Aluminum Alloy Ventilation Butterfly Valve DN200 Price – Designed for Dust Collection and Ventilation Systems
2026 Price Reference for Aluminum Alloy Ventilation Butterfly Valve DN200
As of 2026, the market price for an Aluminum Alloy Ventilation Butterfly Valve DN200 used in dust collection and ventilation systems typically falls within the range of approximately $20 to $60 USD per unit (roughly 140 to 430 RMB). This price range reflects the various configurations, sealing options, and manufacturing processes available in the market.The main Butterfly Valve product names of China Butterfly Valve Network include:Electric Soft-sealed Wafer Butterfly Valve,Electric Single Eccentric Wafer Butterfly Valve,Electric Soft-sealed Flange Butterfly Valve,Electric Speed Control Butterfly Valve,Electric Vacuum Butterfly Valve,Electric Ventilation Butterfly Valve,Electric Serrate Regulate Butterfly Valve,Extended Hard-sealed Flange Butterfly Valve.
For a standard manual lever-operated model with soft sealing (such as EPDM rubber) and a 2mm body thickness, prices generally start at the lower end of this spectrum, typically around **$20 to $35 USD**. These basic models are suitable for general-purpose ventilation applications with clean air or mildly dusty environments and offer excellent value for money.
For worm-gear operated versions or models with hard sealing (metal-to-metal) , prices tend to be higher, ranging from $35 to $60 USD. Hard-sealed valves are designed for higher temperatures and more demanding service conditions where a rubber seal would degrade prematurely.
Several factors influence the final price you will pay for an aluminum alloy ventilation butterfly valve DN200:
Body thickness – Valves with a 4mm body thickness offer higher durability and a longer service life compared to 2mm versions, but come at a higher cost.
Seal type – Soft sealing (EPDM rubber) is typically more affordable, while hard sealing (metal-to-metal) costs more but handles higher temperatures.
Brand and manufacturing process – Well-known brands or precision-cast valves sit at the higher end of the price range.
Order quantity – Bulk purchases can significantly reduce the unit price, making large-scale Actuation type – Manual lever operation is the most economical, while worm-gear operators, electric actuators, and pneumatic actuators add progressively more to the unit cost.
Why Aluminum Alloy is the Preferred Material for Ventilation and Dust Collection
Aluminum alloy offers a unique set of properties that make it exceptionally well-suited for ventilation and dust collection applications.
Lightweight construction is perhaps the most significant advantage. Aluminum alloy valves are substantially lighter than their cast iron or steel counterparts, making them easier to install, especially in overhead ductwork or confined spaces. This weight reduction also translates to lower support structure requirements and reduced installation labor costs.
Corrosion resistance is another critical benefit. Aluminum alloy performs well in dusty, humid, or mildly corrosive air streams, providing long-term reliability without the rust and degradation issues that plague carbon steel valves in similar environments. The material naturally forms a protective oxide layer that resists atmospheric corrosion, making it ideal for ventilation systems exposed to varying humidity levels.
Anti-condensation properties are particularly valuable in HVAC applications. Aluminum alloy butterfly valves, often referred to as "anti-condensation valves," effectively prevent surface condensation when temperature differentials exist between the duct interior and the surrounding environment. This feature is especially important in air conditioning water systems where condensation can lead to corrosion, dripping, and system inefficiency.
Fast operation is another key advantage. The 90-degree rotation mechanism allows for quick opening and closing, enabling rapid flow adjustment and system response. This is particularly valuable in dust collection systems where pressure drops and flow rates must be adjusted frequently to maintain optimal collection efficiency.
Key Selection Parameters for DN200 Aluminum Alloy Ventilation Butterfly ValvesWhen specifying an aluminum alloy ventilation butterfly valve DN200 for your dust collection or ventilation system, several critical parameters must be considered to ensure proper selection and long-term reliability.
Pressure Rating and Temperature Limits
The standard pressure rating for aluminum alloy butterfly valves in the DN200 size is typically PN10 (1.0 MPa) to PN16 (1.6 MPa) , with some models available up to higher ratings. It is essential to match the valve's pressure rating to your system's maximum operating pressure, including any transient surges.
Temperature is another critical limiting factor. For standard soft-sealed models with EPDM rubber seats, the applicable temperature range is typically up to 80°C. For higher temperature applications requiring metal-to-metal sealing, hard-sealed valves can handle more elevated temperatures. For ventilation systems handling hot flue gases or exhaust streams, verify the valve's temperature rating against your operating conditions.
Body and Disc Materials
The valve body is typically constructed from die-cast aluminum alloy (such as ADC12), which provides excellent strength-to-weight ratio and corrosion resistance. The disc (butterfly plate) can be manufactured from various materials depending on the application:
Nylon 11 – Offers good wear resistance and is suitable for general ventilation.
304 or 316 stainless steel – Provides superior corrosion resistance and is recommended for more aggressive environments.
High molecular polymer materials– Offer excellent sealing performance and wear resistance.
The Aluminum Alloy Ventilation Butterfly Valve DN200 represents an excellent solution for dust collection and ventilation systems, offering outstanding lightweight construction, corrosion resistance, anti-condensation properties, and reliable flow control. As of 2026, prices range from approximately $20 to $60 USD per unit, with the final cost determined by body thickness, seal type (soft vs. hard), brand, actuation method, and order quantity.
When selecting this valve, pay careful attention to pressure ratings (PN10-PN16), temperature limits (typically up to 80°C for soft-sealed models), sealing material compatibility (EPDM, NBR, or metal-to-metal), connection standards, and actuation requirements to ensure a perfect match for your application.
