Ductile Iron Butterfly Valve Series

MDS specializes in manufacturing ductile iron butterfly valves that meet standards EN 593 / ISO 5752 / BS 5155 / AWWA C504, with sizes ranging from 2″ to 48″. Available in multiple configurations, our factory-direct valves offer unbeatable factory prices. Each valve body is made of premium ductile iron, combined with advanced sealing structures and precision machining to ensure reliable sealing performance and extended service life.

Product Types

• Wafer Type Butterfly Valve
  Ideal for pipe line wafer installation, featuring EPDM or NBR seals for corrosion and wear resistance. Compact and lightweight design.

• U Type Butterfly Valve
  Valve disc edged with a U-shaped polymer seal ring for zero leakage, low operating torque, smooth opening/closing, and minimal maintenance.

• Lug Type Butterfly Valve
  Improved wafer design with threaded lugs for one-side removal without disconnecting the pipeline. Perfect for end-of-line or intermediate installations.

• Double Flange Butterfly Valve
  Integral flanged ends for direct connection to pipeline flanges. High pressure rating suitable for large-diameter and high-pressure systems.

• Actuated Butterfly Valve
  Can be fitted with electric or pneumatic actuators for remote and automated control—ideal for industrial automation and centralized systems.

• Double Flanged Eccentric Butterfly Valve
  Double-flanged, eccentric design minimizes friction and ensures even wear of sealing surfaces. Suited for high-temperature, high-pressure, or particulated media.

Key Advantages

• Factory-Direct Pricing: Own casting and machining facilities eliminate middlemen for more competitive quotes.

• Strict Quality Control: Every valve undergoes pressure, leakage, and torque testing to ensure ready-to-install reliability.

• Customizable Options: Supports special sizes, actuators, coatings, and materials to meet your project requirements.

• Fast Delivery: Streamlined production and ample stock of standard models; non‑standard orders available in as fast as 30 days.

Typical Applications

• Water & Wastewater: City water supply, sewage treatment, pump station control

• HVAC: Central air-conditioning cooling and hot water circulation

• Industrial Pipelines: Chemical, food processing, paper, power generation

• Automation: Remote intelligent valve regulation and interlock control
