The WaterSaver Faucet Co.'s L4200-141 series fixtures are designed for mounting overhead (undermount) or on vertical surfaces such as walls, pipe chases, and service panels. They feature two L4200 ball valves designed for on/off control of compatible laboratory gases, liquids, and vacuum at pressures up to 75 PSI. If needed, the valves may be specially cleaned, lubricated and packaged for pure gas service (tick the checkbox when ordering). These valves are certified for gas service by the American Gas Association (AGA) and the Canadian Gas Association (CGA) and are recommended for ADA-compliant applications.
This valve is available in two configurations:
- The L4200-141WSA 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 L4200-141FT 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 valve body and handle are forged brass with a polished chrome plated finish. The valve units features a quarter-turn open/close, a chrome-plated brass ball with molded TFE seals, and removable ten-serration hose end that varies in diameter from ~1/2" down to 5/16".
The valves also have 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, and vacuum (replacement buttons are available as item # Lbutton). Additional indexing options are also available. If you select hydrogen or oxygen as your index button, the valve(s) must be specially cleaned and the system will automatically add the fee for that to the price of the valve.
Each unit is fully assembled and factory tested prior to shipment.
Note 1: Some jurisdictions require the use of the L4260 series valves for flammable gas use. The L4260 valve requires the user to lift the handle in order to turn it, preventing accidental activation. The corresponding wall-mount fixtures are available under item # L4260-141.
Note 2: These valves are not for use with steam. For low-pressure steam valves see item # L2890.
FOR LABORATORY USE ONLY - These valves are not suitable for potable drinking water as they are made of brass which may have traces of lead.
