(截止止回节流)进口多功能定流量控制阀 性能特点∶ Performance characteristics

有一个开度指示器显示阀门的开合程度 There is an opening indicator to show the opening and closing degree of the valve

阀瓣密封面是由直接硫化在球墨铸铁阀瓣上的EPDM橡胶构成，因而可以吸收关闭阀瓣时所产生的冲击，并且完全密封retz  The sealing surface of the valve disc is composed of EPDM rubber directly vulcanized on the ductile iron valve disc, so it can absorb the impact generated when the valve disc is closed and completely seal

一阀多用,实现截止、节流、止回阀三台阀门功能 One valve is multi-purpose, realizing the functions of three valves, namely, stop valve, throttle valve and check valve
