The smaller torsion springs will not return the flappers contained in the 4041RK1, 4041RK2, 4042RK1 and 4042RK2 kits to
a fully closed position if the valve is mounted vertically or upside down. Ensure that these mounting positions are avoided if
the smaller springs are used with the 4041RK1, 4041RK2, 4042RK1 and 4042RK2 kits.

1 Kits 4041RK1, 4041RK2, 4042RK1 and 4042RK2 contain 2 sets of shafts and springs. Swing check valves manufactured after March
2007 should use the larger axial shafts and larger torsion springs. Swing check valves manufactured prior to March 2007 will require the
use of the shorter axial shafts and the smaller torsion springs.
