Kaja wa hpaw da ai pneumatic solenoid valve ngu ai gaw, shi a default (sh) normal state hta hpaw nga ai raitim, wan n-gun signal hpe bang ai shaloi pat kau mai ai. Pneumatic solenoid valves ni gaw, nbung laru (sh) kaga nbung ni hpe pneumatic system ni hta hkang lu na matu lang ai jak ni re. Shanhte hpe bungli galaw ai lam amyu myu hta jai lang nna, galaw sa wa ai lam ni hpe galaw na matu jai lang ma ai.
Kaja wa hpaw da ai (NO) hkrang masa hta, valve gaw solenoid hpe n bang ai sha, nbung (sh) gas hpe lai di lu ai. Solenoid hpe jaw ai shaloi, wan n-gun hpe n-gun jaw nna, nbung (sh) gas lwi ai hpe pat da ai, valve hpe pat kau ya ai.
Dai solenoid gaw electromechanical jak rai nna, core langai a grup yin hta wire hkala ai coil langai mi lawm ai. Coil hku nna wan n-gun langai mi lwi pru wa ai shaloi, core hpe shamu shamawt shangun ai magnetic field hpe shapraw ya nna, valve mechanism hpe shamu shamawt shangun ai. Solenoid de wan n-gun hpe hkang lu ai hku nna, operator ni gaw valve hpe tsan tsan kaw nna hpaw (sh) pat kau lu ai, pneumatic system ni hta automation hte control galaw na matu ladat langai mi hpe jaw ya lu ai.
