Eliminate contamination risks and reduce procurement costs by up to 40% with Thriveon’s precision-engineered high vacuum butterfly valve. Designed for semiconductor, pharmaceutical, and analytical instrumentation systems requiring leak rates < 1x10⁻⁹ mbar·l/s.
In high-vacuum processes, a standard valve is a weak link. Engineering teams and procurement managers often face these critical pain points:
Standard butterfly valves outgas or fail to seal consistently, leading to vacuum system leaks, batch contamination, and costly downtime in UHV chambers.
Legacy vacuum component suppliers charge 40-60% margins. Budget constraints force buyers to choose between quality and cost—until now.
Customized vacuum valves from traditional manufacturers require 8-12 weeks. Project timelines slip, and emergency orders incur heavy surcharges.
Need a specific flange (ISO-KF, CF, ISO-MF) or actuator type (pneumatic, manual)? Many suppliers lack the engineering bandwidth to adapt.
At Ningjin Thriveon Valve Co., Ltd., we designed our high vacuum butterfly valve series specifically for demanding moderate to high vacuum applications (down to 1x10⁻⁷ mbar). Our valves combine robust stainless steel construction (SS304 / SS316) with advanced sealing technologies to provide reliable isolation with minimal outgassing. Whether you need a standard configuration or a fully custom OEM design, our engineering team delivers.
Located in Hebei, China, our facility spans 15,000 sqm with CNC machining centers, automated welding, and clean-room assembly. Every valve undergoes 100% helium leak testing and functional cycling.
Our VH Series achieves an internal and external leak rate of < 1x10⁻⁹ mbar·l/s, suitable for UHV prep chambers, load locks, and sputtering systems.
Custom flange combinations, actuator mounting (ISO 5211), special seal materials (Viton, EPDM, Kalrez), and position feedback sensors. Your specs, our execution.
Standard valves ship in 15-25 days. Custom orders in 4-6 weeks. By manufacturing in-house, we offer prices 35-50% below EU/US distributors.

A high vacuum butterfly valve is designed to seal effectively in vacuum systems down to 1x10⁻⁷ mbar or lower. Unlike standard valves, it features lower outgassing materials (Viton/EPDM seals, SS316 bodies), a helium-tight leak rate, and typically uses ISO-KF, ISO-MF, or CF flanges for vacuum integrity.
Our VH Series valves offer an internal and external leak rate of < 1x10⁻⁹ mbar·l/s, tested via helium mass spectrometry. This makes them suitable for ultra-high vacuum (UHV) backing and roughing applications.
Yes. We offer ISO-KF, ISO-MF, CF, ANSI, and JIS flanges. Actuation options include manual handle, pneumatic (single/double acting), and electric (24V/110V/220V). We can also integrate solenoid valves and position feedback (mechanical or proximity sensors) per your request.
Standard valves are manufactured and shipped within 15-25 working days. Customized OEM orders typically require 4-6 weeks depending on complexity. We offer expedited production for urgent requirements.
Every valve undergoes 100% inspection including dimensional checks, hydrostatic pressure testing (1.5x rated pressure), and helium leak detection. Our manufacturing processes are ISO 9001:2015 certified, with full material traceability provided upon request.
Yes. For qualified engineering projects, we offer free standard samples (customer covers shipping). This allows your team to validate fit, form, and function before committing to a full volume order.
We accept T/T bank transfer, L/C (Letter of Credit), and Western Union. For long-term partnerships, we offer flexible payment terms based on order history and project scale.

“We transitioned to Thriveon for our load lock valves. The quality is excellent, and the lead time consistency (20 days vs 45 days from our previous supplier) keeps our line running. Highly recommend their high vacuum butterfly valve.”
Operations Director, Analytical Instruments (Italy)
“Thriveon’s engineering team customized the actuator mounting pattern for our legacy system without any additional tooling charges. The valve has been cycling reliably for over 250,000 operations. True partnership.”
Lead Scientist, National Research Lab (USA)
“We needed a non-standard ISO-MF configuration for our UHV chamber. Thriveon delivered a solution with a leak rate of 8x10⁻¹⁰ mbar·l/s. Unbeatable technical capability for the price point.”
