Understanding the Butterfly Valve DN100 PN16

The butterfly valve DN100 PN16 represents a critical component in industrial fluid control systems. Designed for nominal diameter (DN) 100 mm and pressure rating (PN) 16 bar, this valve balances compact design with high-performance sealing. Its lug-type or wafer-style configuration ensures compatibility with pipelines in water treatment plants, chemical processing, and HVAC systems. Key metrics include:

Leakage rate: ≤0.1% of rated flow capacity
Operational lifespan: 15,000+ cycles
Temperature range: -20°C to +150°C

Technical Superiority in Design

Advanced butterfly valves utilize dual-seal technology with EPDM/NBR seats and 316L stainless steel discs. The PN16 pressure rating ensures reliable performance in systems requiring 16-bar working pressure with 24-bar surge tolerance. Compared to traditional gate valves, DN100 models reduce weight by 40% while maintaining equivalent flow capacity.

Industry Application Scenarios

A municipal water project achieved 92% pump efficiency improvement after replacing 78 gate valves with DN100 PN16 butterfly valves. In offshore platforms, modified versions withstand 3.5% salinity corrosion at 25m depth.

Final Considerations for Butterfly Valve DN100 PN16 Selection

When specifying pn16 butterfly valve dimensions, verify flange face-to-face measurements (108mm for wafer-style) and shaft tolerance (±0.05mm). Leading suppliers provide 24-month lead times for bulk orders exceeding 500 units, with FEA-validated designs ensuring 98.6% failure-free operation.

FAQS on butterfly valve dn100 pn16

What are the dimensions of a PN16 butterfly valve in DN100?

Q: What are the dimensions of a PN16 butterfly valve in DN100?
A: A DN100 PN16 butterfly valve typically has a flange diameter of 220mm, a bolt circle of 180mm, and uses 8xM20 bolts. Exact dimensions may vary slightly by manufacturer.

What is a DN100 PN16 butterfly valve used for?

Q: What is a DN100 PN16 butterfly valve used for?
A: It regulates or isolates fluid flow in pipelines, suitable for water, air, or non-corrosive media in systems requiring 16-bar pressure resistance and 100mm nominal diameter.

Are there specific installation requirements for a DN100 PN16 butterfly valve?

Q: Are there specific installation requirements for a DN100 PN16 butterfly valve?
A: Install between flat-faced flanges (EN 1092-1 standard), ensuring proper gasket alignment. Avoid over-tightening bolts to prevent disc interference.

What distinguishes a PN16 butterfly valve from lower-pressure valves?

Q: What distinguishes a PN16 butterfly valve from lower-pressure valves?
A: PN16 valves have thicker bodies/seats and reinforced components to withstand 16-bar operating pressure. Flange dimensions also differ from lower classes like PN10.

Does the DN100 PN16 butterfly valve come in stainless steel?

Q: Does the DN100 PN16 butterfly valve come in stainless steel?
A: Yes, many models offer 316/304 stainless steel construction for corrosive environments. Check manufacturer specs for material certifications and chemical compatibility.
