Maintenance

Clean Dispensing Valve and

System Daily

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.

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).

Service

Needle, Seat and Packings

To clean or replace the needle, its seat or packings (16,

17, 18), proceed as follows:

1. Perform Pressure Relief Procedure, page 5.

2. Remove valve housing:

a. Remove cap and spring.

b. Loosen nut.

c. Pull down housing and needle assembly to

expose needle shaft.

d. Slide needle through air piston to remove.

3. Remove RAC guard.

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.

NOTICE

Never immerse the entire dispensing valve in solvent.

Immersing in solvent removes lubricants and can

damage packings.
