德(de)國HYDAC Technology GmbH 專業生產(chan)用于(yu)流體(ti)過(guo)濾技(ji)術、液(ye)壓控制(zhi)技(ji)術、電(dian)子(zi)(zi)測量技(ji)術的元件和裝(zhuang)置,是世界 的過(guo)濾器(qi)(qi)、蓄能器(qi)(qi)、液(ye)壓閥(fa)、電(dian)子(zi)(zi)產(chan)品、管夾、電(dian)磁鐵、液(ye)壓系統總(zong)成等(deng)產(chan)品的液(ye)壓件制(zhi)造商。
德(de)國賀德(de)克(ke)HYDAC電液(ye)(ye)比例控(kong)(kong)制(zhi)(zhi)閥是液(ye)(ye)壓傳動和(he)液(ye)(ye)壓伺服(fu)系統的(de)發展,生產實踐中出(chu)現一(yi)些(xie)即要(yao)求(qiu)能(neng)夠連續的(de)控(kong)(kong)制(zhi)(zhi) 壓力、流量和(he)方(fang)向,又不需要(yao)其控(kong)(kong)制(zhi)(zhi)精(jing)度(du)很 高的(de)液(ye)(ye)壓系統。由于(yu)普(pu)通(tong)的(de)液(ye)(ye)壓元件不能(neng)滿 足具有一(yi)定(ding)的(de)伺服(fu)性要(yao)求(qiu),而使用(yong)電液(ye)(ye)伺服(fu) 閥又由于(yu)控(kong)(kong)制(zhi)(zhi)精(jing)度(du)要(yao)求(qiu)不高而過于(yu)浪費,因 此近幾年產生了介于(yu)普(pu)通(tong)液(ye)(ye)壓元件 (開(kai)關控(kong)(kong)制(zhi)(zhi)) 和(he)伺服(fu)閥之間(jian)的(de)比例控(kong)(kong) 閥,電液(ye)(ye)比例控(kong)(kong)制(zhi)(zhi)閥(簡稱比例閥)實質上(shang)是一(yi)種廉價的(de)、抗(kang)污染性能(neng)較好(hao)的(de)電液(ye)(ye)控(kong)(kong)制(zhi)(zhi)閥。
