Preventive maintenance with
valve purge compound
The use of valve purge compound 
(#6-460-B) between production shifts 
or after every eight hours of run time is
highly recommended. The compound
cleans any material residue from the
fluid path and conditions the valve for
future use.
1.  Install the barrel of valve purge
compound on the fluid-inlet fitting. 
2.  Apply reservoir pressure and cycle
the valve until the valve purge
compound has pushed all residual
material from the valve. Leave 
the compound in the valve until
future use.
3.  To remove the valve purge com-
pound, install material to be dis-
pensed and cycle valve until all
compound has been pushed from
the valve.
