产品说明设置
设置
2WFCE 型先导式比例方向阀基本构成包括：盖 (1)主级 (2)带比例电磁铁 (3) 的先导控制阀带位置传感器和模拟接口的集成电子元件 (4)集成电子元件 (OBE) 将****控制值与主级 (2) 控制阀芯的位置理论值进行比较。在存在控制偏差的情况下，先导控制阀 (3) 将激活控制线圈。以此调节控制阀芯。根据控制偏差的不同，主级 (2) 控制腔或者以先导油（主级已关闭）加压，或者已卸载（主级已打开）。控制偏差修正前，将通过控制值成比例地控制行程及节流孔横截面。 为保证正常运行，必须遵守以下条件：流向 A → B（X 连接到 A）流向 B → A（X 连接到 B）

集成电子元件 (OBE)功能
1. 接通程序/故障特性施加 24 ?V 的电源电压之后，如果满足以下条件，则电子元件将准备就绪：电源电压 UB > 18 V DC 线圈连接未中断控制值线未中断且控制值 > 2.7 mA（仅指接口“G1”）如果上述条件中有一个未得到满足，则控制器和输出级断路，并将插脚 11 （仅指接口“B1”和“G1”）的“准备就绪”信号设置为 0 V。

2. 理论值输出信号
电气接口“A1”（插脚 F）和“B1”（插脚 6）“A1”：0.35 V ... 10 V 对应于 0 % ... 100 % 的阀门开口；当理论值 
< -2.5 V 时，节流阀芯处于阀座位置“B1”：0 V ... 10 V 对应于 0 % ... 100 % 的阀门开口；当理论值 < -1.5 V 时，节流阀芯处于阀座位置电气接口“G1”（插脚 6）4 mA ... 20 mA 对应于 0 % ... 100 % 的阀门开口；当理论值 < 2.7mA 时，节流阀芯处于阀座位置

注意：
电子元件接口“A1”在开口方向：若控制值 ≥ 0.5 V 时，则启用阀门在闭合方向：控制值 ≤ 0.3 V 时（“阀座上”），阀门停用在开口方向的电气接口“B1”和“G1”：若已设置使能插脚 3，控制值 > -1 V（“B1”）或 > 2 mA（“G1”），则启用阀门在闭合方向：若未设置插脚 3，控制值 < -1 V（“B1”）或 < 2 mA（“G1”）（“阀座上”），则停用阀门

比例阀是一种新型的液压控制装置。在普通压力阀、流量阀和方向阀上，用比例电磁铁替代原有的控制部分，按输入的电气信号连续地、按比例地对油流的压力、流量或方向进行远距离控制。比例阀一般都具有压力补偿性能，输出压力和流量可以不受负载变化的影响

阀对流量的控制可以分为两种：
一种是开关控制：要么全开、要么全关，流量要么较好、要么最小，没有中间状态，如普通的电磁直通阀、电磁换向阀、电液换向阀。
另一种是连续控制：阀口可以根据需要打开任意一个开度，由此控制通过流量的大小，这类阀有手动控制的，如节流阀，也有电控的，如比例阀、伺服阀。
所以使用比例阀或伺服阀的目的就是：以电控方式实现对流量的节流控制（当然经过结构上的改动也可实现压力控制等），既然是节流控制，就必然有能量损失，伺服阀和其它阀不同的是，它的能量损失更大一些，因为它需要一定的流量来维持前置级控制油路的工作。
