Product Description

The WaterSaver Faucet Co.'s L4200 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 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 L4200CV 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 following configurations are available. The L4200 and L4200CV are stock items; the other configurations ship from the factory:

  • L4200/L4200CV - Removable ten serration hose end (see item # BO140S-G).
  • L4202/L4202CV - Removable angle serrated hose end (see item # BO142).
  • L4203/L4203CV - Quick connect fitting (see item # BO191).
  • L4204/L4204CV - 1/4" O.D. compression fitting (see item # BO183).

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 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.

Installation guidelines are available on-line. The specification drawings for the L4200 and L4200CV 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.

Note 2: These valves are not for use with steam. For low-pressure steam valves see item # L2890.

A wide variety of mounting options are available including deck-mounted turrets (L4200-131 series), wall mounted (L4200-158 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.
