EATON安全阀RV11-12系列介绍
操作
当进口压力超过阀门设定值时，先导部分打开，使小流量通过主阀芯的节流孔。随后的降压使阀芯移动到一个轻弹簧上，打开套筒上的径向孔环，允许泄流入罐。
特点
高精度的先导操作设计。硬化的工作部件被赋予长期，可靠，无故障的使用寿命。
Operation
When the inlet pressure exceeds the setting of the valve, the pilot section opens, causing a small flow across the orifice in the main spool. The subsequent pressure drop moves the spool against a light spring opening a ring of radial holes in the sleeve, allowing relief flow to tank.
Features
High accuracy of pilot operated design. Hardened working parts give long, reliable, trouble-free life .
