(截止止回節流)進口多功能定流量控制閥 性能特點∶ Performance characteristics

有一個開度指示器顯示閥門的開合程度 There is an opening indicator to show the opening and closing degree of the valve

閥瓣密封面是由直接硫化在球墨鑄鐵閥瓣上的EPDM橡膠構成，因而可以吸收關閉閥瓣時所產生的沖擊，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

一閥多用,實現截止、節流、止回閥三臺閥門功能 One valve is multi-purpose, realizing the functions of three valves, namely, stop valve, throttle valve and check valve
