角式衬氟截止阀、具有结构紧凑、启闭灵活、耐腐蚀性能强，行程短(一般为公称通经1/4)等优点。被广泛应用在石油、化工等管路系统中做截断介质用，但塑料衬里的截止阀严禁用做流量调节，以免节流口处产生的高速介质流冲蚀***密封面。阀瓣与阀杆设计为一体结构，用以防止由于管路压力波动造成内件冲出阀体的可能性，结构紧凑，使用安全。设计规范遵循GB/T12233，GB/T12235，ANSIB16.34标准驱动方式手动、蜗轮转动、气动(常开或常闭)、电动主要零部件材料表序号零件名称灰铸铁铸钢不锈耐酸铸钢超低碳不锈耐酸铸钢ZCPRPLRL1阀体/阀盖HT250WCBCF8CF8MCF3CF3M2球体/阀杆252Cr131Cr18Ni91Cr18Ni12Mo2Ti00Cr18Ni1000Cr17Ni14Mo23衬里/阀座PCTEF(F3),FEP(F46),PFA(可溶F4),PP,PO4填料压盖WCBCF8CF8MCF3CF3M5填料PTFE(F4)PTFE(F4)PTFE(F4)6活节螺栓351Cr17Ni21Cr17Ni27阀杆螺母ZCuAl10Fe3ZCuAl10Fe3ZCuAl10Fe38紧固螺栓351Cr17Ni21Cr18Ni9Ti9螺母450Cr18Ni90Cr18Ni910手柄WCBWCBWCB主要外形和连接尺寸公称通经LDD1D2fbZ-φdDN(mm)NPS(inch)PN1.0MPa151/2909565452144-φ14203/49510575552164-φ1425110011585652164-φ143211/4105135100782184-φ184011/2115145110853184-φ185021251601251003204-φ186521/21451801451203204-φ188031551951601353224-φ1810041752151801553228-φ1812552002452101853248-φ1815062252802402103248-φ2320082753352952653268-φ232501032539035032032812-φ233001237544040036842812-φ23PN1.6MPa151/2909565452144-φ14203/49510575552164-φ1425110011585652164-φ143211/4105135100782184-φ184011/2115145110853184-φ185021251601251003204-φ186521/21451801451203204-φ188031551951601353228-φ1810041752151801553248-φ1812552002452101853268-φ1815062252802402103288-φ2320082753352952653308-φ23PN2.5MPa151/2909565452164-φ14203/49510575552164-φ1425110011585652164-φ143211/4105135100782184-φ184011/2115145110853184-φ185021251601251003204-φ18)
