Line
and board assembly. Models 32, 75 and 125.
Sizes: 3/8”, 3/4” NPT and 1”1/4
BSPT.
Commanded retention valves are hydraulically
blocked and are supplied in two versions:
connection with a screw for line assembly
on the hydraulic pipe and board assembly according
to CETOP standards. These valves grant unidirectional
retention valves the possibility to unblock
them and allow a free flow by means of an
external pilot. At rest, the retention float
is closed by means of a constant-pressure
coil, thus sending pressure to the piloting.
Said pilot is activated on top of the retention
float enabling free flow. There are two kinds
of retention floats: in the first case, simple
float with decompression. The piloting pressure
must be 40% of the blocked pressure. In the
case of the float with decompression, the
piloting pressure should not exceed 10% of
the blocked pressure.
- Oil-flow block in one sense.
- Enables backward flow in the same sense,
where the hydraulic pilot is activated
