EATON安全閥RV11-12系列介紹
操作
當(dāng)進(jìn)口壓力超過閥門設(shè)定值時，先導(dǎo)部分打開，使小流量通過主閥芯的節(jié)流孔。隨后的降壓使閥芯移動到一個輕彈簧上，打開套筒上的徑向孔環(huán)，允許泄流入罐。
特點
高精度的先導(dǎo)操作設(shè)計。硬化的工作部件被賦予長期，可靠，無故障的使用壽命。
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 .
