2026 Price Reference for Wafer Type Soft Seal Butterfly Valve DN65
As of 2026, the market price of a wafer type soft seal butterfly valve DN65 varies significantly based on body material, disc material, and actuation type. Based on current market data, manual lever-operated models generally range from RMB 180 to RMB 550 :
- Cast iron body models with standard galvanized discs and EPDM seals are the most economical option, typically priced in the RMB 180 to RMB 280 range. These are suitable for general water supply applications with moderate operating conditions .
- Ductile iron body models (QT450) offer improved strength and impact resistance, generally priced from RMB 260 to RMB 380. Ductile iron is a preferred material for municipal water supply due to its superior mechanical properties compared to standard cast iron .
Stainless steel body models (304 grade) provide enhanced corrosion resistance for more demanding water quality conditions or higher-purity requirements, priced in the RMB 450 to RMB 550 range .
For electric actuated versions, prices are substantially higher. A D971X-10Q DN65 electric wafer butterfly valve with a ductile iron body and rubber soft seal is listed at approximately RMB 1,180 . Another electric model, the D971X-16Z DN65 with a cast iron body, is priced around RMB 900 . A cast steel electric model (D971X-16C DN65) is listed at approximately RMB 690 .
It is important to note that these are reference prices. The final transaction cost depends on the specific material combination, pressure rating (PN10/PN16), connection standard, and brand. Bulk orders typically attract volume discounts.
Key Factors Influencing the Price of DN65 Wafer Soft Seal Butterfly Valves
Understanding what drives the cost of a wafer soft seal butterfly valve is essential for making an informed procurement decision.
Disc Material
The butterfly disc material significantly affects both corrosion resistance and price. Galvanized steel discs are the most economical, suitable for standard water supply applications . Stainless steel discs (304/316) offer superior corrosion resistance and can increase the valve price by 40% to 60% compared to galvanized alternatives . For drinking water applications, stainless steel discs are recommended to ensure water quality and long-term reliability.
Purchasing Recommendations for Water Supply Buyers
When sourcing a wafer type soft seal butterfly valve DN65 for water supply pipelines, follow these procurement guidelines.
Define your operating conditions precisely – Provide the supplier with the maximum operating pressure (PN10 or PN16), temperature, and water quality (potable, raw, or wastewater) to ensure the correct materials are selected .
Request multiple quotes – Prices vary significantly between suppliers based on material quality and brand. Obtain proposals from at least three professional valve manufacturers with your complete technical specifications .
Verify quality documentation – Ask for material test certificates, hydrostatic test reports, and relevant certifications to verify compliance with your specifications .
Consider lifecycle cost – While lower-priced valves may seem attractive initially, investing in higher-quality materials such as ductile iron bodies and stainless steel discs can significantly extend service life and reduce maintenance costs in water supply applications .
The wafer type soft seal butterfly valve DN65 is a proven solution for water supply pipelines, offering compact design, reliable shut-off, and cost-effective operation. As of 2026, prices for manual models range from approximately RMB 180 to RMB 550, while electric actuated versions range from RMB 690 to RMB 1,180. The final cost is determined by body material (cast iron, ductile iron, or stainless steel), disc material (galvanized or stainless steel), and actuation type (manual or electric).
When selecting this valve for water supply applications, pay careful attention to the pressure rating (PN10/PN16), material selection (ductile iron body + stainless steel disc + EPDM seal is recommended), and drinking water certification. For the most competitive and accurate pricing, contact manufacturers directly with your complete technical specifications and request multiple proposals to ensure both quality and value. Investing in a correctly specified wafer soft seal butterfly valve is an investment in the long-term reliability and efficiency of your water supply system.Do you still need to know or purchase the following Butterfly Valve products:
