Description

The Type 6228 is a servo-assisted 2/2-way solenoid valve with servo-diaphragm. It is particularly suited for neutral media.
Without electrical power, this solenoid valve is closed. Pressure builds up through the servo diaphragm,
which pushes the latter downwards and
thereby keeps the valve closed. On switching,
the space above the servo-diaphragm will
be
relieved via the pilot valve.
As a result, the pressure of the medium lifts
the servo-diaphragm, and the main valve opens.
A minimum differential pressure of 0.5 bar is
required for complete opening and closing.
The special design and geometry of the internal
parts of the valve produce a soft closing
function
with very low pressure peaks only.
