Rexroth力士樂(lè)R900589603先導(dǎo)式溢流閥DB20?1?5X/100現(xiàn)貨，上海彥西正品供應(yīng)

力士樂(lè) R900589603 DB20?1?5X/100 屬于 DB 系列 NG20 先導(dǎo)式溢流閥，板式底板安裝，由主閥與先導(dǎo)調(diào)壓閥組成二級(jí)先導(dǎo)結(jié)構(gòu)。主要用于液壓系統(tǒng)限定系統(tǒng)壓力，起到穩(wěn)壓、過(guò)載安全保護(hù)作用，系統(tǒng)壓力超出設(shè)定值自動(dòng)溢流卸油回油箱，保護(hù)油泵、油缸、管路不受超壓損壞，廣泛用于液壓站、壓機(jī)、注塑設(shè)備，適配設(shè)備維修替換與新項(xiàng)目配套。

核心參數(shù)

訂貨型號(hào)：R900589603 完整型號(hào)：DB20?1?5X/100 產(chǎn)品類型：先導(dǎo)式溢流閥 通徑規(guī)格：NG20 安裝形式：板式底板安裝 設(shè)定壓力：100bar 最高工作壓力：315bar 最大流量：400L/min 密封材質(zhì)：NBR 丁腈橡膠 工作介質(zhì)：液壓油 HL、HLP 等 油溫范圍：?20℃ ~ +80℃ 油液粘度：10?500mm2/s 調(diào)節(jié)方式：手輪調(diào)節(jié)，帶鎖緊螺母

產(chǎn)品優(yōu)勢(shì)

先導(dǎo)二級(jí)結(jié)構(gòu)，壓力控制精度高，壓力波動(dòng)小，大流量工況工作穩(wěn)定。 手輪調(diào)壓配置鎖緊螺母，鎖緊設(shè)定壓力，防止設(shè)備震動(dòng)造成壓力漂移。 球墨鑄鐵閥體，強(qiáng)度高抗沖擊，適配工業(yè)現(xiàn)場(chǎng)長(zhǎng)期連續(xù)運(yùn)行工況。 標(biāo)準(zhǔn) NG20 板式安裝尺寸，通用性強(qiáng)，拆裝更換便捷。 內(nèi)部閥芯精密配合，內(nèi)泄漏小，降低系統(tǒng)發(fā)熱與能耗。 具備遠(yuǎn)程控制油口，可外接遠(yuǎn)程調(diào)壓，拓展控制方案。
