2026 Price Reference for Carbon Steel Flange Butterfly Valve DN250
As of 2026, the market price of a carbon steel flange butterfly valve DN250 varies significantly based on configuration, brand, pressure rating, and actuation type. The following reference ranges reflect current market data:
For a standard manual lever-operated model with a cast carbon steel body, flanged ends, and a rubber (EPDM/NBR) seat, prices typically start around 600 to 1,500 CNY per unit (excluding tax and freight) . This entry-level range covers basic configurations suitable for general water service with moderate operating conditions.
For worm-gear operated models from established brands, prices increase significantly. A Yuanda Valve D343H-10C DN250 (PN10, hard-sealed, carbon steel body) is priced at approximately 3,582 CNY per unit . A higher-pressure variant, the D343H-25C DN250 (PN25, hard-sealed), is listed at approximately 4,049 CNY per unit . For applications requiring expansion compensation, a telescopic butterfly valve model SD343H-6C DN250 is priced around 4,369 CNY .
For electric actuated models, prices are higher still. A Senke electric carbon steel butterfly valve DN250-PN16 is listed at approximately 2,500 CNY per unit. The wide variation in pricing reflects the diverse configurations available—different seal materials, pressure ratings, and actuation types all contribute to the final cost.
Body Material and Anti-Corrosion Treatment
The valve body is typically constructed from WCB cast carbon steel, which provides excellent mechanical strength and pressure resistance for water applications . For water treatment applications, additional corrosion protection is often required. Standard carbon steel can be upgraded with epoxy resin or PTFE linings to enhance corrosion resistance and extend service life. However, these anti-corrosion treatments typically add approximately 20% to 30%** to the base price . For standard water service without aggressive chemicals, unlined WCB construction offers the most cost-effective solution.
Why Carbon Steel Flange Butterfly Valves Excel in Water Treatment Engineering
The carbon steel flange butterfly valve offers several advantages that make it a first-choice solution for water treatment applications.
Robust and durable construction is a key benefit. WCB carbon steel provides excellent mechanical strength and pressure resistance, capable of handling the demands of water treatment systems . The flanged end design provides a secure, stable connection that is easy to install and maintain, making it ideal for large-scale infrastructure and municipal water systems .
Cost-effectiveness is another major advantage. Compared to stainless steel or alloy valves, carbon steel offers a lower upfront cost while delivering reliable performance for standard water service applications.
Versatility across multiple media types makes this valve a flexible solution. Carbon steel flange butterfly valves can handle fresh water, sewage, seawater, air, and other non-corrosive media .
Streamlined design and low-torque operation reduce energy loss and actuator requirements, contributing to overall system efficiency. The disc geometry enables tight shut-off and easy operation .
The carbon steel flange butterfly valve DN250 remains a cornerstone of water treatment engineering procurement, offering robust construction, reliable flow control, and cost-effective operation. As of 2026, prices range from approximately 600 to 1,500 CNY for basic manual models, with worm-gear operated branded valves such as the Yuanda D343H series priced around 3,582 to 4,049 CNY, and electric actuated versions starting at approximately 2,500 CNY . The final cost is determined by the pressure rating (PN10 to PN25), sealing material (rubber, PTFE, or hard-sealed), actuation type (manual, worm-gear, electric, or pneumatic), and brand certifications.
When selecting this valve for water treatment procurement, pay careful attention to the pressure rating, seat material compatibility with the fluid, flange standard alignment, and operating temperature. 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 the correctly specified carbon steel flange butterfly valve is an investment in the long-term reliability and efficiency of your water treatment operations.
