L2880-141 Series Standard Control Needle Gas Valves, Panel, Wall & Overhead Mount

The WaterSaver Faucet Co.'s L2880-141 series fixtures are designed for mounting overhead (undermount) or on vertical surfaces such as walls, pipe chases, and service panels. They feature two L2880 fine control needle valves designed for  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 unit features a floating tapered stainless steel needle and replaceable stainless steel seat. The valve affords good metering and can be ordered specially cleaned, lubricated and packaged for use with high purity gases (required for hydrogen and oxygen services). 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 to 250 psi (maximum working pressure is 150 psi) prior to shipment.

This valve is available in two configurations:

• The L2880-141WSA has a 3/8" IPS mounting shank, locknut and washer and is designed for installation on horizontal or vertical surfaces were there is access behind the wall during installation. The specification drawing is available.

• The L2880-141FT has a 3/8" NPT female inlet and is designed for installation on vertical surfaces where there is no access behind the wall during installation. The flange is threaded onto a nipple stubbed out from the wall and then the threaded escutcheon is then backed up to the wall to secure the valve and conceal the pipe. The specification drawing is available.

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

Installation guidelines are available on-line.

Additional mounting styles of needle valves are available but not all are listed on our web site. You can contact us for pricing or to order any of these other styles.

Tech note: Fine control needle valves which offer greater precision and operating pressures. The corresponding fine control valves (L2870 and L4870 series) are available to order directly.
