Q646F pneumatic four-way valve
Product Name:
Q646F pneumatic four-way valve
Description:

气动四通球阀 Q646F

用途及特点
1、流体阻力小:球体和阀体的连接管道截面相等,且球体通道采用圆弧连接,介质通过球体时,流体阻力小。
2、密封性能女子: 阀座采用具有一定弹性变形和高强度的PTFE材料,达到良好密封性能保证了阀门的稳定性。
3、使用寿命长: 阀门的阀芯和光颈材料采用奥氏不锈钢,阀座材料选用PTFE, 能达到良好的抗腐蚀性作用,延长了阀门使用寿命。

执行标准 
I 设计和制造:GB/T12237989; APl608。
2.检验和试验:GB/T13927992; APl 598。
3 法兰连接:JB/T79]一2994; ASME/ANSI B165。
