description A valve assembly (30) with coupled seats includes a first body (34) with a first annular valve seat (72) and a pin bore (33) centered about an axis (90). A second body (32) is attached to the first body (34) and has a second annular valve seat (73) centered about the axis (90) and located in a position opposite to the first annular valve seat (72). A ball (36) is positioned to move between the annular valve seats (72,73). A pin (35) is mounted to move in the pin bore (33) along the axis (90) such that one end can contact the ball (36) to move the same. The pin bore (33) along with the annular valve seats (72,73) are coupled by providing one of the first body (34) and the second body (32) with a locating bore (91) centered on the axis (90). The other of the first body (34) and the second body (32) has a cylindrical portion (92) substantially parallel to the axis (90) and sized to be tightly received in the locating bore (91). The valve assembly (30) was developed for use with a solenoid (31) as a control valve in a fuel injector (4).
