Abstract
A non-magnetic latching servo actuated valve under the control of a controller comprising a motor in rotational communication with a lead screw. The lead screw advances or retracts a valve stem connected to a valve stem cap. The valve stem cap has a valve stem cap passage. A valve end cap having a valve seat is provided and receives the valve stem cap such that the valve stem cap can contact the valve seat. A pressure relief device or shuttle assembly is positioned internal to the valve stem cap. The shuttle assembly is used for venting build-up downstream pressure through the non-magnetic latching servo actuated valve outlet, through the valve stem cap passage, around the shuttle assembly, through passages, into a pressure chamber, and to the nonmagnetic latching servo actuated valve exit where the fluid vents until the system is in balance.
