AIR CONNECTIONS
4-WAY CONTROL VALVE
1. If the brake is to be set when the solenoid is de-energized,
connect the port marked 2 to the brake and the port marked
4 to the clutch (See Figure 4).
2. Connect the air supply line to the port marked 1 (See Figure
4).
5-WAY CONTROL VALVE
1. If the brake is to be set and the clutch is to be OFF when
the solenoid is de-energized, connect the port marked 4 to
the brake and the port marked 2 to the clutch (See Figure
5).
2. Connect the Brake air supply line to the port marked 5 and
the Clutch air pressure supply line to the port marked 3 (See
Figure 5).
3-WAY CONTROL VALVES
3-Way Normally Open (N.O.) and Normally Closed (N.C.)
Control Air Inlet Mounts
1. Install a 3-Way N.O. Control into the brake inlet port and a
3-Way N.C. Control into the clutch inlet port (See Figure
6).
2. Connect an air supply line to the inlet port (marked IN) on
top of the 3-Way N.O. Control and an air supply line to the
inlet port (marked IN) on the side of the 3-Way N.C. Control
(See Figure 6).
NOTE
When a 3-Way N.O. Control is de-energized, air flows
directly to the brake. When a 3-Way N.O. Control is
energized, air exhausts from the brake.
When a 3-Way N.C. Control is de-energized, air exhausts
from the clutch. When a 3-Way N.C. Control is energized,
air flows to the clutch.

NOTE
For quick response, Nexen recommends a quick exhaust valve and short air lines between the Control Valves and the
FMCBE. Align the air inlet ports to a down position to allow condensation to drain out of the air chambers.
