降低排放 - 确保安全运行
You are here:
经过先进技术精益加工的PROTEGO®呼吸阀能保证在罐压低于呼吸阀设定压力时具有极佳的密封性。PROTEGO®的工厂生产标准PS-001要求对呼吸阀在泄放压力的90%时进行泄漏量测试，远远严苛于现行的国际标准如EPA、API2000和ISO28300.
PROTEGO®呼吸阀密封性能极佳，在储罐操作压力时能保证零泄漏。
PROTEGO®呼吸阀采用10%超压技术，灵敏度极高，在压力超过设定压力10%时即可达到完全开启且达到额定排放量，使储罐压力保持在最大允许压力范围内.PROTEGO® 10%超压技术能有效的降低排放和保证储罐安全运行。
图表显示根据VDI 3479计算出的采用10%、40%和100%三种超压值呼吸阀的罐区减排量对比。
PROTEGO®10%超压技术节能减排。
我们的产品值得信任
"PROTEGO® 呼吸阀密封性能极佳，其泄漏量远低于我们当地的环境保护法要求。我们非常满意PROTEGO® 的产品."
