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(zhí)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(yī)藥、電力等工業(yè)部門，實現(xiàn)對生產過程中酸、堿等強腐蝕介質的調節(jié)或切斷。
DHRF O-series electric fluorine spin cut-off valve is a valve which consists of ARSOTA Astana intelligent 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.
一.特點Feature：
1.耐腐蝕：閥體內腔及球體均包襯2.5～3㎜厚的F46或F4，能耐酸、堿、耐強腐蝕。
2.采用軟密封閥座，密封性能好。
3.體積小，重量輕，結構簡單，安裝維修方便。
4.流阻小，流通能力大。
5.如配用閥門定位器，可實現(xiàn)比例調節(jié)。
6.該閥可配各種型號的電動執(zhí)行機構，配套成ZDRF－10/16C型電動襯氟塑O型球閥。
1 Corrosion resistance: the body cavity and the sphere are lining package ~ 3 mm thick, 2.5 F46 or F4, to acid, alkali, strong corrosion resistance.
2 soft sealed valve seat, sealing performance.
3 small size, light weight, simple structure, convenient installation and maintenance.
4 small flow resistance, flow capacity.
5 equipped with a valve positioner, such as, the proportion of adjustment can be achieved.
6 The valve can be equipped with various types of electric actuators, electric facilities into ZDRF-10/16C fluorine plastic O-ball.
