衬氟球阀是用带圆形通孔的球体作启闭件，球体随阀杆绕阀体中心线旋转以实现阀门开启和关闭。采用特殊的模压工艺，使密封面致密良好，加之V型PTFE填料组合使阀门达到零泄漏;球体与阀杆铸为一体，杜绝了由于压力变化引起阀杆冲出承压件内的可能性，根本保证使用中的安全性;采用全塑料衬里工艺，耐介质的强腐蚀。
驱动：衬氟球阀按驱动方式有手动衬氟球阀、蜗轮转动衬氟球阀、气动衬氟球阀、电动衬氟球阀等。
特点：
1.采用氟塑料衬里层的球阀，具有极高的化学稳定性，适用于任何强腐蚀性化学介质;
2.采用全通浮动球阀结构，在整个压力范围内进行元泄漏关闭，便便于管路系统在通球扫线和管路维护。
用途：衬氟球阀为控制各种强腐蚀性介质的启闭而进行的专业设计，广泛使用于石油，化工，染化，农药，制酸制碱等行业，是目前防腐阀门最理想的选择.
