please carry out the safety checks:
- Make sure you, and everyone around you are
wearing safety goggles
- Remove any paintballs from your
marker
- Point the marker in a SAFE direction and
visually, then mechanically check that there are no paintballs in
the marker
- Detach the power supply (air or C02 source) and

Description
The DART Quick Exhaust Valve (Q.E.V) is a
diaphragm operated tri-directional hosing elbow capable of being
used in a number of applications. The elbow is sensitive to flow
direction, switching the resulting direction of flow depending on
the input direction. It is used most commonly in applications where
performance increases can be made by exhausting a chamber as fast
as possible. By truncating the exhaust channel (the air may exhaust
at the elbow, negating the requirement for it to back flow along
small bore hosing) removes the distance that air must flow in order
to be fully exhausted, thus removing the length and severity of
obstructions.
The Q.E.V is male threaded 10/32" on one end, and
on the other end of the 90 degree fitting, there is a nipple
designed to take 1/8" External Diameter low pressure hosing. The
Q.E.V had been used to excellent effect on a number of paintball
markers. Most commonly QEV's are used on
44 Magnum Rams.
Prerequisites
The fitting of this part requires a MODERATE
degree of competency in mechanical work. If you are unsure as to
your skill level as an airsmith we recommend that you seek
professional advice or services from a qualified
airsmith.
Required tools and
spare parts
To fit this part you will require some or all of
the following tools:
- Dentists pick or similar
- Q Tip and solvent / cleaning solution
- 10mm size Spanner (For attachment of
Q.E.V)
- 5mm sized Spanner (For removal of
nipple)
- Weak thread locking compound
Removal of Part
- If the Q.E.V is being used to replace a single
nipple, carefully remove the current nipple with the 5mm spanner.
If much resistance is met, DO NOT FORCE. There is a danger of
rounding off the flat on a barb fitting as the metal is often quite
soft. Instead, use a blow torch or heat gun to loosen the thread
locking compound used to seal the barb. BE CAREFUL OF ANY
SURROUNDING PLASTIC PARTS OR O RINGS when heating the
barb.
- Clean out the threaded hole into which the Q.E.V
will be inserted. Be sure to remove any old thread lock compound,
grease, oil etc using a solvent and a Q tip.
Installation of
Part
- Pour out a small amount of thread lock compound
onto a disposable non-absorbent surface (such as some kitchen
foil). Using the fine end of a pick or a needle, place a TINY
amount of compound in a single stripe down an edge of the threads.
Rotate the threads 180 degrees and add another TINY
stripe.
- Using the 10mm spanner, GENTLY screw the Q.E.V
into position and the correct orientation. BEWARE that the threads
are very small and consequently not very strong. Any attempt to
over tighten the Q.E.V will result in stripping the threads, or
more likely, the Q.E.V snapping and becoming irreparably damaged.
If correct sealing methods are used then the parts need not be
tightened hard.
- Wait the specified curing time for the thread
seal compound to set.
- Push hosing onto barbed end of Q.E.V using soft
jawed pliers
Notes
- Be very careful when screwing in QEV's as the
item is small and too much leverage (for example using a long
spanner) can easily break them.
