NOTE
For reciprocating valves the adjustable link turnbuckle must be parallel to the valve stem. To
ensure linearity in positioning verify that the hole in the lever aligns with the indicating hole in
the bracket when the valve is in the closed position. Check that the bracket is mounted on the
correct holes. (See Figure 39 for details).
