Industrial piping systems require reliable flow control solutions, and the DN100 PN16 butterfly valve stands as a critical component for medium-pressure applications. This quarter-turn valve design incorporates a disc mounted on a rotating shaft, enabling swift isolation in pipelines with 100mm nominal diameter (DN100) and 16-bar pressure rating (PN16). Manufacturers achieve precise sealing through resilient seat designs that maintain integrity up to 16 bar internal pressure, equivalent to 230 PSI. Standard compliance includes ISO 5752 flange dimensions and EN 593 leakage standards, ensuring compatibility with existing pipeline infrastructures.
Engineers evaluate valve performance through quantifiable metrics that impact system efficiency. For PN16 butterfly valves, pressure testing exceeds nominal ratings by 150% during hydrostatic tests, while flow coefficient (Cv) values range from 650-850 depending on disc configuration. Temperature tolerance spans -20°C to +120°C for standard EPDM seats, extendable to +180°C with specialized Viton seals. Critical dimensions conform to international standards, with face-to-face lengths of 43mm and flange bolt circle diameters of 185mm for DN100 valves. Flow regulation testing reveals:
Valve selection requires careful evaluation of manufacturer specifications for DN100 PN16 applications. Performance variations significantly impact lifecycle costs, maintenance frequency, and system reliability. The table below compares critical parameters across industry-leading suppliers:
| Feature | Manufacturer A | Manufacturer B | Manufacturer C |
|---|---|---|---|
| Body Material | Ductile Iron GG40 | Cast Iron GG25 | Carbon Steel A216 |
| Seat Material | EPDM (+110°C) | NBR (+80°C) | PTFE (+200°C) |
| Disc Type | Eccentric Design | Double Eccentric | Triple Eccentric |
| Flow Capacity | Cv 720 | Cv 685 | Cv 810 |
| Cycles Rating | 100,000+ | 50,000 | 200,000 |
| Certifications | ISO 9001, PED | ISO 9001 | API 609, TA-Luft |
Beyond standard DN100 PN16 butterfly valves, custom-engineered options address unique operational challenges across industries. For aggressive chemical processing, manufacturers apply specialized coatings like Halar or Xylan that withstand pH levels from 0-14. Fire-safe designs incorporate graphite seats compliant with API 607 standards. In potable water systems, WRAS-approved stainless steel components eliminate contamination risks. Specialized configurations include:
Water treatment facilities in Manchester recently deployed 280 DN100 PN16 butterfly valves with electro-polished stainless steel internals. This installation reduced particulate contamination by 92% while extending maintenance intervals from quarterly to biannual service cycles. In chemical processing plants along the Rhine Valley, specialized triple-offset valves with Alloy 20 discs demonstrated corrosion resistance against sulfuric acid concentrations up to 70%, extending service life from 18 months to over five years. Oil refinery projects in Texas documented 35% installation time reduction through standardized PN16 butterfly valve assemblies with lug-style connections.
Proper maintenance extends the operational lifespan of DN100 PN16 butterfly valves beyond typical 10-year benchmarks. Quarterly visual inspections should verify seal integrity and shaft alignment, while annual performance tests must include:
Predictive maintenance programs utilizing IoT sensors have demonstrated 20% reduction in unexpected failures and 45% decrease in maintenance costs by continuously monitoring parameters like friction torque and cycle count.
Optimizing flow control systems requires matching valve specifications to operational parameters. The DN100 PN16 butterfly valve represents the ideal solution for medium-pressure applications across diverse industries. These valves consistently demonstrate 98.5% shutoff reliability in water distribution networks and maintain precision flow control (±5%) when paired with modulating actuators. Their compact installation footprint saves up to 70% space compared to gate valves with equivalent ratings, while quarter-turn operation ensures rapid emergency response. With proper specification accounting for media compatibility and temperature parameters, these valves deliver consistent performance in critical infrastructure applications globally.

A: DN100 indicates a nominal diameter of 100mm, while PN16 denotes pressure rating of 16 bar. Together, they define valve size and maximum working pressure capacity in piping systems.
A: Yes, these are identical product references in varied word order. Both describe a wafer-style butterfly valve with 100mm bore size rated for 16 bar pressure.
A: Check manufacturer datasheets showing flange-to-flange length, disc diameter, and bolt circle dimensions. Standard ISO 5752 provides face-to-face measurements for PN16 DN100 butterfly valves.
A: Typically engineered for ISO 7005-1 or EN 1092-1 PN16 flanges. These international standards ensure compatibility with pipelines using 16mm stud bolts and RF facings.
A: Yes, when paired with appropriate elastomer linings (EPDM, Viton®, PTFE). Verify chemical compatibility charts since valve performance depends on seat material resistance to specific fluids.
