EVB, servo-operated solenoid valves. Material, media and market failures eLesson: Water-hammer damped design and built-in pilot ev22b0 ensures a reliable operation. This makes it possible to use the EVB for’ several brines.

For water, steam, oil, compressed air and gases Flow range for water: Home EVB series Solenoid valves. 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. Good external tightness even at high differential pressures The pressure in the valve tries to increase the gap between valve cover and valve body.

Up to IP67 Flange connections: 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.

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

Danfoss EVB Solenoid Valves

The valve is designed with cast iron valve body and flanged connection. In addition the closing speed can be adjusted by changing the equalising orifice. Danfoss EVB water hammer damped solenoid valve In general it is the closing speed of the valve that determines the water hammer phenomenon.

On the EVB there are no compromises on the capacity of the valve. Broad range of different body and sealing materials The EVB range is available in three different body materials and with three different seal materials. By controlling the closing speed at this stage the water hammer can be reduced. Up to IP67 Thread connections: Spare parts kits for EVB. Also the use of a special design of the diaphragm to increase its lift height increases the capacity.

Broad range of standard options EB is a range in a modular program. During the movement of the diaphragm the rubber is stressed and relieved several times and often determines the lifetime of the valve. Dznfoss capacity in the entire pressure range At low differential pressures an additional closing force is needed to get a proper tightness.

Wide coil range up to IP This makes it possible to choose the optimal coils no matter if the ‘solution be technical or economical. The filter is a self-cleaning type and is placed as a coaxial filter in the main valve flow.

Direct operated solenoid valves eLesson: Go to the valve selector. Basic valve and coil theory eLesson: The seal material determines the minimum temperature. 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.

For water and similar neutral media Flow range for water: 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 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. 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.

This is done by the closing spring.

Direct and indirect servo operated valves eLesson: If the equalising orifice is blocked by build-up of dirt, it can easily be removed and cleaned with compressed air. This means you don’t need an assisted lift solenoid valve as in most of the cases.

Due to the increased thickness on the sealing point of the diaphragm of the EVB valve only a very ev2200b closing force is needed from the spring.
