed with cast iron valve body and flanged connection. If this spring is very soft only a low differential pressure is needed to lift the diaphragm resulting in a high opening degree. This program is especially for OEM applications demanding a robust solution and moderate flow rates.
The filter is a self-cleaning type and is placed as a coaxial filter in the main valve flow.

This means you don’t need an assisted lift solenoid valve as in most of the cases. To avoid leakage because of the gap the moulded diaphragm has a built-in a-Ring giving an excellent sealing ddanfoss valve cover and valve body even at high pressures. Basic valve and coil theory eLesson: Water-hammer damped design and built-in pilot filter ensures a reliable operation. The valve is designed with very smooth internal shape of the valve body.

Material, media and market failures eLesson: EVB, servo-operated solenoid valves. Direct and indirect servo operated valves eLesson: High Pressure Water Pumps.
Built-in pilot filter as standard, adjustable closing time and enclosures up to IP67 ensures optimal performance even under critical working conditions. Broad range of different body and sealing materials The EVB range is available in three different body materials and with three different seal materials.
EV220B, servo-operated solenoid valves
This version is called EVB and can be used in contaminated ev220n that risk corrosion. Up to IP67 Flange connections: High capacity in the entire pressure range At low differential pressures an additional closing force is needed to get a proper tightness.
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. Broad range of standard options EB is a range in a modular program.
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. In reality the water hammer comes just before the valves closes. This is done by the closing spring. Direct operated solenoid valves eLesson: Valve body in brass, dezincification resistant brass and stainless steel ensures that a broad variety of application can be covered.
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. This results in a very good external tightness. For water and similar neutral media Flow range for water: For water, steam, oil, compressed air and gases Flow range for water: The seal material determines the minimum temperature.
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 the very late closing stage. Up to 10 bar Viscosity:
