Installation
E08 and E12 valves should be installed with reasonable accessibility
for service whenever possible. Keep pipe or tubing lengths to a
minimum with inside clean and free of dirt and chips. Pipe joint
compound should be used sparingly and applied only to the male
pipe — never into the female port. Do not use PTFE tape to seal
pipe joints — pieces have a tendency to break off and lodge inside
the unit, possibly causing malfunction. Care should be taken to
avoid undue strain on the valve.
Air applied to the valve must be filtered to realize maximum
component life.
Life Expectancy - Normal multi-million cycle life expectancy of
these valves is based on the use of properly filtered and lubricated
air at room temperature. These valves are also designed to operate
under non-lubricated conditions and will yield millions of
maintenance free cycles.
Factory Pre-Lubrication - Valves are pre-lubricated at
assembly with a petroleum based grease which has a lithium
content.
In-Service Lubrication - In-service lubrication is not required;
however, if lubrication is to be used, use an air line lubricant
(compatible with Nitrile & Polyurethane seals) which will readily
atomize and be of the medium aniline type. Aniline point range
must be between 180° and 220°F. Viscosity at 100°F:
140 - 170 SUS.
CAUTION: Do not use synthetic, reconstituted, or oils with
an alcohol content or detergent additive.
CAUTION: Do not restrict the inlet of valves having an
internal pilot supply. Pressure supply piping must be the
same size as the inlet port or larger to insure that the pilot
valve receives sufficient pressure supply during high flow
conditions.

WARNING
To avoid unpredictable system behavior that can cause personal injury
and property damage:
• Disconnect electrical supply (when necessary) before installation,
servicing, or conversion.
• Disconnect air supply and depressurize all air lines connected to
this product before installation, servicing, or conversion.
• Operate within the manufacturer’s specified pressure, temperature,
and other conditions listed in these instructions.
• Medium must be moisture-free if ambient temperature is below
freezing.
• Service according to procedures listed in these instructions.
• Installation, service, and conversion of these products must be
performed by knowledgeable personnel who understand how
pneumatic products are to be applied.
• After installation, servicing, or conversion, air and electrical supplies
(when necessary) should be connected and the product tested for
proper function and leakage. If audible leakage is present, or the
product does not operate properly, do not put into use.
• Warnings and specifications on the product should not be covered
by paint, etc. If masking is not possible, contact your local
representative for replacement labels.
