The WaterSaver Faucet Co.'s L2870-131 series deck-mounted turrets feature your choice of one to four laboratory L2870 fine control needle valves 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 bodies are forged brass with a polished chrome plated finish. The valve units feature 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:
- L2870-131WSA - Turret with one L2870 valve.

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.
Installation guidelines are available on-line. The specification drawing for the L2870-131WSA is available as a PDF file.
