Description

It’s a control interface for a shut-off valve, likely a ball valve or similar quarter-turn valve, featuring a visual indicator of its open (“On”) and closed (“Off”) positions, actuated by a manual key.

This device is used to safely and clearly control the flow of a fluid (liquid or gas) in various
industrial, commercial, or even specialized residential applications.
Safety: The clear ON/OFF indicators prevent confusion and reduce the risk of
accidents. The potentialfor a removable key adds a layer of safety for maintenance
work.
Reliable Control: It provides a direct, manual means for an operator to start or stop
fluid flow.
