L4260-141 Series Double Lift-To-Turn Laboratory Gas Ball Valves, Panel, Wall & Overhead Mount

The WaterSaver Faucet Co.'s L4260 series laboratory ball valves have a spring-loaded handle that locks in the closed position. To open these valves, the user must lift while turning to unlock, a feature that prevents accidental activation. This safety feature is required for flammable gas service under certain plumbing codes (please check before ordering). These valves are designed for on/off control of natural gas only. 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.

This valve is available in two configurations:

• The L4260-141WSA 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 L4260-141FT 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 L4260-141SI is designed for installation in tight spaces with 2" depth such as fume hood walls. These valves have a side inlet connection, the opening for which can be specified in 15° increments to avoid obstructions in the wall cavity. These are available by special order only, and will have the current factory lead time which can typically range from 2 to 4 weeks. These configurations are non-returnable.

The valve body is forged brass with a polished chrome plated finish. 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". The L4260CV version includes an internal floating check to prevent back flow into gas system, and may be required under your local plumbing codes (please check before ordering).

NOTE: These valves are available for natural gas or other burning gas service only; use with other gases is not supported/recommended by WaterSaver. For use with other gases, select the L4200-141 series valves which are similar but lack the life-to-turn feature. To special order these valves for use with propane (black handle and a pink index button), please contact us.

Each unit is fully assembled and factory tested prior to shipment. 

Design and installation guidelines are available on-line. The specification drawings for the L4260-141WSA and L4260-141FT are available as PDF files.

Other mounting options include deck mounted (L4260-131 series), and panel-mounted single valves (L4260-158 series). The L4260 valve is also available singly.

FOR LABORATORY USE ONLY.
