TABLE 1
AIR CONNECTIONS
NOTE
For quick response, Nexen recommends a quick exhaust valve and short air lines between the Control Valves and
the FMBES. Align the air inlet port to a down position to allow condensation to drain out of the Air Chamber of the
FMBES.
In high-cyclic applications, Nexen recommends a 50 ms delay between the solenoid valve and the motor starter.
