德國Rexroth三位四通伺服換向閥4WRLE的功能說明：當沒有操動控制電磁鐵時，先導閥的控制滑閥在彈簧力作用  下處在“Fail-Safe”功能位置中，主級滑閥處在其彈簧對中的中  間位置。  在集成電子控制器中將設定值與主級控制滑閥的位置實際值  進行比較。 如果存在控制偏差，就會驅動控制電磁鐵，  以改變磁力的方式對先導滑閥進行調整。 經過控制截面的體  積流量使得主控制滑閥移動，相對于設定值 0.5...10 V   以 20...100％ 比例調節其行程。 如果設定值 ＜±0.5 V，  則主級的控制滑閥就會在對中彈簧作用下保持在被遮蓋的中  間位置。  要么在內部通過接口 P，或者在外部通過接口 X 將控制油供  應給先導閥。 可以在內部通過接口 T 或者在外部通過接口 Y   回流到油箱。

電源故障  如果發生故障，或者當電纜斷線時，集成式電子控制器就會  將控制電磁鐵斷電，先導滑閥進入“Fail-Safe”功能位置，  并且將主級的控制油腔卸空。 主級控制滑閥在彈簧作用下進  入中間位置。
