Abstract
Various devices and techniques related to magnetically-actuated valves are generally described. Magnetically-actuated valves may include mechanisms to completely seal the valve during normal operation. However, mechanical access to the internal actuation mechanism may be temporarily provided in the event of a stuck valve. Access to a mechanical non-magnetically coupled portion of the internal actuation member may be provided for emergency access. The access to the internal actuation member is sealed off under normal operating conditions. A sealed port covers the portion of the internal actuation member during normal magnetically-coupled operation, but can be removed for direct mechanical access to the actuator. Furthermore, a backup seal may be sheltered within this port. The backup seal is typically not exposed to the outside environment or degradation, but prevents leaks during emergency actuation when access to the internal actuation member is temporarily provided.
