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.

 

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.

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

• 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.

 

• 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.
