本廠生產(chǎn)的雙偏心半球球閥經(jīng)過在石化、冶金、電力、輕工等行業(yè)的實踐,證明了我廠生產(chǎn)的雙偏心半球球閥能滿足用戶對壓力、溫度、介質(zhì)及口徑參數(shù)不同的要求。尤其對一些惡劣工況條件,使用本廠產(chǎn)品后大大延長了系統(tǒng)上更換檢修閥門的時間間隔,深受用戶歡迎。
The dual-eccentric semi-ball ball valves made in this factory have been verified,via the practice in petrochemical,metallu rgic,electric power,light etc industries,to be capable of satisfying the different requirements of the users on temperature,pressure,medium and aperture parameter and,especially for some harsh work conditions,greatly extending the time interval in valve replacement and repair,greatly favored by the users
