Abstract: Valve base module comprises a tank core passage extending within a plane containing a longitudinal axis, said plane oriented in non-perpendicular relation to a surface of said valve housing comprising at least a P, T, A, and B port and standard mounting holes for mounting said valve base module to at least one of a sub-plate or bar manifold. The plane is disposed at an offset angle ? relative to a second plane to permit one or more of at least P, T, A, and B ports to connect a first surface to an opposing second surface of the valve housing to form one or more of at least P?, T?, A?, and B? ports that permit the following additional modules to be mounted thereto: pilot control PCM, thermal insulating TIM, power supply PSM, pressure reducing PRM, diagnostic DM, load sense LSM, position feedback sensor PFSM, and manual override MOM.
