DHRF系列電動襯氟O型球閥是旋轉切斷型球閥它由ARSOTA阿斯塔智能型電動執行機構和襯氟塑球閥兩部分組成。由于該閥內腔及球體均采用高壓注塑工藝，襯有耐腐蝕、耐老化的氟塑料FEP（簡稱F46）或PTFE（簡稱F4），故具有可靠的耐腐蝕性和密封性。能廣泛適用于化工、石油、冶金、醫藥、電力等工業部門，實現對生產過程中酸、堿等強腐蝕介質的調節或切斷。

DHRF O-series electric fluorine spin cut-off valve is a valve which consists of ARSOTA Astana inligent electric valve actuators and fluorine plastic composed of two parts. As the valve cavity and the sphere are using high-pressure injection molding process, lined with corrosion-resistant, anti-aging fluorine plastic FEP （referred to as F46） or PTFE （referred to as F4）, it has the corrosion resistance and reliable sealing. Can be widely used in chemical, petroleum, metallurgy, medicine, electricity and other industrial sectors, to achieve the production process, acid, alkali and other strong corrosive media regulation, or cut off.
