聯(lián)系我們時，請說明來自網(wǎng)絡(luò)，有優(yōu)惠價哦！ 本產(chǎn)品為雙聯(lián)交叉流動型安全控制閥，通過兩組并聯(lián)結(jié)構(gòu)的閥芯，保證在相等的先導(dǎo)控制壓力作用下，兩組閥芯同步動作。當(dāng)控制失靈或自身發(fā)生故障，造成一組閥芯開啟，另一組閥芯處在關(guān)閉的狀態(tài)時，在監(jiān)控氣信號壓差作用下，監(jiān)控器發(fā)出故障信號，安全閥關(guān)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(fù)位，使監(jiān)控器復(fù)位，安全閥可以恢復(fù)正常工作。 K23JSD-L15L-G/R is a crossflow double relief 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 pneumatic control or manual control .
