components of module 18 in the embodiment shown valve stem 130 and valve portion 132 are shown as constructed of titanium material it is to be understood that any suitable material may be employed moreover it is to be understand that valve stem 130 at its most distal end could include a silicon covering or the like in order to insure a full closure of the valve if desired likewise while o ring 124 as shown as being constructed of a silicon material any other suitable material may be employed for instance teflon may be employed as can a material known as poron u00ae in operation fluid dispelled from chamber 30 under pressure provided by chamber 36 travels through both exits 46 and 48 the fluid dispelled through exit 48 is preferably directed into contact with first pressure sensor 82 so a pressure reading of the fluid within chamber 30 can be taken the fluid dispelled through exit 46 preferably first travels through a filter and capillary construction as are known in the art in one example of such a structure a filter and capillary are coiled around an underside of upper portion 32 fluid flows through the filter which is designed to prevent particulates and other undesirable matter of flowing into the capillary and thereafter flows through the capillary which is essentially a very small tube with a small diameter that allows a maximum flow rate of fluid therethrough that fluid then flows through aperture 106 a and into the passages provided in valve block 86 second pressure sensor 84 takes a pressure reading of the fluid within the valve block once within valve block 86 the fluid flows into contact with the distal end of valve stem 130 depending upon the positioning.
