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.

A contamination-free pyrovalve having first tubing section and a second tubing section. The first and second tubing sections are disposed in spaced-apart relation such that a conveying path between the first and second tubing section is established. An opening is disposed between the first and second tubing sections. A valve body is fixedly attached to the first and second tubing sections. The valve body has a bore. A ram is disposed inside the bore of the valve body. A slug is disposed in the opening between the first tubing section and the second tubing section. The slug is held in position by a frictional fit. A combustion chamber is disposed in operative relation to the ram such that when an explosive material is ignited the pressure inside the chamber causes the ram to move through the bore to strike the slug and to displace it from the opening between the first and second tubing sections such that the valve is opened.
