當(dāng)P口壓力達(dá)到設(shè)定壓力后,先導(dǎo)閥芯首先被打開,
由此產(chǎn)生的壓差使得主閥芯打開,P到丅實(shí)現(xiàn)溢流。
該類型的閥反向可以承受一定的背壓,啟閉率較高,
適用于高壓力、大流量的液壓系統(tǒng)。
When the pressure at "P"reaches the valvesetting,
the pilot spool starts to open , Next the main spool
opening because of the pressure drop between inside
and outside of main spool, Realizeoverflow from P fo T.
This type of valve can withstand a certain amount of
back pressure,has high opening and closing rate
Suitable for the hydraulic system of high pressure and
large flow
