Industrial Wafer Butterfly Valve
RSE Industrial wafer butterfly valve (≈40–45 in, ANSI ~125 class) featuring a ductile iron body, aluminum bronze disc, stainless steel (≈300 series) stem, and elastomer (e.g., Viton) seat. Weight ~800–950 lbs; ships via truck freight.
Key features:
- 3-point tongue-and-groove seat design supports moderate pressure ranges and full vacuum conditions
- Secondary shaft sealing minimizes leakage
- Two-piece shaft improves strength and flow performance
Additional:
Seat remains stable under elevated pressure differentials; center groove design reduces operating torque during cycling
