Hose burst
When the lowering speed exceeds preset value, as it might happen
in case of hose failure, the flow is blocked. These valves should
ideally be screwed directly into the actuator outlet port. Sealing
parts are superfinished and enable to lock the load in the position
where the actuator is in the moment of hose failure. These valves
can be supplied, on request, with an orifice on the disc, allowing
an emergency lowering of the load. It is recommended to fit a flow
regulator valve downstream the hose burst valve, at the end of the
flexible hose, to control the lowering speed at the nominal value.
The “R” gap must be adjusted to allow a flow at least 50% over the
nominal regulated flow from the actuator.

The valve is only supposed to be operated in case
of hose failure. Should this circumstance occur, we
strongly recommend to verify the integrity of the
valve and eventually to replace it in the event that the
pressure spike generated by the hose failure was such
to damage permanently some valve components.
