Patent number: 11867315Abstract: A method for verifying the operation of a safety valve having a valve member and a positioner for controlling the position of the valve member is proposed. The safety valve is part of a plant on which a process with a process medium runs. The plant has a sensor for monitoring the state of the plant, the process and the process medium. A sensor's measured value is used to determine a point in time during ongoing plant operation at which the operability of the valve can be verified in the context of a partial stroke test. The test can also be monitored with the sensor and the stroke range traversed therein can be dynamically adapted to the state. The test can thus be performed safely during operation and with an optimized stroke range. The method enables more frequent testing of and more reliable statements about the operability of the safety valve.Type: GrantFiled: March 3, 2021Date of Patent: January 9, 2024Assignee: SAMSON AKTIENGESELLSCHAFTInventor: Tobias Boll
