Burkert氣動比例調(diào)節(jié)閥2873

寶德比例閥以斷電時彈簧作用關(guān)閉的開關(guān)電磁閥為基礎(chǔ)，通過改變開關(guān)電磁閥中電磁組件的結(jié)構(gòu)，使彈簧力與線圈電流的電磁力相平衡。由線圈電流或電磁力的大小來決定閥芯行程或閥門開度。閥門開度與電磁力成正比。 比例電磁閥是由脈寬調(diào)制信號（PWM）控制的，該信號使線圈電流根據(jù)設(shè)定值而變化。

Burkert氣動比例調(diào)節(jié)閥2873

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.
