seal butterfly vacuum butterfly valve vacuum butterfly valves
A vacuum butterfly valve is used for isolating, regulating, or controlling the flow of media in vacuum systems. It provides a tight seal to maintain vacuum integrity, commonly used in semiconductor, pharmaceutical, and industrial processing equipment.
ISO-KF (quick-release) flanges are suitable for high-vacuum (HV) applications up to 10⁻⁷ mbar. CF (ConFlat) flanges with metal seals are required for ultra-high vacuum (UHV) applications requiring leak rates below 10⁻⁹ mbar·L/s. Your choice should match your system's pressure and outgassing requirements.
Our MOQ for standard OEM vacuum butterfly valves is 5–10 units per size for initial qualification. For custom OEM designs (special materials/actuators), the MOQ is typically 50–100 units. We are flexible for pilot projects and R&D teams.
Every valve undergoes a 6-step QC process: material certification, CNC machining inspection, dimensional check, 100% helium mass spectrometer leak testing, assembly verification, and final actuation test. We also provide a Certificate of Conformance (CoC) with each shipment.
Standard production lead time is 30 days. Sea freight (FOB Tianjin) to the US West Coast typically takes 18–22 days. Air freight (CIF) takes 5–7 days. We offer consolidated shipping to reduce freight costs. Contact us for a detailed freight quote based on your order volume.
Yes. Our engineering team provides free remote technical support and documentation. We also offer a 12-month warranty against manufacturing defects. For large OEM accounts, on-site installation supervision can be arranged.
We accept T/T (wire transfer), L/C (irrevocable), Western Union, and for qualified US/EU clients, net-30 terms may be available after credit evaluation.
