The WaterSaver Faucet Co.'s L4100 series laboratory ball valves are 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). This valve is certified for gas service by the American Gas Association (AGA) and the Canadian Gas Association (CGA) and is recommended for ADA-compliant applications.
The valve body and handle are forged brass with a polished chrome plated finish. The valve unit features a quarter-turn open/close, a chrome-plated brass ball with molded TFE seals, and a color-coded index disc (specify gas being used when ordering). The inlet is 3/8" NPT male and the outlet has a non-removable seven-serration hose end that varies in diameter from ~1/2" down to 5/16". We generally recommend the L4200 valve which is identical except the hose end is removable, making the L4200 much more versatile than the L4100.
Each unit is fully assembled and factory tested prior to shipment. The L4100CV version includes an internal floating check to prevent back flow into gas system (the valve is not supplied in valves for vacuum service), and may be required under your local plumbing codes (please check before ordering).
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, and vacuum (replacement buttons are available as item # Lbutton). Additional indexing options are also available. If you select oxygen or hydrogen as your index button, the valve must be specially cleaned and the system will automatically add the fee for that to the price of the valve.
Note 1: Some jurisdictions require the use of the L4160 series valves for flammable gas use. The L4160 valve requires the user to lift the handle in order to turn it, preventing accidental activation. We do not have the L4160 permutations on-line, but if you need them, simply contact us. They are only a few dollars more than the L4100. For an example of what these look like, see the L4260 series valves.
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.
