    TFA48Y高溫高壓安全閥

    Description:
    系列 Series
    先導式安全泄壓閥是一種新穎結構的安全閥。主要用于石油天然氣、化工、電力、冶金和城市燃氣等領域,是受壓設備、容器或管路上的最佳超壓保護裝置。其主要優點是變彈簧直接作用為導閥間接作用,提高了動作的靈敏度,而且主閥采用套筒活塞式,雙重密封閥座結構,動作精度高、重復性好、回座快、不泄漏、能帶高背壓排放、工作壽命長、工作穩定可靠,它還可在線調校,反復啟跳排放后,仍然能自動回座,關閉嚴密,操作維護方便。
    Pilot operated safety valve,newly-structured, is mainly applied to such trades as petroleum & nat-ural gas, chemistry, electric, meta-llurgy & burning gas. It is the best super-pressure protecting equipment on press equipment, container, or pipeline, It is mainly characterized by shifting direct function of spring to indirect function of guide valve. What's more, main valve, applying for sleeve piston & double sealed seat, is characterized by high pre-cision of action, good recycling function, fast turning back to seat, ability to high-pressure leaking, long working time & security, toge-ther with read-justment on line,
    aucomatic turning back to seat after leaking again and again, tight closure, operating and main-taining conve-nience.
