It's actually a type of clamp used to install or remove valve springs in auto engines .
To install a compression valve, first turn off the water supply. Next, use a wrench to disconnect the old valve. Slide the compression nut and ferrule onto the pipe, then insert the new valve. Tighten the compression nut securely and turn the water supply back on to test for leaks.
A compression test will show you if you have a burned valve.

With a wrench carefully holding back on the valve body
close it with a valve wrench, change the o-ring
Valve sticking, Burnt or broken valve, or bad valve seat could all be the problem. Be sure to check leakdown compression at 15-20 degrees PAST top dead center! Compression release is still engaged at TDC!
Check the compression of the cylinders you will have a low reading in the one with a bad valve
Yes, a tight exhaust valve can cause compression issues in an engine. If the valve does not close fully or remains slightly open when it should be closed, it can lead to a loss of compression, allowing combustion gases to escape during the compression stroke. This results in reduced engine power, poor fuel efficiency, and increased emissions. Proper valve adjustment is crucial for optimal engine performance.
Do a compression test.
You don't repair compression rings you replace them.
Your engine will probably missfire and you will not have compression in the cylinder that has the broken valve spring because your valve will stay open.
