功能说明 Function description

WE型方向控制阀是电磁铁操作的换向滑阀，用以控制油液的开启、停止和流动方向。这种方向控制阀主要包括阀体（1） 一个或两个电磁铁（2）控制阀芯（3）和一个或两个复位弹簧（4）retz品牌 WE directional control valve is a reversing slide valve operated by electromagnet to control the opening, stopping and flow direction of oil. The directional control valve mainly comprises a valve body (1), one or two electromagnets (2), a control valve core (3) and one or two return springs (4)

在未通电的状态下，控制阀芯（3）由复位弹簧（4）保持在中间或初始位置（脉冲阀除外）控制阀芯（3）由湿式电磁铁（2）操作。When not energized, the control valve core (3) is held in the middle or initial position by the return spring (4) (except for the pulse valve). The control valve core (3) is operated by the wet electromagnet (2）

为了保证获得满意的操作，务必使电磁铁的压力腔充满油液 To ensure satisfactory operation, be sure to fill the pressure chamber of the electromagnet with oil

电磁铁（2）的力经过推杆（5）作用在控制阀芯（3）上、将其由静止推向所需位置，这就使油液从P至A、B至丁或P至B、A车T自由流动 The force of the electromagnet (2) acts on the control valve core (3) through the push rod (5), pushing it from static to the desired position, which makes the oil flow freely from P to A, B to D, or P to B, and A to T

当电磁铁（2）断电时控制阀芯（3）被复位弹簧（4）推向初始位置 When the electromagnet (2) is powered off, the control valve element (3) is pushed to the initial position by the return spring (4）

可选的手动应急操作（6）在电磁铁不通电的情况下可控制阀芯（3）运动 The optional manual emergency operation (6) can control the movement of the valve element (3) when the electromagnet is not energized

对于电压波动范围较大的使用场合，可选用宽电压型。如防护等级要求较高．可选用插针式防水插头 For applications with large voltage fluctuation range, wide voltage type can be selected. If the protection level is required to be higher, pin type waterproof plug can be selected

型号WE10...3X/OC...型（仅限阀芯A.C.D）Model WE10... 3X/OC... (valve element A.C.D only)这种型号是双电磁铁两位开关换向阀无定比机构无论是处于哪个位置.电磁铁其中之一必须通电.断电时无确切的切换位置 This model is a double electromagnet two position switch directional valve without a fixed ratio mechanism, no matter where it is located. One of the electromagnets must be energized. There is no exact switching position when the power is off

型号WE10...3X/OFC...脉冲阀（仅限阀芯A.C.D）Model WE10... 3X/OFC... pulse valve (valve element A.C.D only)

这种型号是双电磁铁两位开关换向阀带定位机构这样阀芯可保持在任一位置，并且电磁铁不必连续通电。插装节流塞 This model is a double electromagnet two position switch reversing valve with a positioning mechanism, so that the valve core can be kept at any position, and the electromagnet does not need to be continuously energized. Plug

型号4WE10...3X/.../B...由于切换过程中的特殊中作状态，可出现大于阀性能曲线允许的流量。在这种情况下  有必要安装插装阀节流塞。节流塞安装在方向控制阀的P口上 Model 4WE10... 3X/.../B... Due to the special working state during the switching process, the flow rate may be greater than that allowed by the valve performance curve. In this case, it is necessary to install the cartridge throttle plug. The throttle plug is installed on port P of the directional control valve.

功率极限（在使用HLP46，t=40℃±5℃时测得）Power limit (measured when HLP46 is used, t=40 ℃± 5 ℃)

所说明的换向功率极限 适用于两个方向流动时（如：从P到A 同时B到T）The stated commutation power limit applies to flow in both directions (e.g., from P to A and from B to T)

由于阀内液动力的作用，对于单一方向流动（如：从P到A.油口B封闭）允许的换向功率将明显降低 Due to the effect of the hydraulic force in the valve, the allowable reversing power for single direction flow (such as closed port B from P to A.) will be significantly reduced

换向功率极限是在电磁铁处于工作温度.电压低于标准值15%.且T口没有背压的情况下测得 The reversing power limit is measured when the electromagnet is at operating temperature and the voltage is 15% lower than the standard value, and there is no back pressure at port T
