Setscrew Adjustment (Lever Free-Play)
IMPORTANT: This setting establishes the
amount of lever travel before the single-shot
mode-of-operation takes effect.
If the clearance is too great, the continuous
mode-of-operation can be lost. Not enough
clearance can prevent the valve from shutting
off.
The setscrew should be adjusted so a 1/16 " (1.5 mm)
clearance between the bottom of the hole on Lever (2) and
the surface of Extension (25) is achieved. See Figure 4.

(1.5 mm)
Figure 4 Lever Free-Play
This setting is the amount of lever free-play before
product begins to flow.
To set the clearance, adjust Setscrew (1) clockwise to
increase the amount of free-play or counterclockwise to
decrease the gap.
