A pressure regulator includes a pressurized fluid, direct-drive, balanced dual poppet valve assembly that requires no dynamic seals and is pressure balanced. Each poppet has a knife edge that creates a bubble-tight seal against a cooperating seat. The sealing knife edge of one poppet faces into the pressure, and the sealing knife edge of the other poppet faces away from the pressure. The pressure balance negates performance impact of high or low fluid pressure. Furthermore, the design provides for a controlled depth of deformation by the sealing knife ed...
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 first seat cartridge comprising a first seat;a first po...
