ASCO手动复位电磁阀/WSNF8327B102

优点：
1，流体阻力小、球阀是所有阀类中流体阻力小的一种，即使是缩径球阀，其流体阻力也相当小。
2，止推轴承减小阀杆摩擦力矩，可使阀杆长期操作平衡灵活。
3，阀座密封能好，采用聚四氟乙烯等材料制成的密封圈，结构易于密封，
而且球阀的阀封能力随着介质压力的增设而增大。
4，阀杆密封可靠，由于阀杆只作旋转运动而不做升降运动，
阀杆的填料密封不易破坏，且密封能力随着介质的压力增设而增大。
5，由于聚四氟乙烯等材料具有良好的自润滑，与球体的摩擦损失小，帮球阀的使用寿命长。
6，下装式阀杆和阀杆头部凸阶防止阀杆喷出，
如火灾造成阀杆密封破坏，凸阶与阀体间还可形成金属接触，确保阀杆密封。
