1. A device for assembling and setting a cracking pressure of a valve, the device comprising: a chamber;an opening for receiving and mounting a valve body in the chamber, wherein the valve body receives a poppet comprising a shaft, a poppet spring positioned on the shaft, and a threaded spider positioned on the shaft between the poppet spring and a head of the poppet;an adjusting fork positioned in the chamber, and moveable through the valve body to engage the threaded spider, and draw the threaded spider into the valve body by rotating the adjusting fork, wherein the adjusting fork extends into the chamber through a second opening in the device, and a seal is positioned around an outer diameter of the adjusting fork adjacent the second opening. 2. The device as recited in claim 1, wherein the threaded spider compresses the poppet spring. 3. The device as recited in claim 1, wherein the chamber comprises an opening for receiving pressurized fluid into the chamber and the adjusting fork is rotated while the pressurized fluid flows into the chamber. 4. The device as recited in claim 1, wherein the threaded spider includes a plurality of legs protruding from the threaded spider, and the adjusting fork includes a plurality of slots for respectively receiving the plurality of legs. 5. The device as recited in claim 1, wherein the valve body includes threads positioned on an inner surface of the valve body, and the threaded spider includes threads positioned on an outer surface of the threaded spider that engage the threads of the valve body. 6. The device as recited in claim 1, wherein the poppet further comprises a guide spider positioned on the shaft between the poppet spring and a leading end of the poppet, the guide spider includes a plurality of legs protruding from the guide spider, and the adjusting fork includes a plurality of slots for respectively receiving the plurality of legs. 7. The device as recited in claim 1, wherein the adjusting fork includes an increased diameter portion having a diameter larger than a diameter of the second opening. 8. A method for assembling and adjusting a pressure setting of a valve, the method comprising: positioning a threaded spider and a poppet spring on a poppet;mounting a valve body into an assembly fixture;inserting the poppet including the threaded spider and the poppet spring positioned thereon into the mounted valve body;pushing an adjusting fork through an opening in the assembly fixture and through the valve body, wherein a seal is positioned around an outer diameter of the adjusting fork adjacent the opening;engaging the threaded spider with the adjusting fork; andflowing pressurized fluid into the assembly fixture while simultaneously rotating the adjusting fork in a direction to draw the threaded spider into the valve body and to compress the poppet spring. 9. The method according to claim 8, further comprising: measuring a relief pressure of a valve; anddrawing the adjusting fork out of the valve body and out of engagement with the threaded spider when a desired valve relief pressure is obtained. 10. The method according to claim 8, further comprising positioning a guide spider on the poppet prior to inserting the poppet into the mounted valve body. 11. The method according to claim 10, further comprising engaging legs of the guide spider with slots in the adjusting fork. 12. The method according to claim 8, wherein engaging the threaded spider with the adjusting fork includes inserting legs of the threaded spider into respective slots in the adjusting fork. 13. The method according to claim 8, further comprising flaring a leading end of the poppet. 14. The method according to claim 8, wherein the adjusting fork includes an increased diameter portion having a diameter larger than a diameter of the opening.
