MAINTENANCE
Precautions
|
| |
Automatic Valve products should be
serviced only by qualified and knowledgeable personnel
who understand the function and operation of the product.
Before servicing any pneumatic system, verify that the air and electrical power
are off and that all air within the system has been exhausted.
Take all necessary precautions to prevent degradation of products caused by stepping
on them, dropping them or hitting them with a hammer or other object.
Return products damaged as a result of improper handling to Automatic Valve for
inspection. |
|
Preventative Maintenance
|
| |
Install all pneumatic systems as described
in the “Installation” portion of this catalog. Improper
installation can cause sluggish system performance and,
if contaminates are not purged, premature wear of components.
Drain, clean, and service air line filters on a periodic basis or as recommended
by the manufacturer.
Adjust air line lubricators per the manufacturer’s recommendations (generally,
one drop per minute) and fill the reser-voir at scheduled intervals. When filling
the reservoir, use lubricating oils as prescribed under “Installation”.
To avoid possible solenoid malfunction, keep all electrical switches and relay
contacts in good condition.
Inspect mechanical actuators, such as cams and rollers, for signs of wear and
replace when necessary.
Automatic Valve products are designed to operate in normal air system environments
with a minimum of maintenance. In extreme conditions, as evidenced by sluggish
performance or sticking problems, a periodic program for cleaning internal product
components should be established.
To clean products, use a water soluble detergent.
To avoid component damage, do not use abrasive compounds or scrape
metal parts.

Servicing
|
| |
When servicing Automatic Valve products,
use only those components furnished in Automatic Valve
service kits. Items contained in these kits are designated
in the service portion of each catalog section or on
the drawing.
After a product has been disassembled, discard all items designated as service
kit items.
Clean remaining metallic components, except for solenoid coils and housings,
with a non-abrasive, water soluble detergent.
When reassembling the product, refer to the appropriate service section or the
drawing and lightly lubricate items, designated to be lubricated, to the drawing
instructions.
Test the product according to the drawing instructions. |

Precautions
|
| Read and follow the precautions listed
in the “Maintenance” section of this catalog. Stay clear
of all moving parts that must be actuated when troubleshooting. |

General Comments
|
Of all the components in an electrical/mechanical/pneumatic
system, it is most often the control valve that will
be faulted for system malfunction. In many cases, the
valve is only the symptom of the problem. Leaking cylinder
seals, poor electrical connectors, clogged air line filters,
and broken or jammed mechanical components are just a
few of the problems that can initially be diagnosed as
a valve problem.
Before disassembling any system component, use the following troubleshooting
guide to try to pinpoint the exact cause of the problem.
