The valve is designed with very smooth internal shape of the valve body. Good external tightness even at high differential pressures The pressure in the valve tries to increase the gap between valve cover and valve body. They are available normally closed fanfoss normally open. Material, media and market failures eLesson: This is possible because of the high quality EPDM type and the special design of the reinforced diaphragm reducing the internal stress level.

High Pressure Water Pumps. Learn more about our valve range in the Danfoss Rv220b eLessons eLesson: Up to IP67 Thread connections: Spare parts kits for EVB. This means you don’t need an assisted lift solenoid valve as in most of the cases.

Danfoss EVB ( series) Servo-operated 2/2-way solenoid valves

If the equalising orifice is blocked by build-up of dirt, it can easily be removed and cleaned with compressed air. Built-in pilot filter as standard, adjustable closing time and enclosures up to IP67 ensures optimal performance even under critical working conditions. Find the dsnfoss 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.

Basic valve and coil theory eLesson: If this spring is very soft only a low differential pressure is needed to lift the diaphragm resulting in a high dafnoss degree. The valve is designed with cast iron valve body and flanged connection.

Accessories such as isolating diaphragm unit, NO-unit, manual-operating unit and adjustable equalising orifice are easily fitted dantoss the valve, and the usual wide coil range can be used. The seal material determines the minimum temperature.

This program is especially for OEM applications demanding a robust solution and moderate flow rates. Up to IP67 Flange connections: Broad range of standard options EB is a range in a modular program.

This results in a very good external tightness. By controlling the closing speed at this stage the water hammer can be reduced. 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.

On xanfoss Danfoss EVB valve it is done by having dsnfoss 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. Due to the increased thickness on the sealing eg220b of the diaphragm of the EVB valve only a very low closing force is needed from the spring. For water and similar neutral media Flow range for water: Direct operated solenoid valves eLesson: The filter is a self-cleaning type and is placed as a coaxial filter in the main valve flow.

Broad range of different body and sealing materials The EVB range is available in three different body materials and with three different seal materials. This makes it possible to use the EVB for’ several brines.

Go e2v20b the valve selector. 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. Water-hammer damped design and built-in pilot filter ensures a reliable operation. On the EVB there are no compromises on the capacity of the valve.

For water, steam, oil, compressed air and gases Flow range for water: Wide coil range up to IP This makes it possible to choose the optimal coils no matter if the ‘solution be technical or economical.

Direct and indirect servo operated valves eLesson: For water, dancoss, compressed air and similar neutral media Flow range from 0.

Insensitive to dirt The flow through the dirt sensitive pilot system is filtered on the EVB. Up to 50 cSt Coil enclosure: Up to 10 bar Viscosity: In addition the closing speed can be adjusted by changing the equalising orifice.

Why not open an account? Home EVB series Solenoid valves. This is done by the closing spring. Danfoss EVB water hammer damped solenoid valve In general it is the closing speed of the valve that determines the water hammer phenomenon.

During the movement of the diaphragm the rubber is stressed and relieved several times and often determines the lifetime of the valve. Also the use of a special design of the diaphragm to increase its lift height increases the capacity. In reality the water hammer comes just before the valves closes.

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. Valve body in brass, dezincification resistant brass and stainless steel ensures that a broad variety of application can be covered.
