3.0 GENERAL INFORMATION

The Ball Intake Valve is intended for use on the intake manifold of a fire engine. The valve is kept closed while the water
supply from a hydrant or another pumper to the engine is being established. This prevents the pump from sucking air
through the intake manifold and losing its prime. Once the supply hose is filled and under pressure, and the air has been
vented from the hose, the valve may be opened to connect the pump to the water supply. An adjustable pressure relief
valve mounted on the bottom of the valve opens to relieve any excess pressure that may damage the hose or the pump.
The Task Force Tips Ball Inlet Valve has a unique patented half ball, with a
gate valve.

3.1 CORROSION

Hose couplings are attached using polymer bearing rings which provides electrical insulation to help prevent galvanic
corrosion. In the past some valves were made of bare aluminum. Task Force Tips is using a three-step process to fight
corrosion. The cast aluminum parts in this valve have been impregnated to fill the microscopic pores in the cast aluminum.
The parts are then hard anodized, and finally powder coated, inside and out, to help prevent corrosion. The effects of
corrosion can be minimized by good maintenance practice. See section 9.0 for maintenance.

3.2 USE WITH SALT WATER

Use with salt water is permissible provided valve is thoroughly cleaned with fresh water after each use. The service
life of the valve may be shortened due to the effects of corrosion and is not covered under warranty.

4.0 INSTALLATION

4.1 MOUNTING ON TRUCKS

Screw the large coupling to the pump inlet manifold. The valve position indicator should be clearly visible, but need not be
level.

grasp the small key on the shaft so it does not fall and get lost. Remove and
switch the two plastic bushings that come out of the sides of the gearbox. The
bushing with the large hole is installed on the same side as the handwheel.
Look through the gear box and note approximate position of the keyway in the
worm inside the gear box. Slide the shaft into the gearbox on the opposite side
of the gear box with the key oriented the same as the keyway. A small dab of
grease will keep the key place. Rotate the shaft until the key finds the keyway
and push the shaft in until it stops. Screw on the nut until it is 1/6 turn past

first nut, the crank will be hard to turn.

The handwheel is shipped from the factory on the

switched to the left hand side for convenience or if it
interferes with other equipment on the pump panel.
To move the hand wheel to the opposite side,
unscrew the jam nuts on the end of the shaft. Pull the
shaft out of the gear box. As the shaft is withdrawn,
