600S 系列的阀体、阀板均用钢板焊接加工而成，是一种重量轻、结构简单的蝶阀。适用于低压状态的空气或其它气体的流量、压力控制，此外也适用于高温状态的气体。

The valve body and the disc of the 600S Series Butterfly Valves are made of machined steel plates. This allows light and simple construction. Typical applications are flow/pressure controls of low-pressure air and gas. Hight temperature fluid at low pressure levels can also be accommodated inexpensively and easily.
