The EV220B 6-22 is a high performance, robust valve
programme.
Low water hammer
The softest closing valve on the market, the EV220B 6-22
has an optimised diaphragm shape, added reinforcement
for internal damping, and a special damping cone to en-
sure viscous damping in the critical late closing stage.
Insensitive to dirt
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.
Broad range of body and sealing materials
The EV220B 6-22 is available in two body materials. 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 stain-
less steel inserts.
The EV220B 6-22 is also available with two seal materials.
Both the EPDM and FKM seals can cope with all common
media and a wide temperature range, while the EPDM ver-
sions have water approvals.
Long lifetime
The moulded rubber diaphragm has a special profile that
greatly reduces the effects of stress and maximises valve
lifetime.
Wide coil range
The valves use the standard B-range of coils from IP00
to IP67, including the clip-on system and specialty coils,
making it easy to select a coil with the right features. And
the special ATEX coil programme is ideal for hazardous
environments.
High capacity across the entire pressure range
The optimised diaphragm shape gives a very high lift
height, providing excellent capacity and tightness at any
pressure.
