本产品为双联交叉流动型安全控制阀，通过两组并联结构的阀芯，保证在相等的先导控制压力作用下，两组阀芯同步动作。当控制失灵或自身发生故障，造成一组阀芯开启，另一组阀芯处在关闭的状态时在监控气信号压差作用下，监控器发出故障章信号安全阀关闭并被锁定不能再启动故障排除后.启动摇控气动或手动复位.使监控器复位.安全阀可以恢复正常工作。 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.
