3.0 GENERAL INFORMATION
The Low Profi le Ball Intake Valve is intended for use on either the intake manifold of a fi re engine or on a discharge port of a fi re main.
The valve is available in versions to minimize interference with surrounding components. 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 fi lled 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 valve opens to
relieve any excess pressure that may damage the hose or the pump. The valve may be used for pressure or vacuum/drafting service.

3.2 CORROSION
Aluminum parts are hard anodized. All castings are then powder coated inside and out to help prevent corrosion. Hose couplings are
attached using polymer bearing rings which provide electrical insulation to help prevent galvanic corrosion. The effects of corrosion
can be minimized by good maintenance practice. See section 9.0 for MAINTENANCE.
3.3 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.
