The main cause of valves becoming stuck is when they are opened fully and left there. The correct way is to open them fully and then close them half a turn or so. This enables a little ‘wiggle’ room for the valve when it slowly becomes stuck again over the years. A valve stuck hard against the stops is very difficult to persuade to move again. On stuck valves I always use a
Mar 06 2020 To test that your stopcock is working try twisting the tap either way. Once you’ve shut the stopcock test your water flow.

Using an EVD on the other hand the actual ICP is measured intermittently. This is done by using a three way stopcock to close off the catheter towards the drainage system but to open the catheter towards a pressure transducer which then reads the pressure.
Stopcocks are types of ball valves used to control liquids or gas flow. PTFE stopcocks function in a manner similar to a ball valves but have a tighter seal when closed making them ideal for applications where vacuum and pressure will be used. Stopcocks for glass and rigid tubing have wetted parts constructed of PFA.
