From the US to Saudi Arabia, South Africa to Italy — our customers rely on Thriveon for consistent quality, accurate dimensions, and on-time delivery.
"We ordered 124 DN200 double flanged butterfly valves for a refinery expansion. Every single valve matched the dimension chart perfectly — zero rework. Thriveon's quality control is world-class."
— Michael T., Procurement Manager, Texas Refining Co.
"The double flanged butterfly valve dimensions PDF they provided saved our engineering team 3 weeks of verification work. valves arrived 5 days early. We've already placed 3 repeat orders."
— Ahmed R., Sr. Project Engineer, Saudi Water Authority
"I've been importing valves from China for 8 years. Thriveon is the only supplier that delivers on dimensional accuracy consistently. Their lug type butterfly valve dimensions are spot-on."
— Giovanni P., Owner, Milan Valve Distributors
"We needed a custom face-to-face dimension for a retrofit project. Thriveon's engineering team designed it in 36 hours and shipped within 12 days. Unbelievable service."
— James K., Operations Director, Ontario Mining Corp.
"The PN16 double flanged butterfly valves we ordered for a desalination plant passed third-party inspection on the first test. Thriveon's quality and pricing are unmatched."
— Khalid A., Supply Chain Head, Gulf Desalination Co.Answer: For ANSI 150, the face-to-face dimensions typically range from 43 mm (DN50) to 127 mm (DN500). Flange outer diameters and bolt-hole patterns follow ASME B16.5. We provide a full double flanged butterfly valve dimensions chart covering all standard sizes — request your free copy.
Answer: Unlike wafer type butterfly valve dimensions (designed for sandwich mounting between flanges) or lug type butterfly valve dimensions (threaded lugs for dead-end service), double flanged valves have full flange faces on both ends, making them ideal for high-pressure, high-cycle isolation where bolt-load retention is critical. Our catalog includes all three styles.
Answer: Yes — we offer a free double flanged butterfly valve dimensions PDF that includes 2D drawings, flange drilling templates, weight data, and actuator mounting details. Request your copy here →
Answer: Custom face-to-face lengths, special flange drilling (e.g., PN25/PN40, ANSI 300), or non-standard disc materials typically require 15–25 working days for production, plus shipping. For urgent needs, we can rush samples in 7–10 days via air freight.
Answer: Absolutely. We provide free samples (you pay shipping) for qualified buyers. You can test fitment, measure all double flanged butterfly valve dimensions against your piping, and validate quality before committing to a large volume order.
Answer: We accept T/T (wire transfer), L/C (irrevocable letter of credit), and for long-term partners, D/P or 30% deposit + 70% balance against B/L. All transactions are secured with clear invoicing and Incoterms 2024.
Answer: Each valve undergoes 100 % inspection using coordinate measuring machines (CMM) and go/no‑go gauges. Face-to-face, flange OD, bolt-hole diameter, and disc concentricity are checked. Our ISO 9001:2015 quality manual requires full traceability from casting to final packaging.
Answer: In the unlikely event of a dimensional discrepancy, we offer immediate replacement or full refund (including freight). Our after-sales team responds within 4 hours, and we maintain a $2M inventory buffer to resolve issues fast.
