Overview
This Hayward 3 inch butterfly valve combines robust thermoplastic construction with industrial-grade sealing for potable water, pool circulation, industrial process, and pneumatics applications. The valve features a PVC body with PVC disc, 316SS stem, and EPDM liner—a proven combination for chemical resistance and durability. EPDM seals provide reliable closure against acids, alcohols, and many aqueous solutions commonly found in municipal and industrial systems.
Key Features
- PVC body construction—lightweight yet rigid, resists corrosion better than metal equivalents
- PVC disc design for smooth, low-pressure-drop flow control
- One-piece 316SS stem ensures corrosion resistance and long service life
- EPDM liner and seals for broad chemical compatibility
- Wafer-body design fits ANSI 150 and PN10 flange patterns
- Lever handle with 19 lockable stop positions and 360° interlocking splines for precise flow control
- ISO 5211 mounting pad for optional actuator retrofit
- NSF/ANSI-61 and NSF/ANSI-372 listed (where applicable)
