620S 系列的閥體、閥板均用鋼板焊接,是一種重量輕、結(jié)構(gòu)合理的三偏心蝶閥。適用于低壓狀態(tài)空氣及其他氣體的流量、壓力控制,此外也適用于高溫狀態(tài)的氣體。
The valve body and disc of the 620S series Butterfly valves are made of machined steel plates. This allows light and proper construction. Typical application are flow/pressure controls of low-pressure air and gas. Hight temperature fluid at low pressure levels can also be accommodated inexpensively and easily.
