Features
1. Ultra-low leakage precision sealing to stably maintain vacuum degree
Adopts vacuum-specific dense sealing structure with high-elasticity and aging-resistant sealing materials. The sealing pair features high fitting accuracy and ultra-low system leakage rate, effectively preventing external gas infiltration and vacuum degree attenuation under negative pressure, ensuring constant system pressure and meeting strict sealing requirements of precision vacuum equipment.
2. Specialized negative pressure design with strong deformation resistance
The valve body is structurally optimized for negative pressure conditions with high shell rigidity and reasonable pressure-bearing structure. It can stably withstand long-term negative pressure suction without disc deformation, valve position deviation or loose sealing, ensuring fault-free continuous vacuum operation.
3. Dead-corner-free flow channel to avoid gas retention
No internal connecting rods, bolts or gas-accumulating grooves inside the valve. The smooth and transparent flow channel ensures jamming-free operation and no residual gas dead corners, enabling rapid vacuum exhaust and avoiding vacuum purity reduction caused by gas retention, suitable for high-cleanliness and high-precision vacuum processes.
4. Multiple driving and specification options with high automation
Compatible with manual, electric and pneumatic driving modes for on-site manual operation, remote automatic control and proportional regulation, adapting to various vacuum automatic control systems. Full-coverage connection specifications and pressure grades suit both laboratory small vacuum pipelines and industrial large-scale negative pressure production lines.
5. Fast opening/closing response and high exhaust efficiency
The 90-degree rotary butterfly structure features short stroke and sensitive action, enabling rapid pipeline switching. It cooperates with vacuum units to complete efficient vacuuming, pressure holding and pressure relief processes, significantly improving the overall operating efficiency of vacuum systems.
6. Wide temperature range and strong working condition adaptability
Applicable to the temperature range of -29℃ to 300℃, resisting alternating cold and heat in vacuum processes. The sealing material is high-temperature resistant and aging-resistant, maintaining stable sealing performance in high and low temperature negative pressure environments and adapting to various complex vacuum working scenarios.
7. Bidirectional flow design with flexible installation
Adopts a bidirectional flow structure without medium flow direction restrictions, allowing arbitrary angle and orientation installation. It adapts to dense pipelines and narrow equipment spaces with convenient installation and commissioning and strong on-site adaptability.
8. Reliable and durable structure with extremely low maintenance cost
The compact and simplified structure has fewer built-in parts and low failure rate without complex wearable transmission structures. The fatigue-resistant and aging-resistant seals ensure stable long-term negative pressure operation. No complicated daily maintenance is required, greatly reducing the operation and maintenance cost of vacuum systems.
