Pneumatic Operated High Vacuum Ball Valve
The Pneumatic Operated High Vacuum Ball Valve is specifically designed for systems where the working pressure is below standard atmospheric pressure, creating a controlled vacuum environment. This straight-through, spherical-seal valve is ideal for isolating or connecting sections of a vacuum system.
Features & Vacuum Performance
- Vacuum Application Range: Suitable for vacuum levels ranging from 0.6*10 ^6 to 1.3*10^-4Pa
- Versatile Operation: The spherical sealing design allows the valve to be reliably used in both high vacuum and low pressure (non-vacuum) states.
- Zero Leakage Sealing: Features a tongue-and-groove fit seat design which prevents deformation and ensures zero leakage under vacuum conditions.
- Convenient Maintenance: Designed with a double-flat, precision-meshing structure to prevent corrosion and facilitate easy assembly and disassembly.
- Reliable and Durable: Conforms to the ISO5211 standard high platform design for easy actuator mounting and a long service life.
- Optimized Performance: Provides bidirectional sealing and bidirectional pressure resistance with a low operating torque and excellent flow characteristics (high flow rate).
- Installation Flexibility: Can be installed in any position to connect or shut off the flow of media in vacuum system pipelines.
