The proportional pressure valve uses piezo elements and semiconductor sensors. According to the adjustment of the electrical proportional signal, it can achieve stepless control of the outlet gas pressure with high-precision, high-response, and no noise.
The flow proportional valve uses piezoelectric elements and semiconductor sensors. According to the adjustment of the electrical proportional signal, it can achieve continuous control of the outlet gas flow with high-precision, high-response, and no noise.
