EN 593 is the European standard for industrial butterfly valves, covering design, face-to-face dimensions, pressure/temperature ratings, and testing. It ensures interchangeability and reliable performance across manufacturers. For international projects, specifying EN 593 guarantees compliance with EU directives and simplifies inspection.
Absolutely. We supply bare shafts, lever-operated, gearbox, and fully automated packages. Our ISO 5211 top flanges allow direct mounting of actuators from brands like Auma, Rotork, and Emerson. We also provide complete actuator sizing and testing.
For stock sizes (DN50–DN600) MOQ is 5 units; lead time 7–10 days. For engineered-to-order sizes (DN700–DN1200) MOQ is 2 units; lead time 4–6 weeks. We offer a free sample for qualification before bulk order.
We follow API 598 and EN 12266-1 testing procedures. Every valve is shell-tested and seat-tested with a full pressure chart. We provide material certificates (EN 10204 3.1), NDE reports, and CE declaration of conformity. For US projects, we also offer NACE MR0175 and CRN registration support.
Yes. We can apply your logo, color scheme, and custom packaging (IPPC-compliant wooden crates, plywood boxes, or export pallets). Our OEM team has delivered private-label valves for 15+ global brands.

"We've standardized on Thriveon's EN 593 valves across three plants. Consistent quality, fast delivery, and their engineering team helped us adapt the face-to-face for a retrofit. Highly recommend."
"The duplex discs with PTFE seat passed our fugitive emission test with zero leakage. The CE documentation was thorough — saved us weeks of compliance work."
"We needed 150 DN200 valves for a water transmission project. Thriveon delivered in 5 weeks — faster than any European supplier could quote. Quality was excellent."
"We switched from a German brand to Thriveon and saved 32% on total landed cost. The OEM gearbox integration was seamless. Our maintenance team loves the easy adjustment."
"Mining applications are brutal. Thriveon's heavy-duty EN 593 valves with hardened disc have outlasted our previous supplier's product by 2:1. Great after-sales support too."
