General Information - Task Force Tips Ball Intake Valve AXD1ST-NX-T Instructions For Installation, Safe Operation And Maintenance

3.0 GENERAL INFORMATION

The Low Profi le Jumbo 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.
An electric remote controlled (RC) model allows the valve to be operated from a remote location. A typical installation will consist of
the RC valve and a remote display operator station. Motor controls are designed to auto sense 12 VDC or 24 VDC operation. The
motor control circuit utilizes a position encoder and current limiting to protect the drive train at the ends of travel. Unit is supplied
with 2' of cable with a plug on RC valve and 15' of cable with a receptacle so installation eff ort is minimized. Cable has only four
conductors (two for power and two for communications) further easing installation eff ort. To complete the installation, the installer
will need to mount and wire the remote display operator station. The display has 20' of cable. The power supply for the RC valve
will need to be connected to a protected circuit from the trucks power distribution center. Refer to the specifi cations Section 3.1 for
nominal current draw.
