[MW:29183] Re: Valve closer test

As per API598
Closure test:pressure test used to confirm leakage past or through a valve closure mechanism.
The closure test pressure obtained as follow:
-low pressure closure test 4-7 barg
-high pressure closure test=110% maximum allowable pressure
As you can see the closure test pressure is different from shall test pressure which is 150%MAWP.
Also, do a search forn FCI-20
