Maintenance
Clean Dispensing Valve and System Daily
NOTICE
Be sure that the solvent you use is compatible with the fluid being dispensed to avoid clogging the fluid pas- sages in the valve.
An important part of the care and maintenance of your automatic dispensing valve is proper flushing. Flush the valve daily with a compatible solvent until all traces of fluid are removed from the valve passages. Perform Pressure Relief Procedure, page 5 before flushing.
Clean the outside surfaces of the valve by wiping with a soft cloth dampened with a compatible solvent.
NOTICE
Never immerse the entire dispensing valve in solvent. Immersing in solvent removes lubricants and can damage packings.
To remove a hardened particle from the orifice, blow air through the orifice from the front.
Oil Dispensing Valve Daily
Before each use, lubricate with a spray of oil inside the protection tube (13) to prevent fluid buildup on these parts. Any buildup could damage the valve packings (16, 17, 18).
