Introduction
Follow these instructions when installing, operating, or servicing
the product.
Application Limits
These products are intended for use in general-purpose compressed
air systems only. These units should not be used as shut-off valves,
as they do not shut off completely and must always be placed after
a shut-off valve.

Installation
The Auto-Pilot Soft Start valves should be installed with reasonable
accessibility for service and adjusting needle valve with a screwdriver.
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 valve.
Air applied to the valve must be filtered with a 40 micron filter 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, F442 oil is recommended. This
oil is specially formulated to provide peak performance and
maximum service life from all air operated equipment. Otherwise,
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.
Function
When pressure is supplied to the inlet port, gradual filling of the
downstream system occurs through the adjustable needle valve.
Upon reaching 70% of the supply pressure, the valve switches from
metered flow to full flow. The ramp up time to reach 70% of supply
pressure is adjustable via the needle valve in the cover
(See Figure 1).

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.
