Core Definition and Function
A vacuum throttle valve is a key component in vacuum systems for precise control of gas flow and pressure. It achieves throttling, pressure stabilization, and flow distribution of gas in vacuum pipelines by adjusting the opening of the valve disc to change the flow cross-sectional area. Its core advantage lies in maintaining stable sealing performance and adjustment accuracy under high-vacuum or ultra-high-vacuum environments, widely applied in high-end fields such as semiconductor manufacturing, vacuum coating, scientific research, and aerospace.
Product Characteristics and Technical Advantages
-
High-precision Flow Control
Adopting precise valve core designs (such as needle valve or butterfly valve types), it enables a flow adjustment range of 0.1% to 100%, meeting the demand for (micro-precise control) of gas flow in vacuum systems (e.g., CVD deposition, ion beam etching processes).
-
Excellent Sealing Performance
The valve body is mostly made of 304/316 stainless steel, aluminum alloy, or fluororubber, paired with metal seals (such as oxygen-free copper gaskets) or fluororubber seals. The vacuum degree can reach below 10 Pa, effectively preventing external air infiltration or internal gas leakage.
-
Rapid Response and Long Service Life
Pneumatic or electric drive models feature a response time ≤ 0.5 seconds and a mechanical life exceeding 100,000 cycles, suitable for high-frequency operations in automated production lines.
Application Scenarios and Foreign Trade Value
In the semiconductor industry chain, vacuum throttle valves control the gas flow (e.g., SiH4, NH3) during silicon wafer deposition, directly affecting the uniformity of chip films. In the vacuum coating field, they regulate metal vapor flow to improve the coating precision of optical components. For foreign trade customers, our products offer:
-
International Certification Support
Compliant with ISO 9001 and CE certifications, adapting to industrial standards in markets such as the EU and North America.
-
Customized Services
Providing flange interfaces (CF, ISO, KF), connection sizes (1/4"~4"), and special specifications like explosion-proof and high-temperature types based on customer needs.
-
Supply Chain Advantages
Supporting fast delivery for small batches (7~15 days), offering tiered pricing for bulk orders, and providing installation manuals and 24-hour responsive after-sales technical support.
