VF1-10/VF11-10 - Velocity Fuse
23 L/min (6 USgpm) • Up to 350 bar (5000 psi)
Operation
This valve is normally open
from port 1 to port 2. When
flow exceeds the setting of
the valve, it closes. The valve
returns to the open condition
when the pressure at port 1 is
reduced to less than 80 psi.
Features
Hardened and ground and
honed working components.
Cartridge construction for
maximum mounting flexibility.
Description
This is a screw in cartridge
velocity fuse used to lock a
cylinder or motor in place in
the case of a complete hose
failure.
