Metal Needle Valves are an adjustable method of flow control. Internally, the pin and body create an adjustable orifice that restricts flow. Useful for instances when the exact flow rate hasn't been determined or to compensate for flow variation in other parts of the system. Very fine threads ensure adjustment accuracy. A nylon insert in the threads increase the friction and reduce the likelihood of vibrations causing a change in the flow rate. All of the Air Logics products are assembled and tested in America.

Metal needle valves are tested for sealing and performance.

Barbed connections are a clean, time tested and cost efficient method of connection. The hoop strength of the tube holds around the barbed fitting. Air Logic's first barb is free of a parting line to create a good seal, additional barbs increase holding force for tube retention. Barbed connections are free of lubrication or thread sealant used in other styles of connection. Simply push the tube over the barb and the connection is complete.

Different barb sizes, mounting options and O-ring materials are available.
