PVC Chemcock和刻度针形阀
PVC Chemcock and Calibrated Needle Valves

22oC温度下压力为150 psi，非冲击性水，全流道，全端口
150 psi at 73°F water –non-shock–full port
　　Chemtrol Chemcock阀门特别适用于实验室，监控系统，取样，以及各种作为原始设备的其他应用。它的(4.8)计算出来的流体流量系数(Cv)是以铺设长度为基础，等同于DN6 Schedule 80管道。
　　The Chemtrol Chemcock Valve is ideal for laboratories, monitoring systems, sampling, and a variety of other applications as original equipment. Its (4.8) calculated fluid flow coefficient (Cv) is based on the laying length being equivalent to 1/4" Schedule 80 pipe.
