A control valve assembly includes a body having a first mud flow passage defining a mud flow inlet and one or more second mud flow passage portions. A magnetic plunger is slidingly mounted within the body. The magnetic plunger includes one or more third mud flow passage portions each including an inlet section and an outlet section configured to selectively align with the one or more second mud flow passage portions. A solenoid is mounted at the body. The solenoid is selectively activated to shift the magnetic plunger between a first position wherein the third mud flow passage portion is misaligned with the one or more second mudflow passage portions and a second position wherein the third mud flow passage portion aligns with the one or more second mud flow passage portions allowing a pulse of mud to flow through the mud flow passage.

A resource exploration system comprising: an uphole system; anda downhole system including a downhole string operatively connected to the uphole system, the downhole string including a pulser alternator generator having a main valve assembly, an alternator, and a control valve assembly operatively connected to the main valve assembly and the alternator, the control valve assembly comprising:a body including a first mud flow passage defining a mud flow inlet and one or more second mud flow passage portions, wherein the body includes a first body portion mechanically linked to a second body portion by a sleeve member, the first body portion including a central passage;a magnetic plunger slidingly mounted within the central passage of the body, the magnetic plunger including one or more third mud flow passage portions each including an inlet section and an outlet section configured to selectively align with the one or more second mud flow passage portions; anda solenoid mounted at the body, the solenoid being selectively activated to shift the magnetic plunger between a first position wherein the third mud flow passage portion is misaligned with the one or more second mudflow passage portions and a second position wherein the third mud flow passage portion aligns with the one or more second mud flow passage portions allowing a pulse of mud to flow through the mud flow passage. 12. The resource exploration system according to claim 11, further comprising: a mud flow sleeve arranged in the central passage, the one or more second passage portions being formed in the mud flow sleeve. 13. The resource exploration system according to claim 12, wherein the first body portion includes a fourth mud flow passage portion fluidically connected to the one or more second mud flow passage portions. 14. The resource exploration system according to claim 12, wherein the central passage includes an increased diameter portion defining a mud flow outlet chamber fluidically connected to the one or more second mud flow passage portions. 15. The resource exploration system according to claim 11, wherein the magnetic plunger is formed from diamond coated 9Cr. 16. The resource exploration system according to claim 11, wherein the second body portion includes a solenoid support and a solenoid carrier mounted to the solenoid support, the solenoid being carried by the solenoid carrier. 17. The resource exploration system according to claim 16, further comprising: a solenoid sleeve extending about the solenoid, the solenoid sleeve being formed from 9Cr. 18. The resource exploration system according to claim 16, wherein the magnetic plunger includes an actuating shaft slidably received by the solenoid carrier. 19. The resource exploration system according to claim 18, further comprising: a spring arranged between the actuating shaft and the solenoid support, the spring biasing the magnetic plunger toward one of the first and second positions. 20. The resource exploration system according to claim 11, wherein the one or more second mud flow passage portions includes at least two second mud flow passage portions and the one or more third mud flow passage portions includes at least two third mud flow passage portions.
