Product Details
Swiss VAT high-pressure swing isolation valve 16.2 series
1. Product Overview
Model Series：VAT 16.2
Valve TypeHigh pressure Swing Gate Valve
Design features：
90 ° swing arm opening and closing mechanism, saving 50% space compared to traditional gate valves
Double sealing system (main seal+emergency seal)
Suitable for cross working conditions of high pressure difference (≤ 20 bar) and high vacuum (10 ⁻⁹ mbar)
2. Key performance parameters
| parameter | technical indicators |
|---|---|
| pressure range | Ultra high vacuum (10 ⁻⁹ mbar)~20 bar (absolute pressure) |
| temperature range | -30 ° C~+150 ° C (standard)/+250 ° C (high temperature version) |
| leak rate | <1 × 10 ⁻⁹ mbar · l/s (metal seal) |
| Valve body material | 316L stainless steel (optional Hastelloy C-276) |
| Sealing material | Full metal seal (gold/copper) or fluororubber (FKM) |
| Drive Type | Pneumatic (standard)/Electric (optional stepper motor) |
| response time | <1 second (DN100 caliber) |
| Flange Standard | ISO-KF/CF/DN，ANSI 150#~300# |
3. Core technological advantages
① Swing arm design
Adopting VAT's Soft Touch technology to reduce particle generation (<5 particles/cm ³ @ 0.3 μ m)
70% reduction in wear compared to traditional gate valves (lifespan>500000 cycles)
② Dual redundant sealing system
main sealMetal seal (standard operating conditions)
Emergency sealingQuick activatable elastomer seal (automatically triggered in case of sudden pressure fluctuations)
③ Intelligent diagnostic interface
Integrated valve position sensor (accuracy ± 0.1 °)
Support predictive maintenance (monitoring sealing status through vibration/temperature)
4. Industry application cases
| industry | Typical Applications | customized requirements |
|---|---|---|
| semiconductor | Etching machine chamber isolation | Aluminum oxide coating, resistant to Cl ₂ corrosion |
| energy | Fusion device vacuum isolation | Non magnetized design (titanium alloy components) |
| chemical industry | High pressure reactor feed control | Hastelloy valve body, acid and alkali resistant |
| scientific research | Synchrotron radiation beamline | Ultra high vacuum compatibility (baked to 250 ° C) |
5. Selection Guide
| Model Example | DN caliber | pressure rating | sealed type | Applicable scenarios |
|---|---|---|---|---|
| VAT 16.2-100-M | DN100 | 10 bar | metal seal | semiconductor equipment |
| VAT 16.2-150-H | DN150 | 20 bar | Hastelloy seal | Chemical high-pressure reaction |
| VAT 16.2-80-XHV | DN80 | Vacuum specific | Bimetallic seal | EUV lithography machine |
6. Installation and maintenance
Installation specifications：
A torque wrench is required (see table below for flange bolt torque)
Perform 3 pressure cycle tests (0-20 bar) before use
| Flange Standard | Bolt torque (Nm) | Tightening sequence |
|---|---|---|
| DN100 ISO-KF | 12~15 | Cross over method |
| 4' ANSI 150# | 60~75 | Star shaped progressive approach |
