美國(guó)派克PARKER液壓閥[PARKER換向閥]Parker派克D3W/D3DW系列帶電感位置控制電磁換向閥是一種通過(guò)電磁鐵直接操縱的帶電感位置控制的2位4通換向閥，可被用作監(jiān)控閥?？梢杂羞x擇的對(duì)初始位置或終點(diǎn)位置進(jìn)行監(jiān)控。只有單電磁鐵閥可以用于位置控制。斷電時(shí)換向閥的可靠位置為初始位置，其通過(guò)復(fù)位彈簧來(lái)保持的。美國(guó)派克PARKER液壓閥液壓閥（即控制元件）在液壓系統(tǒng)中控制和調(diào)節(jié)液體的壓力、流量和方向。根據(jù)控制功能的不同，液壓閥可分為村力控制閥、流量控制閥和方向控制閥。壓力控制閥又分為益流閥（安全閥）、減壓閥、順序閥、壓力繼電器等;流量控制閥包括節(jié)流閥、調(diào)整閥、分流集流閥等;方向控制閥包括單向閥、液控單向閥、梭閥、換向閥等。根據(jù)控制方式不同，液壓閥可分為開(kāi)關(guān)式控制閥、定值控制閥和比例控制閥。
液壓閥可分為普通液壓控制閥、伺服控制閥、比例控制閥。根據(jù)安裝形式不同，液壓閥還可分為管式、板式和插裝式等若干種。
液壓閥的基本結(jié)構(gòu)主要包括閥芯、閥體和驅(qū)動(dòng)閥芯在閥體內(nèi)做相對(duì)運(yùn)動(dòng)的操縱裝置。閥芯的主要形式有滑閥、錐閥和球閥；閥體上除有與閥芯配合的閥體孔或閥座孔外，還有外接油管的進(jìn)、出油口和泄油口；驅(qū)動(dòng)閥芯在閥體內(nèi)做相對(duì)運(yùn)動(dòng)的裝置可以是手調(diào)機(jī)構(gòu)，也可以是彈簧或電磁鐵，有些場(chǎng)合還采用液壓力驅(qū)動(dòng)。 美國(guó)派克PARKER液壓閥在工作原理上，液壓閥是利用閥芯在閥體內(nèi)的相對(duì)運(yùn)動(dòng)來(lái)控制閥口的通斷及開(kāi)口的大小，以實(shí)現(xiàn)壓力、流量和方向控制。液壓閥工作時(shí)，所有閥的閥口大小、閥進(jìn)、出油口間的壓差以及通過(guò)閥的流量之間的關(guān)系都符合孔口流量公式（q＝KA·Δp m），只是各種閥控制的參數(shù)各不相同而已。
