Air Valve Package
Numbers
Air valves generally open and close faster and are less prone to
error and component wear, making them suitable for industrial
use and other applications where the system will be constantly
running; however, they require a user-supplied pressurized air
source of 80 to 115 psi (5.5 to 7.9 bar).

8.3.1 Dual Air Valve
Installation
To install the air valve package (refer to Figure 8-3, 8-4, or 8-5,
depending on your pump model):
1. Position the valve bases 1.3 cm apart.
2. Use the plugs to stopper the ports which will not be connected.
DANGER
RISK OF INJURY. THE PRESSURE PRODUCED
COULD BE 700 BAR. PLEASE UTILIZE
