Product Announcement from Beswick Engineering Co., Inc.

Beswick Engineering introduces additions to its growing line of miniature 10-32 threaded needle valves. Weighing about 10.5 grams in brass, the NVL series valves are an excellent choice for applications where precise flow adjustment is required in a very compact package.

Features & Specifications:

  • Capable of handling inlet pressures up to 500 psi.
  • The metal to metal seal provides positive shut-off down to 25 in Hg.
  • The standard valve has a 0.032" effective orifice when fully open. A high flow version is now also available, with an effective orifice of 0.059" when fully opened.
  • The needle valve allows precise flow adjustment due to 56 threads per inch adjustment and three degree taper of the needle. A higher resolution needle is also available.
  • The adjusted flow remains stable even during temperature fluctuations as the needle and valve seat are both manufactured from stainless steel.
  • The valve body (elbow or tee) swivels 360 degrees to facilitate installation and orientation.
  • The needle valve body is available with built-in-barbs which saves space and reduces cost of connections and assembly time.
  • O-ring seals throughout the valve insure a leak proof installation.
  • A cartridge body is also available for incorporation into manifold assemblies. Cartridge valves in concert with a manifold offer a smaller envelope, reduced assembly time and fewer parts.
  • New motorized version allows for greater flexibility and use in systems where computer control is essential.

Other Options:

  • Wide variety of outlet port configurations are available, including:
    • Barbs for 1/16", 5/64", 3/32", 1/8", and .170"-3/16" ID soft tubing
    • 10-32 threads (both internal and external)
    • Compression fittings for 1/8" OD stiff plastic or metal tubing
  • Adjustment options include screwdriver, knurled knob, hexagonal lock nut, or knurled lock nut.
  • Body material in brass, ENP brass, 303 stainless steel, or 316 stainless steel.
  • O-ring Seals in Buna-N, EPDM, Viton® or Silicone.

Applications Include:

  • Medical and dental equipment,
  • Instrumentation,
  • Ink jet printing,
  • Laboratory equipment,
  • Hydrogen fuel cells,
  • Semiconductor manufacturing equipment,
  • Aerospace,
  • Industrial robots,
  • And many more…
