- Quarter-turn operation
- Good for general-purpose use
- Available in various materials (PP, PVC, stainless)
- Standard 2" and 3" outlet sizes
Butterfly Valves
- Good for viscous materials
- Lower profile design
- Easy to clean
- Higher flow rates
Camlock Fittings
- Quick-connect capability
- Popular in transfer operations
- Available in multiple materials
- Industry standard connection
Material Considerations
Polypropylene (PP)
Standard for most applications. Good chemical resistance, food-safe options available.
PVDF/Kynar
Superior chemical resistance for aggressive chemicals.
Stainless Steel
Durable, easy to clean, ideal for food and pharmaceutical applications.
Gasket Materials
- EPDM: General purpose, good for many chemicals
- Viton: Excellent chemical resistance
- PTFE: Broadest chemical compatibility
- Silicone: Food-grade applications
Maintenance Tips
- Replace gaskets showing wear
- Lubricate threads periodically
- Store with valve closed but not over-tightened
- Inspect for cracks or damage regularly
