DISC INDICATION
VF-7 Series – Centric Butterfly Valve SelectionGuide
If installed between flanges ® Select VF-730 (Wafer Type)
Step 2: Dead-End Requirement
If single-side pipe removal is required ® Select VF-733 (Lug Type)
Step 3: Size and Application
For DN350 and above, or water works / pump stations ® Select VF-737 (Flanged Type)
**VF-730, VF-733 and VF-737 belong to the same Centric Butterfly Valve series.
Selection depends on installation method, pipe size and maintenance requirements.
