Danfoss EV220B 15-50 Servo-Operated 2/2-Way Solenoid Valve

£55.74£928.25

The EV220B 15-50 is a universal indirect servo-operated 2/2-way solenoid valve programme.

The EV220B 15-50 is designed to minimise water hammer. The valve’s moulded diaphragm reinforces internal damping, and a special damping cone provides viscous damping in the very late closing stage. It also insensitive to dirt – a self cleaning coaxial filter in the main valve flow prevents dirt from entering the pilot system.

A number of coils, ranging all the way from 24Vac to 380-400Vac. 12Vdc and 24Vdc are also available. A range of cable plugs and accessories are also available to suit the coils.

The EV220B 15-50 is a universal indirect servo-operated 2/2-way solenoid valve programme.

To minimise water hammer, the valve’s moulded diaphragm reinforces internal damping, and a special damping cone provides viscous damping in the very late closing stage. The closing speed can be adjusted by changing the equalising force.

The EV220B 15-50 is also insensitive to dirt. A self-cleaning coaxial filter in the main valve flow prevents dirt from entering the pilot system. However, if the equalising orifice does become blocked, the dirt can be easily removed with compressed air.

With a range of materials available, there is an EV220B 15-50 valve suited for your application. The EV220B 15-50 is available in brass, dezincification resistant brass (DZR Brass) and stainless steel versions for aggressive steam applications.

The EPDM seals remain soft, even at -30ºC, while the FKM and NBR ribber seals can handle temperatures up to 140ºC.

The EV220B range uses the standard B-Rage of coils from IP00 to IP67. Coils subject to water splash and temperatures up to 80ºC should use the more powerful and robust clip-on coils.

The valve body has a smooth internal shape, and the specially designed diaphragm increases the lift height capacity. The moulded diaphragm has a built-in O-Ring to avoid leakage, as the pressure in the valve will increase the distance between the valve cover and the body. The O-Ring will eradicate this from happening.
