A first stage pressure regulator is provided. A valve body has an inlet and an outlet that define a pressure chamber therebetween. The valve body defines a pressure compensation chamber having an opening fluidly communicating the pressure compensation chamber with the surrounding water. The first stage pressure regulator comprises an inlet tubular union removably received into the inlet. A removable high pressure orifice body defines an orifice therethrough. The orifice body is carried by the valve body proximate the inlet. A valve seat is within the valve body.

1. A first stage pressure regulator comprising: a valve body having an inlet and an outlet and defining a pressure chamber between the inlet and the outlet, the valve body defining a pressure compensation chamber having an opening fluidly communicating the pressure compensation chamber with surrounding water;an inlet tubular union removably received into the inlet;a removable high pressure orifice body defining an orifice therethrough, the orifice body carried by the valve body proximate the inlet, the removable high pressure orifice body having a T-shaped head;a valve seat within the valve body;a valve member slidably carried within the valve body pressure chamber having a valve end, the valve seat being carried by the valve end, the valve member slidable between an open state in which the valve end carrying the valve seat is spaced from the removable high pressure orifice body permitting fluid flow through the orifice between the inlet and outlet and a closed state in which the valve end carrying the valve seat is sealingly seated against the removable high pressure orifice body preventing fluid flow between the inlet and outlet; andwherein the removable high pressure orifice body has an upstream end in the form of a T-shaped head having a larger diameter than a downstream end. 2. A first stage pressure regulator comprising: a valve body having an inlet and an outlet and defining a pressure chamber between the inlet and the outlet, the valve body defining a pressure compensation chamber having an opening fluidly communicating the pressure compensation chamber with surrounding water;an inlet tubular union removably received into the inlet;a removable high pressure orifice body defining an orifice therethrough, the orifice body carried by the valve body proximate the inlet, the removable high pressure orifice body having a T-shaped head;a valve seat within the valve body;a valve member slidably carried within the valve body pressure chamber having a valve end, the valve seat being carried by the valve end, the valve member slidable between an open state in which the valve end carrying the valve seat is spaced from the removable high pressure orifice body permitting fluid flow through the orifice between the inlet and outlet and a closed state in which the valve end carrying the valve seat is sealingly seated against the removable high pressure orifice body preventing fluid flow between the inlet and outlet; andwherein a bottom surface of the T-shaped head is seated upon outward facing surface of the inlet of the valve body; a top surface of the T-shaped head in contact with the inlet tubular union such that the inlet tubular union secures the orifice body in the inlet. 3. The first stage pressure regulator of claim 2, wherein the T-shaped head fits inside a cavity at a distal end of the inlet tubular union, and wherein the T-shaped head includes a slot that fluidly communicates a high pressure passage surrounding the T-shaped head with a center passage of the inlet tubular union; the high pressure passage in fluid communication with a high pressure exit port of the valve body. 4. The first stage pressure regulator of claim 1, wherein a head of the removable high pressure orifice body is inside a cavity formed in a distal end of the inlet tubular union. 5. A first stage pressure regulator comprising: a valve body having an inlet and an outlet and defining a pressure chamber between the inlet and the outlet, the valve body defining a pressure compensation chamber having an opening fluidly communicating the pressure compensation chamber with surrounding water;an inlet tubular union removably received into the inlet;a removable high pressure orifice body defining an orifice therethrough, the orifice body carried by the valve body proximate the inlet;a valve seat within the valve body;a valve member slidably carried within the valve body pressure chamber having a valve end, the valve seat being carried by the valve end, the valve member slidable between an open state in which the valve end carrying the valve seat is spaced from the removable high pressure orifice body permitting fluid flow through the orifice between the inlet and outlet and a closed state in which the valve end carrying the valve seat is sealingly seated against the removable high pressure orifice body preventing fluid flow between the inlet and outlet; andwherein a T-shaped head of the high pressure orifice body is dimensioned to fit within a cavity of the inlet tubular union. 6. The first stage pressure regulator of claim 5, wherein the orifice body is axially movable and the inlet tubular union limits axial motion of the orifice body. 7. The first stage pressure regulator of claim 1, wherein an end of the removable high pressure orifice body is in sealing contact with the valve seat in the closed state. 8. The first stage pressure regulator of claim 1, wherein the valve body comprises a material of a first hardness and the removable high pressure orifice is comprised of a material of a second hardness greater than the first hardness. 9. A first stage pressure regulator comprising: a valve body having an inlet and an outlet and defining a pressure chamber between the inlet and the outlet, the valve body defining a pressure compensation chamber having an opening fluidly communicating the pressure compensation chamber with surrounding water;an inlet tubular union removably received into the inlet;a removable high pressure orifice body defining an orifice therethrough, the orifice body carried by the valve body proximate the inlet;a valve seat within the valve body;a valve member slidably carried within the valve body pressure chamber having a valve end, the valve seat being carried by the valve end, the valve member slidable between an open state in which the valve end carrying the valve seat is spaced from the removable high pressure orifice body permitting fluid flow through the orifice between the inlet and outlet and a closed state in which the valve end carrying the valve seat is sealingly seated against the removable high pressure orifice body preventing fluid flow between the inlet and outlet; andwherein the removable high pressure orifice body generally includes: a T-shaped head at an upstream end; a conical protrusion at a downstream end; a slot formed into a top surface of the T-shaped head; an annular groove formed into the valve body proximate an axial center of the orifice body. 10. The first stage pressure regulator of claim 9, wherein the annular groove receives an O-ring; the O-ring in sealing contact with walls of the inlet of the valve body. 11. The first stage pressure regulator of claim 9, wherein the conical protrusion of the removable high pressure orifice terminates at a tip; the tip in sealing contact with the valve seat in the closed state. 12. A first stage pressure regulator comprising: a valve body having an inlet and an outlet and defining a pressure chamber between the inlet and the outlet, the valve body defining a pressure compensation chamber having an opening fluidly communicating the pressure compensation chamber with surrounding water;an inlet tubular union removably received into the inlet;a removable high pressure orifice body defining an orifice therethrough, the orifice body carried by the valve body proximate the inlet;a valve seat within the valve body;a valve member slidably carried within the valve body pressure chamber having a valve end, the valve seat being carried by the valve end, the valve member slidable between an open state in which the valve end carrying the valve seat is spaced from the removable high pressure orifice body permitting fluid flow through the orifice between the inlet and outlet and a closed state in which the valve end carrying the valve seat is sealingly seated against the removable high pressure orifice body preventing fluid flow between the inlet and outlet; andwherein the removable high pressure orifice is free of fastening threads. 13.
