A reciprocating dual bellows assembly for high pressure valve applications, said dual bellows assembly comprising: a housing having a proximal end and a distal end, said housing having at least one inlet disposed adjacent said distal end; a pre-charge chamber having a first closed end disposed adjacent said proximal end and a second open end opposite said first closed end; an internal shaft being operably coupled to a system poppet assembly configured to alternatively seal and unseal an outlet in said distal end of said housing; a first bellows and a second bellows, wherein said first bellows has a first variable internal volume and includes a movable closed end and a fixed open end opposite said movable closed end, said fixed open end being operably and fluidly coupled to said second open end of said pre-charge chamber and said movable closed end being operably coupled to a first guide; wherein said pre-charge chamber and said first bellows are in fluid communication with each other to collectively form an extended pre-charge chamber at the proximal end of the housing, said extended pre-charge chamber being filled with a pressurized fluid set at a threshold pressure value; said second bellows has a second variable internal volume, and includes a movable back end operably coupled to a second guide and a fixed, open front end opposite said movable back end, wherein said fixed front end is positioned closer to said system poppet assembly and said movable back end is positioned farther from said system poppet assembly; wherein the reciprocating dual bellows assembly further comprises a fluid compression chamber operably disposed between said first guide and said second guide, said fluid compression chamber comprising a third internal volume that is filled with a substantially incompressible fluid to, in turn, operably connect said movable ends (840, 850) of both said first and second bellows (836, 846) to form a reciprocating guide assembly defined by said first guide, said second guide and said fluid compression chamber; wherein the substantially incompressible fluid in the fluid compression chamber surrounds the first bellows and the second bellows to exert pressure against the sides of those bellows; said internal shaft is operably connected to the second guide proximate said movable back end; and said at least one inlet enables a pressurized intake gas to enter said housing and flow through one or more access channels to exert a gas pressure against said movable back end of said second bellows. a housing having a proximal end and a distal end, said housing having at least one inlet disposed adjacent said distal end; a pre-charge chamber having a first closed end disposed adjacent said proximal end and a second open end opposite said first closed end; an internal shaft being operably coupled to a system poppet assembly configured to alternatively seal and unseal an outlet in said distal end of said housing; a first bellows and a second bellows, wherein said first bellows has a first variable internal volume and includes a movable closed end and a fixed open end opposite said movable closed end, said fixed open end being operably and fluidly coupled to said second open end of said pre-charge chamber and said movable closed end being operably coupled to a first guide; wherein said pre-charge chamber and said first bellows are in fluid communication with each other to collectively form an extended pre-charge chamber at the proximal end of the housing, said extended pre-charge chamber being filled with a pressurized fluid set at a threshold pressure value; said second bellows has a second variable internal volume, and includes a movable back end operably coupled to a second guide and a fixed, open front end opposite said movable back end, wherein said fixed front end is positioned closer to said system poppet assembly and said movable back end is positioned farther from said system poppet assembly; wherein the reciprocating dual bellows assembly further comprises a fluid compression chamber operably disposed between said first guide and said second guide, said fluid compression chamber comprising a third internal volume that is filled with a substantially incompressible fluid to, in turn, operably connect said movable ends (840, 850) of both said first and second bellows (836, 846) to form a reciprocating guide assembly defined by said first guide, said second guide and said fluid compression chamber; wherein the substantially incompressible fluid in the fluid compression chamber surrounds the first bellows and the second bellows to exert pressure against the sides of those bellows; said internal shaft is operably connected to the second guide proximate said movable back end; and said at least one inlet enables a pressurized intake gas to enter said housing and flow through one or more access channels to exert a gas pressure against said movable back end of said second bellows.
