美國派克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，其通過復(fù)位彈簧來保持的。美國派克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)來控制閥口的通斷及開口的大小，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。
