產(chǎn)品詳情
比例壓力ReliefVate設(shè)定端口1處的壓力高于設(shè)定值
由電氣控制信號(hào)定義，先導(dǎo)級(jí)打開(kāi)并允許流動(dòng)
從主活塞后部到端口2。由此產(chǎn)生的壓力不平衡導(dǎo)致主活塞逆著回油口打開(kāi)
彈簧，允許流量從端口1流向端口2。
作為電信號(hào)的函數(shù)。端口1處的釋放壓力可以無(wú)級(jí)變化。
閥門是反向控制的：閥門
電流時(shí)產(chǎn)生壓力。降低控制電流先導(dǎo)級(jí)關(guān)閉，主級(jí)關(guān)閉
在先導(dǎo)級(jí)之后，在端口1a處產(chǎn)生反壓力，例如加速風(fēng)扇的電機(jī)。
壓力可通過(guò)機(jī)械方式預(yù)先設(shè)定。
特征
專利設(shè)計(jì)，防止空化表面腐蝕鍍鋅防腐
滯后小，在整個(gè)壓力和流量范圍內(nèi)穩(wěn)定性好，動(dòng)態(tài)性能優(yōu)異
所有閥門零件均由高強(qiáng)度鋼制成，帶有硬化和研磨部件，以減少磨損和延長(zhǎng)使用壽命
線圈密封件保護(hù)電磁閥系統(tǒng)
采用一體式車身的剛性設(shè)計(jì)可減少空腔中偏心的影響，提高可靠性
CFD優(yōu)化流道的低壓降可在整個(gè)壓力范圍內(nèi)調(diào)節(jié)
