1. A valve assembly, comprising: a body having an axis passing through a center of the body;a flow tube supported within and extending through said body, the flow tube being supported by a formed piece of sheet metal disposed between said body and said flow tube;a valve disposed within said flow tube and having an axle that is substantially perpendicular to said axis, said axle extending through and mounted for rotation relative to the flow tube; anda piston disposed in said body which is mechanically coupled to distal ends of said axle by two spaced-apart piston rods, said piston and said piston rods being mounted for rectilinear motion parallel to said axis;wherein said axle is offset from a plane which lies parallel to the axis and the axle, and which passes through the axis and both piston rods. 2. The valve assembly of claim 1 further comprising: a piston rod clevis disposed at one end of each of said piston rods. 3. The valve assembly of claim 2 further comprising: a link arm disposed between each of said piston rod clevises and the respective distal end of said axle. 4. The valve assembly of claim 3 wherein each of said distal ends of said axle has an axle crank arm extending therefrom and each of said link arms extends between one of the respective piston rod clevis and the respective axle crank arm. 5. The valve assembly of claim 4 further comprising: a sensor attached to said piston rod for detecting the position of said piston. 6. The valve assembly of claim 1 further comprising: an actuation cavity disposed between said body and said piston. 7. The valve assembly of claim 6 further comprising: a port attached to said body and in fluid communication with said actuation cavity.
