叠加板式阀。
油口布置符合ISO 4401-05-04-0-05。
用于限制两个执行器油口的主流量或先导流量。
三种调节方式：
• 带刻度的可锁定旋钮。
• 带内六角及刻度的调节螺杆。
• 带刻度旋钮。
进油节流或回油节流。
防腐蚀结构。
Z2FS 10型阀是叠加板式单向节流阀，用于限制一个或两个执行器油口的主流量或先导流量。
两个相互对称布置的单向节流阀限制一个方向的流量，并允许反向自由回流。
采用进油节流时，液压油从通道 A1 经控制边（2）与节流阀芯（3.1）形成的节流点（1），流向执行器 A2。可通过螺杆（4）轴向调节节流阀芯（3.1），以改变节流点（1）的开度。
同时，通道 A1 中的液压油经孔（5）导向活塞侧（6）。液压力和弹簧力共同使节流阀芯（3.1）保持在节流位置。
执行器B2的回油推动节流阀芯（3.2）克服弹簧（7），使其作为单向阀允许无阻流动。根据安装位置，节流作用可发生在进油或回油方向。
主油流限制
为调节执行器速度（限制主油流），节流单向阀安装在换向阀与底板之间。
先导油流量限制
用于先导式换向阀时，单向节流阀可通过限制先导流量来调节切换时间，此时安装于先导控制阀与主阀之间。
