The fine threads of the needle valve permit excellent adjustment for precise control of flow. The flow is restricted in both directions and is adjustable from 0 to the equivalent flow of a 0.025" diameter orifice. The 7-turn adjustment needle valves are available in two models, the standard model and the fine adjustment model. The standard adjustment model has a pin angle of 6 degrees with 10-64 threads; the fine adjustment model has a pin angle of 4 degrees with 10-80 threads.

The valve body is phosphor bronze and can be supplied with straight ports for 1/16" i.d. tubing or with barbs for 1/16", 1/8", or 3/16" i.d. tubing. The pin is beryllium copper and can be supplied with a Buna-N, EPDM, or Viton o'ring. All pins have a nylon vibration insert. Valves for inline or panel-mounted applications are available.
