Nozzle Body and Nozzle Control Valve Installation: Nozzle Control Valve 2 (NCV2) Installation 31
NOZZLE BODY AND NOZZLE CONTROL VALVE INSTALLATION
NOZZLE CONTROL VALVE 2 (NCV2) INSTALLATION
1. Locate the Hawkeye® 2 NCVs and the O-rings provided with the kit.
NOTE: Hypro NCV2 and nozzle body will use the purple-colored (size 115) O-rings (P/N 219-2005-115)
Wilger NCV2 and nozzle body will use the black-colored (size 116) O-rings (P/N 219-2005-116)
2. Place the supplied O-ring on the inside of the fly nut flush with the valve body face.

3. Remove the diaphragm check valve from the threaded port of each nozzle body as needed.
4. Align the NCV2 with the port of the nozzle body while being careful not to lose the O-ring.
NOTE: On Wilger nozzle bodies, the NCV2 should always be located on the port closest to the wet boom
tube unless interferences do not allow this. This will create the least amount of stress on the nozzle
body and should allow satisfactory cable routing.
5. Turn the fly nut of the NCV2 to engage the threads of the nozzle body. Tighten until the NCV2 no longer
rotates freely.
NOTE: A leak test is recommended after the installation is complete.
BOOM CABLE ROUTING AND CONNECTION
BEST PRACTICES AND RECOMMENDATIONS
• Route the Hawkeye® 2 primary, mid, and outer boom cables along existing cables or plumbing to avoid cable
damage.
• Route cables to avoid pinch points and to avoid stretching the cable during folding and unfolding operations.
Pay special attention to cable routing near folding or break-away points.
• Route cables through existing cable retention devices as appropriate.
• When securing the primary, mid, and outer boom cables on the implement, begin at the outer boom tips.
Adjust the cable position to provide sufficient slack between valve tee branches while working toward the
center of the implement.
• Route the boom cables on the inside of the boom frame when possible.
• Secure cables using a zip tie at each nozzle control valve tee branch, and one between each tee branch along
the cable length.
