Abstract:
1. A pressure regulator for controlling the flow of a pressurized fluid, the pressure regulator comprising: a housing having a proximal end, a distal end, and a plurality of chambers connecting at least one inlet channel to at least one out channel such that the pressurized fluid flows through the at least one inlet channel into the chambers and out of the chambers through the at least one outlet channel; a pressure-balanced valve assembly disposed within the housing, the valve assembly comprising: a valve actuator configured to simultaneously open both seals between the poppets and the seats; wherein the valve assembly is positioned so that when the seals between the poppets and the seats are closed, the pressurized fluid contacts and places under pressure a distal surface on the distal end of the first poppet, and a proximal surface on the proximal end of the second poppet, the force of the pressure on the distal surface of the first poppet being equal to the force of the pressure on the proximal surface of the second poppet; and wherein when the seals between the poppets and the seats are opened, the pressurized fluid flows outwardly across the knife edge of the first poppet into the first chamber; and inwardly across the knife edge of the second poppet into the second chamber.
