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 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. 

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.
