VF1-16 - Velocity Fuse
114 L/min (30 USgpm) • 210 bar (3000 psi)
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.
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 max-
imum mounting flexibility.
