Product Description

The WaterSaver Faucet Co.'s L2870 series laboratory ball valves are designed for precise flow regulation of laboratory gases such as nitrogen, oxygen, helium and hydrogen. The valve is specially cleaned, lubricated and packaged for use with high purity gases at no extra charge.  Needle valves are for use with gases only.

The valve body is forged brass with a polished chrome plated finish. The valve unit features a floating tapered stainless steel needle and replaceable stainless steel seat. The valve goes from closed to open in 8 revolutions of the handle, providing precise flow regulation. The forged brass four-arm handle features a color-coded index disc (specify gas being used when ordering). The inlet and outlet are both 3/8" NPT female and the outlet has a removable ten-serration hose end that varies in diameter from ~1/2" down to 5/16". Each unit is fully assembled and factory tested prior to shipment.

The following configurations are available:

  • L2870 - Removable ten serration hose end
  • L2872 - Removable angle serrated hose end
  • L2873 - Quick connect fitting
  • L2874 - 1/4" O.D. compression fitting

The valve includes a plastic index disc indicating the type of service the valve is used for. Standard options include air, carbon dioxide, cold water, deionized water, distilled water, gas, hot water, hydrogen, nitrogen, oxygen, steam and vacuum (replacement buttons are available as item # Lbutton). Additional indexing options are also available.
