LINE SHUT-OFF VALVE
P/N 260-9921
GENERAL INFORMATION:
This valve can be used as a brake shut-off. When energized, the valve will block
pressure from reaching downstream. The valve does not prevent fluid from returning to
the master cylinder. This eliminates the possibility of trapping pressure when activating
the valve.
INSTALLATION INSTRUCTIONS:
Mounting/Routing: Position the brake shut-off valve between the master cylinder and
the caliper to be shut-off. Mount securely with the bleed screw in the up position utilizing
the mounting slots in the bracket using two mounting screws (not provided). The in/out
brake shut-off ports are 1/8-27 NPT threads. An adapter may be required from the port
fittings of the unit (included) to the brake line tubing depending upon the application.
Run a brake line from the master cylinder to the “IN” port of the brake shut-off. Run
another line from the “OUT" port of the brake shut-off to the caliper you want to control.
The brake shut-off may be bled through the top bleed screw if necessary.
Wiring: The lead wires should be connected to a 12 volt, 5 amp (recommended) fused
power source through a toggle switch. Always be sure to switch off the power to the
line shut-off when the unit is not needed
