Understanding DN150 Butterfly Valve Dimensions and Specifications

The DN150 butterfly valve represents a critical component in industrial piping systems, with nominal dimensions of 150mm (6 inches). Standard measurements include:

• Face-to-face length: 108mm (ASME B16.10 compliant)
• Flange diameter: 225mm
• Disc thickness: 18-22mm depending on pressure class

Pressure-temperature ratings typically range from PN16 to PN25, accommodating operating conditions up to 120°C (248°F) for standard rubber-seated models.

FAQS on dn150 butterfly valve dimensions

Q: What are the standard dimensions of a DN150 butterfly valve?

A: A DN150 butterfly valve typically has a nominal diameter of 150 mm (6 inches) with a flange spacing of 108 mm. Its face-to-face length adheres to ISO 5752 standards, usually 108 mm. Bolt hole patterns follow 8x22 mm for standard flange connections.

Q: Is a DN150 butterfly valve suitable for high-pressure applications?

A: DN150 butterfly valves are generally designed for low to medium pressure systems (up to 16 bar). For high-pressure use, reinforced materials like stainless steel or specialized seat designs (e.g., metal-seated) are recommended.

Q: What distinguishes a manual wafer butterfly valve DN150 from other types?

A: A manual wafer-style DN150 valve lacks flange bolts, relying on pipeline flange compression for installation. It features a compact design, lever or gear operator, and is 40-60% lighter than lug-type valves, ideal for space-constrained systems.

Q: How many bolt holes does a DN150 butterfly valve flange have?

A: Standard DN150 (PN16) flanges have 8 bolt holes arranged in a 185 mm bolt circle diameter. The holes are sized for M20 bolts per ISO 7005-2 specifications, ensuring compatibility with most piping systems.

Q: Can a wafer-style DN150 butterfly valve handle bidirectional flow?

A: Most wafer-type DN150 valves are bidirectional but perform optimally when installed with the disc rotating parallel to flow direction. Check manufacturer specifications as some designs may have flow orientation requirements for sealing efficiency.
