Tapered Bore Ring Spacer
are specially machined with a beveled inner diameter to accommodate butterfly valve discs. This ensures smooth operation, prevents disc interference, and maintains consistent flow performance, making them essential in valve-adjacent applications.
- Polypropylene (PP) – Cost-effective and lightweight
- PTFE (Teflon®) – Exceptional chemical and temperature resistance
- PVDF (Kynar®) – Flame resistant and UV stable with broad chemical compatibility
