| Systems and methods for maintaining operation of gas sampling equipment utilized in oil and gas operations, wherein an isolation valve is deployed along a gas extraction conduit in order to isolate a gas analysis system from pressurized fluid that may be injected into the extraction conduit from a fluid delivery system. A parameter of the flow stream, such as a particular gas content or the presence of a bump gas, may be monitored. A change in the parameter may be indicative that debris is inhibiting fluid flow into the extraction conduit. When such a condition is suspected, gas sampling is suspended and the valve between the gas analysis system and the intake of the extraction conduit is closed. With the valve closed in order to protect the gas analysis system, a fluid is injected into the extraction conduit from the fluid delivery system. | ||||||

| A magnetic holding brake (1) having at least one turning brake member (4) allocatable to a rotatable part (2) of an actuator (3) and a fixed brake member (6) allocatable to a torque-proof part (5) of the actuator (3). The turning brake member (4) and the fixed brake member (6) each at least have one permanent magnet (7, 8) of different polarity. The permanent magnets are lying opposite to each other in a pre-defined relative position of the turning brake member (4) and the fixed brake member (6) under exertion of a braking or holding torque. In this manner, the possibility exists that a holding in the so-called “fail as is”-mode is more easily and reliably and at the same time cost-efficiently achievable without wear or further energy demand. | ||||||
