Construction
The Safety and Shut-off Block consists of a valve block,
a built-in pressure relief valve, a main shut-off valve,
and a man-ually operated bleed valve. In addition, an
optional solenoid operated bleed valve allows automatic
release of the accumu-lator or user unit and therefore
of the hydraulic system in an emergency or during shut-down.
The necessary return line connection is provided in
addition to the gauge connection.
