<p>A pressure control device and associated method of use capable of regulating fluid pressure for multiple fluid types. The pressure control device includes a fluid sensing port (83), a pressure responsive device (80), a valve (88), a valve seat (82), a first valve chamber (89), a second valve chamber (91) that is moveable in relationship to the first valve chamber, a first member (85) located within the first valve chamber, a first biasing mechanism (84) located between the pressure responsive device (80) and the first member (85) , a first adjustment mechanism (87) adjustably attached to the first valve chamber for selectively positioning the first member (85) in relation to the first valve chamber, a second member (90) located within the second valve chamber, a second biasing mechanism (103) to apply pressure to the second member and a second adjustment mechanism (97) adjustably attached to the second valve chamber for selectively positioning the second member (95) in relation to the second valve chamber.</p> |
