ABSTRACT:
A fluid pressure regulator capable of adjustably setting a cut-off pressure between an upper and a lower limit having a two-piece valve body where the two pieces are threadably joined such that adjusting the distance between the two pieces of the valve body moves a piston stem valve operating a high pressure port towards or away from the high pressure port while not changing the distance between the spring engaging the piston and the piston head.
