GG Interlocks For Wheel Operated Valves

Discontinuation of Ellis interlocks

Sofis has discontinued the Ellis line of interlocks effective in December of 2018. The Ellis chain lock will continue to be produced, as well as spare keys.

The Sofis brands, Smith Flow control, and Netherlocks are our leading interlock lines that include the latest developments to suit all interlock requirements.

Please consult a Sofis representative to understand how we can replace your current Ellis locks with a Sofis interlock system.
