A wafer butterfly valve is a compact, quarter-turn flow control device that fits between two pipe flanges and is secured by through-bolts. Its slim profile and light weight make it a practical choice for water supply, wastewater treatment, HVAC, and general industrial applications where space and cost matter.
This model features a ductile iron body, a CF8 stainless steel disc, and a replaceable EPDM rubber seat. The key advantage of this design is the field-replaceable seat: when the EPDM seat wears or loses its sealing properties, it can be removed and replaced without replacing the entire valve. This extends service life, reduces long-term maintenance costs, and simplifies spare parts management.
The valve is available with manual handle, gear operator, or actuator mounting (ISO 5211 top flange) to suit different operating requirements.
As a direct OEM/ODM manufacturer with over 19 years of export experience, Tianjin Worlds Valve Co., Ltd. customizes materials, sizes, pressure ratings, flange standards, coatings, and actuators to your exact specifications. Our products are exported to more than 50 countries and backed by ISO 9001:2015 certification (audited by LRQA), CE, UKCA, WRAS, and ACS certifications.

1. Replaceable EPDM Seat–Lower Maintenance Cost
Field-Replaceable–When the seat wears, it can be replaced in the field without removing the valve body from the pipeline.
Extended Valve Life–The body, disc, and stem remain in service while only the seat is replaced, reducing total cost of ownership.
Simplified Spare Parts–One seat fits all valves of the same size and model, simplifying inventory.
2. Body Material–Ductile Iron (DI)
Strength and Toughness–Ductile iron offers higher tensile strength and impact resistance than gray iron, suitable for general water and industrial service.
Corrosion Protection–Epoxy coating resists external corrosion in humid or buried conditions.
3. Disc Material–CF8 Stainless Steel (AISI 304)
Corrosion Resistance–CF8 provides good resistance to oxidation and corrosion in water, mild chemicals, and atmospheric exposure.
Durable and Lightweight–Offers good mechanical strength while keeping the disc weight manageable.
4. EPDM Seat–Reliable Sealing for Water and Wastewater
Water and Weather Resistance–EPDM is well-suited for water, steam, and outdoor applications.
Chemical Compatibility–Resists dilute acids, alkalis, and common water treatment chemicals.
Temperature Range–Typical EPDM service range is -20°C to +120°C, covering most municipal and industrial water applications.
5. ISO 5211 Top Flange–Ready for Automation
Standardized Interface–Accepts manual handle, gear operator, electric, pneumatic, or hydraulic actuators.
Easy Upgrade–Change actuation method without replacing the valve body.
