2026 Price Reference for Pneumatic Wafer Butterfly Valve DN80
As of 2026, the market price of a pneumatic wafer butterfly valve DN80 varies significantly based on material grade, actuator configuration, brand, and control accessories. Based on current market data, the price typically falls within the range of $120 to $800 USD per unit (approximately ¥870 to ¥5,800 RMB) .
- Economy-grade models with ductile iron or cast iron bodies, EPDM soft seals, and standard double-acting actuators are priced in the $120 to $250 USD range. A domestic brand D671J-10Q DN80 is listed at approximately ¥535 (about $74 USD) . A DN80 model from a German brand is priced at approximately ¥585 (about $81 USD) for the valve body alone, with the complete pneumatic actuator package at a higher cost .
- Mid-range models featuring stainless steel bodies (304 or 316), PTFE or FKM seals, and spring-return (single-acting) actuators range from $250 to $450 USD. A European supplier offers a DN80 pneumatic wafer butterfly valve with stainless steel disc and EPDM seal at approximately €425 (about $460 USD) excluding VAT . A professional manufacturer's KVD series DN80 with stainless steel components and pneumatic actuator is quoted in this range .
- Premium models with 316L stainless steel construction, explosion-proof actuators, and full accessory packages (solenoid valves, limit switches, positioners) can reach $500 to $800 USD or more . Imported brands or configurations with intelligent positioners and 4-20mA modulating control command the highest prices .
It is important to note that these are reference prices. The final cost depends on several factors including the specific material grade, actuator type (double-acting vs. spring-return), control accessories, and order quantity.
Key Factors Influencing the Price of DN80 Pneumatic Wafer Butterfly Valves
Understanding what drives the cost of a pneumatic wafer butterfly valve is essential for making an informed procurement decision.
Valve body and disc material is the most significant cost driver. Ductile iron bodies with epoxy coating are the most economical choice for general water and air applications . Stainless steel (CF8/304 or CF8M/316) offers superior corrosion resistance and is specified for chemical, food, and pharmaceutical applications, commanding a price premium of 50% to 100% over iron-bodied valves . For highly corrosive media, alloy or specialty plastic discs (such as PEEK) are available .
Seal material directly impacts both performance and cost. EPDM is the standard choice for water and mild chemicals, offering good temperature resistance up to 120°C . NBR provides excellent oil resistance but has a lower temperature limit of approximately 80°C . PTFE and FKM (Viton) offer superior chemical resistance and higher temperature capability (up to 180°C) but command higher prices .
Actuator type significantly influences the total package cost. Double-acting actuators are more economical and require air pressure for both opening and closing . Spring-return (single-acting) actuators are more expensive but provide fail-safe operation (spring-open or spring-close) in the event of air supply loss . Explosion-proof actuators add an additional premium for hazardous area installations .
Actuator configuration should be selected based on control requirements. Double-acting actuators are suitable for applications requiring both opening and closing under power. Spring-return actuators provide fail-safe positioning and are strongly recommended for safety-critical systems . Ensure the actuator sizing includes a minimum 30% safety margin above the valve's required torque .
Control accessories must align with the automation architecture. Specify solenoid valves with appropriate voltage (typically 24V DC or 110V AC) and manual override features . Limit switches or proximity sensors provide valve position feedback to the control system . For modulating control applications, an electro-pneumatic positioner with 4-20mA input/output is essential .
The pneumatic wafer butterfly valve DN80 is a proven solution for automation control systems, offering rapid response, seamless system integration, compact design, and reliable fail-safe operation. As of 2026, prices range from approximately $120 to $800 USD, with the final cost determined by body material (ductile iron, stainless steel), seal type (EPDM, NBR, PTFE, FKM), actuator configuration (double-acting vs. spring-return), and control accessories (positioners, limit switches, solenoid valves).
When selecting this valve for automation applications, pay careful attention to the actuator type and safety requirements, control signal compatibility, air supply specifications, and ISO 5211 mounting interface. For the most competitive and accurate pricing, contact manufacturers directly with your complete technical specifications and request detailed quotations including all necessary accessories. Investing in a correctly specified pneumatic wafer butterfly valve is not merely a purchase—it is an investment in the operational efficiency, safety, and reliability of your automated control system.
