Benefits

Adjust the pattern by extending the inner cores as a unit for horizontal flow or by retracting the cores for vertical flow.

The safety cable provided for neck sizes greater than 12” allows the inner core assembly to hang during maintenance work.

The VJR comes with three types of core adjustments—three position fixed, sliding, and rotating—for maximum flexibility.
