EATON比例阀EFV1-12V产品介绍及选型
运作方式
该阀由提供给线圈的电流控制。在零电流下，阀从端口3到端口2完全关闭。在1500 mA（12V线圈）下，阀被视为完全打开。这是在应用中使用的最大预期电流水平。端口1用于平衡阀芯和电枢的压力，在任何情况下都必须将其阻塞。最大预期压降为300 PSID。在压降高于300 PSID时，几乎没有流量增加。预期的流向是从端口3到端口2。
阀从端口2到端口3的操作将产生流量与电流和流量与压降的曲线，与从端口3到端口2的流量获得的曲线明显不同。由于阀芯和电枢是压力平衡的，因此操作压力不会影响阀门的工作特性，阀门的工作点仅由电流，压降和温度决定。
特征
硬化和磨削的工作部件可以延长使用寿命并具有良好的控制能力；紧凑的设计，低压降IP69K坚固的线圈兼容性，连续额定值。
Operation
The valve is controlled by current supplied to the coil. At zero current, the valve is fully closed from port 3 to port 2. At 1500 mA (12V coil) the valve is considered fully open. This is the maximum intended current level for use in applications.Port 1 is used for pressure balancing the spool and armature and must be blocked in all cases. The maximum intended pressure drop is 300 PSID. At pressure drops above 300 PSID, almost no increase in flow is obtained. The intended flow direction is from port 3 to port 2.
Operation of the valve with flow from port 2 to port 3 will produce flow vs current and flow vs pressure drop curves that are significantly different from those obtained with flow from port 3 to port 2. Since the spool and armature are pressure balanced, the operating pressure does not affect the operating characteristics of the valve.The operating point of the valve is determined only by current, pressure drop and temperature.
Features
Hardened and ground working parts to give long life with good control; Compact design with low pressure drop.IP69K Tough coil compatibility, continuously rated.
