Chemtrol刻度针形阀特别适用于仪器设备和实验室工作需要的精确调节流体流量的场合。通过观察旋钮手柄和阀体上模铸的数字,可以精确调节流经DN6阀门的流量。
The Chemtrol Calibrated Needle Valve is
ideally suited to the fine regulation of liquid flow required in
instrumentation and laboratory work. The flow through the 1/4"
valve can be accurately adjusted by observing the knob handle exposing
numerals molded on the valve body. |
