Patent number: 11486515Abstract: For determining the operability of a fluid driven safety valve, a method comprising the following steps is described: A partial stroke test is performed on the safety valve, resulting in a stroke-pressure curve. The stroke pressure curve is extrapolated (330, 340) beyond the measured range (360) up to the safety closing position (350). From the extrapolated stroke-pressure curve, the closing pressure reserve (320) can be determined. In this way, the functionality of the safety valve can be checked during operation.Type: GrantFiled: February 14, 2019Date of Patent: November 1, 2022Assignee: SAMSON AKTIENGESELLSCHAFTInventor: David Wagner-Stuerz
