本產品為雙聯交叉流動型安全控制閥，通過兩組并聯結構的閥芯，保證在相等的先導控制壓力作用下，兩組閥芯同步動作。當控制失靈或自身發生故障，造成一組閥芯開啟，另一組閥芯處在關閉的狀態時在監控氣信號壓差作用下，監控器發出故障章信號安全閥關閉并被鎖定不能再啟動故障排除后.啟動搖控氣動或手動復位.使監控器復位.安全閥可以恢復正常工作。?K23JSD-L15L-G/R is a crossflow double valve. It has two valve elements which parallel connection .When the pilot valves are simultaneously energized ,the two main elements are operated simultaneously. When control fail or go wrong,one of the valve elements open and another one closed ,the pressure difference will make the monitor lock the valve. Only after repair, the valve can be start by air pressure remote neumatic control or manual Control.
