Stroke Control Reference
The Stroke Control Reference feature is used
to calibrate the stroke control setting or doc-
ument the dispensing process.
To calibrate the valve, the stroke control
knob is first closed all the way. The set
screw is then loosened and the stroke ref-
erence ring turned so that the zero on the
reference ring is aligned with one of the two
reference marks engraved on the valve body.
When the set screw is tightened, the valve is
calibrated.
Tamper Resist Option
Any 740V Series valve can be ordered in the
tamper resist configuration to limit unautho-
rized adjustment.
In -TR configuration, stroke adjustment can
only be made when a special stroke control
knob is inserted into the stroke mechanism.
A kit can also be ordered as a retrofit for
existing valves.
