What is butterfly valve ？

We provide variety of butterfly valves.

A butterfly valve is a compact, cost-effective flow control device used to regulate or isolate fluid in pipelines. Its disc rotates like a butterfly’s wing, enabling quick operation and minimal pressure loss. Perfect for industrial applications, these valves are essential for water treatment, HVAC systems, and chemical processing.

At DKV Valve, we combine Chinese manufacturing efficiency with global quality standards. Whether you’re a procurement manager, distributor, or engineering contractor, our valves ensure seamless operations.

Types of Butterfly Valves

Butterfly valves are indispensable for fluid control in pipelines, but their performance hinges on selecting the right type. Among the most common designs are wafer butterfly valves, lug butterfly valves, and flanged butterfly valves—each tailored to specific connection styles, pressure demands, and operational environments.

  • Wafer Butterfly Valves
  • Lug Butterfly Valves
  • Flanged Butterfly Valves

Wafer Butterfly Valve

Lug Type Butterfly Valve

Flanged Butterfly Valves

Wafer Butterfly Valves

Design & Functionality
• Connection Style: Sandwiched between two pipe flanges using bolts.
• Pressure Rating: Typically PN10-PN16 (150 psi to 232 psi).
• Applications: Ideal for low-pressure systems like water supply, HVAC, and light-duty industrial processes.
Advantages
• Compact design saves space and reduces weight.
• Cost-effective for bulk installations.

Lug Butterfly Valves

Design & Functionality
• Connection Style: Threaded inserts (lugs) allow valve installation between flanges without nuts.
• Pressure Rating: PN10-PN25 (150 psi to 362 psi).
• Applications: Suitable for moderate-pressure systems, including fire protection and chemical processing.
Advantages
• Allows one side of the pipeline to be disconnected without affecting the other.
• Durable construction for medium-duty applications.

Material of butterfly valve

Butterfly valves control fluid flow in pipelines, and material choice directly impacts their performance.

At DKV Valve, we engineer stainless steel butterfly valves and cast iron butterfly valves to meet diverse industrial demands. Below, we break down their technical specifications, applications, and real success stories.

1

Stainless Steel Butterfly Valves

Material Properties & Technical Specifications

  • Temperature Range: -20°C to 200°C (-4°F to 392°F)
  • Pressure Rating: PN10-PN40 (150 psi to 300 psi)
  • Compatible Media: Water, steam, acids, alkalis, oils, and corrosive chemicals.
  • Key Advantage: Superior corrosion resistance (ideal for SS304/SS316 alloys) and hygienic design for sensitive industries.

Case Example

  • Chemical Plant in Indonesia
  • A chemical plant required valves for sulfuric acid transfer (pH <2). DKV Valve’s stainless steel butterfly valves (SS316) were selected for their:
  • Acid resistance at 80°C (176°F).
  • Zero leakage under 10-bar pressure.
  • Result: 5-year service life with 50% lower replacement costs.
2

Cast Iron Butterfly Valves

Material Properties & Technical Specifications

  • Temperature Range: -10°C to 120°C (14°F to 248°F)
  • Pressure Rating: PN6-PN16 (90 psi to 232 psi)
  • Compatible Media: Water, air, non-corrosive oils, and neutral gases.
  • Key Advantage: Cost-effective for bulk orders in low-to-medium pressure systems.

Case Example

  • Water Supply Project in Vietnam
  • A municipal water network needed 800+ valves for a 50km pipeline. DKV Valve’s cast iron butterfly valves provided:
  • Reliable performance at 8-bar pressure.
  • Full compatibility with potable water (EN-GJL-250 certified).
  • Result: 20% faster project completion with 35% budget savings.

DKV VALVE

Why Choose DKV Valve?
