7.6 CONFIGURABLE ORIENTATION OF COMPONENTS
The valve inlet can be mounted either at the bottom of the valve (facing down), or on the side of the valve (facing any orientation with the
inlet axis horizontal). The chosen inlet direction will affect the required orientation of the valve gearbox and the required location of the
pneumatic cylinder.
Table 7.6 lists 9 configurations of inlet orientation and gearbox orientation that will allow proper operation of the valve with a counter-
clockwise opening direction of the valve per NFPA. The valve is supplied in configuration 1 by default.
To use this table:
First choose the Roman numeral subheading (I through V) that describes the directions the hand-wheel and inlet will face relative to the
truck. Then, choose the configuration number (1 through 9) that describes the desired side of the truck the handwheel and gearbox will
face. The four columns to the right will be referenced in the assembly instructions
and Figure 8.2A Valve Components.
Additional guidelines applicable to the configurations of Table 7.6:
1. For simplicity, this table assumes a hand-wheel on the left side of the truck, as noted by a single asterisk (*). For a handwheel on
the right side of the truck, the gearbox must face the opposite front/rear direction from what is shown in the table. This will
maintain the required counter-clockwise handwheel rotation to open the valve.
2. Configuration 8 (noted **) has the gearbox facing forward when the inlet is on the left side.
3. Configuration 9 (noted ***) has the gearbox facing rearward when the inlet is on the left side.
4. As viewed from the outlet end of the device, the pneumatic cylinder must always be mounted approximately 180° from the valve
gearbox to allow clearance for the telescoping stroke. This 180° can be infinitely adjusted ±30° as needed, with the exception for
a side inlet that the pneumatic cylinder can only be biased away from the inlet, not towards it.
5. When universal joints are used to extend the valve driveshaft, it is not necessary for the valve inlet to be perfectly parallel/
perpendicular to the handwheel axis. This allows infinite adjustment of the side inlet orientation, within angle limits provided by the
universal joint manufacturer.
6. Dual handwheels on both the side and top of the truck can be applied to any of the 9 configurations with the addition of a right-
angle bevel/miter gearbox that allows a through-shaft connection.
