a
re leak free, poppet type solenoid
cartridges in screw-in execution normally
used to cut off the hydraulic power supply
l
ine. They are available in normally closed
N
C, or normally open one NO configurations.
T
he /FV version integrates an inductive
p
osition switch (double contact NC/NO)
쩹 wich supplies the output electrical on-
off signal indicating the poppet 쩸 position
(
open/closed), and therefore they can be
u
sed as safety valves for emergency
conditions.
T
hey are CE marked and certified by TÜV
in accordance with safety requirements of
Machine Directive 2006/42/CE.

INSTALLATION NOTES
1) The assembling of cartridges inside manifolds must be done tightening the valve exagonal ring (for tightening torque, see section 쪮).
E
xcessive values can cause anomalous deformation and poppet sticking.
For the /FV versions avoid to tighten through the position sensor.
2) The CE certification is valid only with shielded electric cables and connector. Consult also tab. P004.
These safety valves must be supplied only and always as one complete component, proximity sensor is factory adjusted.
The supply of subcomponents invalidates the certification.

SIGNAL
According the criteria of safety specifications, the poppet position signal must change its status
inside the overlapping stroke (before the effective valve opening).
