A valve system and method is disclosed that includes, in one preferred embodiment, a compact valve system (10) that may be configured in many different ways so as to be especially suitable for conforming to the dimensional requirements of many particular subsea installations such as lower riser packages. Thus, the height of the hydraulic actuator (16, 18) and/or manual override operators (62, 64) can be varied depending on the necessary configuration. The valve body (36) is preferably symmetrical such that the position of the hydraulic actuator (16, 18) and manual override operator (62,64) could be switched, if desired.
