1. A valve comprising:
a valve cage having at least one groove and valve cage threads;
a first spring having a head held in position in the at least one groove of the valve cage and a foot;
a valve member having a periphery, a bottom surface, and a top surface with a trench holding the foot of the first spring securely in place in a position near the periphery of the valve member to help stabilize the valve member under operation;
a valve seat having a seating surface with a radius, valve seat threads that match the valve cage threads of the valve cage and upon threaded engagement secure the valve seat to the valve cage, and a channel located just below the valve seat threads; and
a locking ring installed in the channel of the valve seat, the locking ring securing the valve cage to the valve seat through mechanical deformation preventing the valve cage from backing off during service and serving as a seal and a barrier keeping debris and fine sediments from accumulating between the valve cage and the valve seat.
