Burkert气动比例调节阀2873

宝德比例阀以断电时弹簧作用关闭的开关电磁阀为基础，通过改变开关电磁阀中电磁组件的结构，使弹簧力与线圈电流的电磁力相平衡。由线圈电流或电磁力的大小来决定阀芯行程或阀门开度。阀门开度与电磁力成正比。 比例电磁阀是由脉宽调制信号（PWM）控制的，该信号使线圈电流根据设定值而变化。

The baode proportional valve is based on the switch solenoid valve that the spring function shuts off when the power is off. By changing the structure of the electromagnetic component in the switch solenoid valve, the spring force is balanced with the electromagnetic force of the coil current. Determine the valve core stroke or valve opening by the size of coil current or electromagnetic force. The valve opening is proportional to the electromagnetic force. The proportional solenoid valve is colled by the pulse width modulation signal (PWM), which changes the coil current according to the set value.
