rotated counterclockwise or to the right from the valve position shown in fig1 similarly if valve member 30 were rotated clockwise or to the left from the valve position shown in fig1 it would be in a 34 left 34 open location as shown in fig7 sectantial cut 34a is adjacent and aligned with both ports 62 and 64 likewise secantial cut 34b is adjacent and aligned with both ports 60 and 66 as a result pressure flow is permitted between the supply input line and the control pressure line connected to passageway 56 and between the control pressure line connected to passageway 54 and the return pressure line the portion of valve member 30 spanning between lands 33a and 33b sealingly isolates pressure flow between pressure lines not directly connected by secantial cuts 34a and 34b in particular pressure flow between either the supply input line or the control pressure line connected to passageway 56 and the return pressure line or the control pressure line connected to passageway 54 is not permitted at this valve position on the other hand when valve member 30 is rotated to a 34 left 34 open location not shown secantial cut 34a is adjacent and aligned with both ports 60 and 64 secantial cut 34b is then adjacent.
