CMS Lockable Line Valve
CMS Lockable Line Valve
Lockable line valves are the means of isolation within the medical gas pipeline outside AVSU areas. They are used at branch take-offs and upstream of main equipment, and are locked in position to prevent unintended operation.
What is it?
The valve is supplied with ends suited to brazing onto medical copper tube, in a range of sizes covering branches and mains, with a locking mechanism fixing the open or closed position. NIST variants are available for test or temporary connection points per the approved design.
