Nozzle Control Valve Maintenance Procedure - Raven Command FLEX II Calibration And Operation Manual

APPENDIX C

NOZZLE CONTROL VALVE MAINTENANCE PROCEDURE

AIM Command FLEX™ II nozzle control valves are designed to provide maintenance free operation with proper
equipment maintenance as recommended by the equipment or chemical manufacturer. However, the seals may
become worn or swollen due to chemical compounds, chemical formulations, or high operating pressures. This
may cause accelerated wear to the sealing surfaces. The following nozzle control valve maintenance procedures
should be performed on the nozzle control system or on individual NCVs if leaks are observed at a specific spray
tip.
