Broad range of different body 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.

To avoid danfosd 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. The seal material determines the minimum temperature. Valve body in brass, dezincification resistant brass and stainless steel ensures that a broad variety of application can be covered.

This means you don’t need an assisted lift solenoid valve as in most of the cases. The filter is a self-cleaning type and is placed as a coaxial filter in the main valve flow. In reality dancoss water hammer comes just before the valves closes.

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

Home EVB series Solenoid valves. Learn more about our valve range in the Danfoss Learning eLessons eLesson: The valve is designed with very smooth internal shape of the valve body.

Spare parts kits for EVB. This is done by the closing spring. If this spring is very soft only a low differential pressure is needed canfoss lift the diaphragm resulting in a high opening degree.

EV220B, servo-operated solenoid valves

Up to IP67 Flange connections: High capacity in the entire pressure range At low differential danfsos an additional closing force is needed to get a proper tightness. For water, oil, compressed air and similar neutral media Flow range from 0.

Why not open an account? Direct and indirect servo operated valves eLesson: This version is called EVB and can be used in contaminated media that risk corrosion.

Insensitive to dirt The flow through the dirt sensitive pilot system is filtered on the EVB. 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.

The valve is designed with cast iron valve body and flanged connection. They are available normally closed or normally open. This makes it possible to choose the optimal coils no matter if the ‘solution be technical or economical.

This program is especially for OEM applications demanding a robust solution and moderate flow rates.

For water and dxnfoss neutral media Flow range for water: Direct operated solenoid valves eLesson: On the EVB there are no compromises on the capacity of the valve. 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. Danfoss EVB water hammer damped solenoid valve In general it is the closing speed of the valve that determines the water hammer phenomenon.

In addition the closing speed can be adjusted by changing the equalising orifice. During the movement of the diaphragm the rubber is stressed and relieved several times and often determines the lifetime of the valve. Built-in pilot filter as standard, adjustable closing time and enclosures up to IP67 ensures optimal performance even under critical working conditions.

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 Danfosss version with FKM and optionally with an isolating diaphragm. Go to the valve selector. For water, steam, oil, compressed air and gases Flow range for water: High Pressure Water Pumps.

Danfoss EVB Solenoid Valves

Up to IP67 Thread connections: Broad range of standard options EB is a range in a modular program. Good external tightness even at high differential pressures The pressure in the valve tries to increase the gap between valve cover and valve body.

This is possible because of the high quality EPDM type and the special design of the reinforced diaphragm reducing the internal stress level. 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. The program comes complete with the clip-on coil and IP65 electrical plug and has been carefully designed to simplify product selection.

Also the use of a special design of the diaphragm to e2v20b its lift height increases the capacity.

Up to 10 bar Viscosity: 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. Up to 50 cSt Coil enclosure: Due to the increased thickness on the sealing point of the diaphragm of danfosss EVB valve only a very low closing force is needed from the spring.
