The Danfoss EV220B 6-22 is a high performance, robust valve programme.
The EV220B 6-22 is the softest closing valve on the market. This design has an optimised diaphragm shape, added reinforcement for internal damping, and a special damping cone to ensure viscous damping in the critical late closing stage.
Also, the optimised diaphragm shape shape gives a very high lift height, providing excellent capacity and tightness at any pressure.
The EV220B 6-22 is insensitive to dirt. This is due to the square armature design enables the armature to move freely and reduces the risk of dirt particles lodging in the armature. If particles do lodge between the armature and the armature tube walls, they are quickly displaced by the fluid when the valve is activated.
As well as this, the EV220B 6-22 is available in two body materials. as well as this, the brass version is ideal for applications with a limited risk of corrosion. Tougher applications should use versions with dezincification resistant brass (DZR brass) bodies and stainless steel inserts.
Additionally, the EV220B range is compatible with the broad Danfoss B-Range of coils with enclosures from IP00 to IP67, including the clip-on system and specialty coils, making it easy to select a coil with the right features. The special ATEX coil programme is ideal for hazardous environments.
