气动球阀与其它种类阀门相比，具有角行程输出扭矩，开启迅速、平稳可靠，适用广泛，以及以下一些优点：1、止推轴承减小阀杆摩擦力矩，可使阀杆长期操作平稳灵活。2、防静电功能：在球体、阀杆、阀体之间设置弹簧，能将开关过程中产生的静电导出。3、由于聚四氟乙烯等材料具有良好的自润滑性，与球体的摩擦损失小，故气动球阀的使用寿命长。4、流体阻力小：气动球阀是所有阀门分类中流体阻力***小的一种，即使是缩径气动球阀，其流体阻力也相当小。5、阀杆密封可靠：由于阀杆只作转动运动而不做升降运动，阀杆的填料密封不易***，且密封能力随着介质压力的***而增大。台湾登胜JANUS电磁阀D4-03-2B2-D2D4-03-2B3-D2D4-03-2B8-D2D4-03-2B2A-D2D4-03-2B3A-D2D4-03-2B4A-D2D4-03-2B40A-D2D4-03-2B5A-D2D4-03-2B60A-D2D4-03-2B7A-D2D4-03-2B8A-D2D4-03-2B9A-D2D4-03-2B10A-D2D4-03-2B11A-D2D4-03-2B12A-D2D4-03-2B2B-D2D4-03-2B3B-D2D4-03-2B4B-D2D4-03-2B40B-D2D4-03-2B5B-D2D4-03-2B60B-D2D4-03-2B7B-D2D4-03-2B8B-D2D4-03-2B9B-D2D4-03-2B10B-D2D4-03-2B11B-D2D4-03-2B12B-D2台湾登胜JANUS电磁阀D4-03-3C2-D2D4-03-3C3-D2D4-03-3***-D2D4-03-3***0-D2D4-03-3C5-D2D4-03-3C60-D2D4-03-3C7-D2D4-03-3C8-D2D4-03-3C9-D2D4-03-3C11-D2D4-03-3C12-D2D4-03-2D2-D2D4-03-2D3-D2D4-03-2D7-D2D4-03-2D8-D2D4-03-2D2A-D2D4-03-2D3A-D2D4-03-2D40A-D2D4-03-2D5A-D2D4-03-2D7A-D2D4-03-2D9A-D2D4-03-2D10A-D2D4-03-2D11A-D2D4-03-2D12A-D2台湾登胜JANUS电磁阀D5-02-2B2-A2D5-02-2B3-A2D5-02-2B8-A2D5-02-2B2A-A2D5-02-2B3A-A2D5-02-2B4A-A2D5-02-2B40A-A2D5-02-2B5A-A2D5-02-2B60A-A2D5-02-2B7A-A2D5-02-2B8A-A2D5-02-2B9A-A2D5-02-2B10A-A2D5-02-2B11A-A2D5-02-2B12A-A2D5-02-2B2B-A2D5-02-2B3B-A2D5-02-2B4B-A2D5-02-2B40B-A2D5-02-2B5B-A2D5-02-2B60B-A2D5-02-2B7B-A2D5-02-2B8B-A2D5-02-2B9B-A2D5-02-2B10B-A2D5-02-2B11B-A2D5-02-2B12B-A2)
