Rexroth力士樂(lè )SV 6 PA2-6X/單向閥
SV 型單向閥是用于底板安裝的先導式單向閥。用于一個(gè)執行機構油口的無(wú)泄漏阻塞，甚至能夠用于長(cháng)期停機的情況。
該閥主要由殼體 (1)、提升座閥 (2)、壓縮彈簧 (3)、控制閥芯 (4) 以及可選預開(kāi)口球座閥 (7) 組成。
座閥允許流體從方向 A 流向 B，而無(wú)需外部先導壓力。
條件： pA > pB + 開(kāi)啟壓力（壓縮彈簧）。在相反方向上，座閥以液壓方式緊閉。
油口 X 處的高先導壓力足以使控制閥芯 (4) 沿座閥方向移動(dòng)，并推動(dòng)提升座閥 (2) 離開(kāi)其閥座。這便實(shí)現了兩個(gè)方向上的自由流動(dòng)（主動(dòng)保持打開(kāi)）。
為確保座閥主動(dòng)打開(kāi)，控制閥芯 (4) 兩側上的壓力比與提升座閥 (2) 或 (7) 上的面積比同樣重要。
因此，提供了以下不同類(lèi)型
SV（連接至 pA 的大閥芯端面 A2 (6)）或 ?
以及帶預開(kāi)口“A”和不帶預開(kāi)口“B”的型號。
型號“A”（帶預開(kāi)口）
該閥配有一個(gè)附加的預開(kāi)口。通過(guò)對油口 X 加壓，控制閥芯 (4) 將向右移動(dòng)。這樣一來(lái)，滾珠 (7) 和提升座閥 (2) 將先后被推出閥座。
注意！
型號“A”：
由于使用的是具有擴大的開(kāi)口控制面積比的兩層結構，使用較低的先導壓力也可以安全卸載。 ?
避免由于執行機構側的壓力容積的衰減降壓而導致的換向沖擊。 ?
型號“B”：
閥門(mén)不帶預開(kāi)口時(shí)，可能會(huì )突然卸載所含的壓力容積。產(chǎn)生的換向沖擊不但會(huì )導致安裝組件的過(guò)早磨損，還會(huì )形成噪音。 ?
替換插頭 (9) 和 (10) 可實(shí)現從 SV 型號到 SL 型號的修改。必須始終安裝其中一個(gè)插頭！
