該系列調(diào)節(jié)閥為了達(dá)到低噪音和防空化的目的，采用多孔式套筒取代 501G 標(biāo)準(zhǔn)型套筒。因此，除了多孔式套筒以外其余的零件都能和 501G 系列調(diào)節(jié)閥互換。
該系列如不能滿足流體條件，可選用 KOSO 多級降壓式套筒導(dǎo)向型調(diào)節(jié)閥。
This Series provides control valves that meet low noise and anti-cavitation requirements by incorporating a multi-hole type cages, instead of the standard cages, in the 501G Series cage guided control valves. All the parts except the multi-hole cage are interchangeable with the parts of the 501G Series accordingly.
For those severe fluid conditions that cannot be covered by this Series, please select KOSO multi-stage type control valves.
