DN200 lever butterfly valve

In industrial piping systems, choosing the right valve not only affects operational efficiency but also determines long-term maintenance costs. Especially for large pipelines like DN200, you might be considering several types of valves: gate valves, ball valves, or automated control valves. However, if your system doesn’t require remote control and needs a simple, durable, and cost-effective open/close solution, the DN200 lever butterfly valve is an option worth considering.

This valve stands out for its compact design, quick operation, reasonable price, and easy maintenance. At Bao Tin Steel, we supply a full range of genuine DN200 valves from brands like Wonil and YDK, ready to meet the demands of projects big and small. Explore detailed specifications and practical applications below!

Design and Appearance

The DN200 lever butterfly valve typically has a flat, slim profile, optimizing installation space. Its exterior color varies depending on the material and protective coating. Common valve body types include Wafer (clamp style), Lug (with bolt ears), and Flanged, each suited to different connection requirements and system stability. The sealing gasket is usually black or white, lined inside the valve body to ensure a tight seal.

The valve body can be made from cast iron (gray iron or ductile iron) coated with blue or red epoxy for general applications such as clean water, wastewater, and fire protection systems. For environments requiring high corrosion resistance or food-grade safety, stainless steel (SUS 304 or SUS 316) is used. The valve disc is usually stainless steel, and the sealing gasket is carefully selected from EPDM, NBR, PTFE (Teflon), or Viton to suit the temperature and chemical properties of the fluid.

Basic Technical Specifications

The DN200 lever butterfly valve is a manually operated, quick-opening valve, typically installed in pipelines with an outer diameter of 219mm. Featuring a wafer design, the valve is clamped between two flanges using bolts, allowing for easy installation, removal, and maintenance.

Here are the typical basic specifications for a DN200 lever butterfly valve:

• Size: DN200 (φ219mm, 8 inch)
• Body material: Ductile iron, Stainless steel (SUS304, SUS316), Plastic (PVC, UPVC)
• Disc material: Ductile iron, Stainless steel (SUS304, SUS316, 420), Aluminium bronze
• Sealing material: EPDM, NBR, PTFE (Teflon)
• Connection type: Wafer, Flanged
• Connection standards: JIS, BS, ANSI, DIN
• Working pressure: PN10, PN16 (10 kg/cm², 16 kg/cm²)
• Working temperature: Depending on the material, typically -15°C to 180°C (up to 350°C with certain special seals)
• Application environment: Water, wastewater, oil, gas, steam, chemicals
• Origin: Korea (Wonil, YDK), Malaysia (AUT), China, Taiwan

Some high-end models can withstand temperatures up to 120°C when equipped with PTFE seals, making them suitable for steam or light chemical applications.

Outstanding Advantages of DN200 Lever Butterfly Valves

The DN200 lever-operated butterfly valve is popular not only for its reasonable cost but also for its practical advantages in industrial and domestic piping systems. Key highlights that make this product widely trusted include:

• Compact Design: The valve is smaller and lighter compared to many other valves of the same diameter, saving installation space and simplifying transportation.
• Quick Operation: A simple 90° turn of the lever fully opens or closes the valve.
• Cost-Effective: Compared to other types of valves, lever-operated butterfly valves are generally more competitively priced, especially models with ductile iron bodies.
• Material Flexibility: Available in a variety of body, disc, and seal materials, allowing selection for diverse working environments such as clean water, wastewater, chemicals, air, or steam.
• Easy Maintenance: Cleaning, lubrication, and replacement of worn parts are straightforward and time-efficient.

Practical Applications of DN200 Lever Butterfly Valves

The DN200 lever-operated butterfly valve is widely used across various industrial and domestic sectors, including:

• Water Supply and Drainage Systems: Installed in water treatment plants, municipal water supply, and wastewater treatment systems.
• HVAC Systems: Regulates flow in air conditioning and ventilation systems.
• Chemical Industry: Suitable for handling chemicals, acids, and alkalis, depending on the valve materials.
• Food and Beverage Industry: Stainless steel valves ensure hygiene and safety standards.
• Fire Protection Systems (PCCC): Allows quick shut-off in emergencies.
• Other Industrial Sectors: Oil & gas, mining, shipbuilding, and more.
