The WaterSaver Faucet Co.'s L4200-158 series fixtures are designed for mounting on vertical surfaces such as walls, pipe chases, and service panels. They feature a single L4200 ball valve designed for on/off control of compatible laboratory gases, liquids, and vacuum at pressures up to 75 PSI. If needed, the valve 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. We stock both of these:
- The L4200-158WSA has a 3/8" IPS mounting shank, locknut and washer and is designed for installation were there is access behind the wall during installation.
- The L4200-158FT has a 3/8" NPT female inlet and is designed for installation 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.
A version with the valve body and outlet oriented 90° downward (parallel to the panel face) is available by special order as L4200-178WSA (please inquire). In all versions, 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.
Installation guidelines are available on-line. The specification drawings for the L4200-158WSA and L4200-158FT are available as PDF files.
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 # L4260-158.
Note 2: These valves are not for use with steam. For low-pressure steam valves see item # L2890.
Other mounting options include deck mounted (L4200-131 series), and wall/panel/overhead mounted (L4200-141 series).
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.
