DHRF系列电动衬氟O型球阀是旋转切断型球阀它由ARSOTA阿斯塔智能型电动执行机构和衬氟塑球阀两部分组成。由于该阀内腔及球体均采用高压注塑工艺，衬有耐腐蚀、耐老化的氟塑料FEP(简称F46)或PTFE(简称F4)，故具有可靠的耐腐蚀性和密封性。能广泛适用于化工、石油、冶金、医药、电力等工业部门，实现对生产过程中酸、碱等强腐蚀介质的调节或切断。
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.特点Feature：
1.耐腐蚀：阀体内腔及球体均包衬2.5～3㎜厚的F46或F4，能耐酸、碱、耐强腐蚀。
2.采用软密封阀座，密封性能好。
3.体积小，重量轻，结构简单，安装维修方便。
4.流阻小，流通能力大。
5.如配用阀门定位器，可实现比例调节。
6.该阀可配各种型号的电动执行机构，配套成ZDRF－10/16C型电动衬氟塑O型球阀。
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.
