Control valves ni gaw, hpaga lam amyu myu hta hka lwi ai lam hpe hkang lu na matu ahkyak ai lit nga ai, dai gaw hkrak tup ai hte hkrak ai hku galaw lu na matu re. Control valve ni a bungli galaw lu hkra karum ya ai arung arai ni hta, lata hte lang ai lata lang ai n-gang gaw asan sha raitim, ahkyak ai atsam langai hku nna dan dawng nga ai. Ndai laika hta, hkang zing ai valve ntsa na lata hte lang ai n-gang a bungli galaw ai lam hte, galaw sa wa ai lam hpe hkang ai hta ahkyak ai lam hpe sawk sagawn ai.
1. Control Valve ni hpe sharin ya ai lam:
Control valve ni hpe sau hte wan sau kaw nna, galaw shapraw ai lam du hkra, bungli law law hta lang ma ai, dai shara ni hta hka lwi ai lam hpe hkrak hkrak hkang lu na matu ahkyak nga ai. Ndai valve ni gaw pipeline hku lai wa ai hka a n-gun hte n-gun hpe hkang ya nna, ra sharawng ai process masa ni hpe n-gun jaw na matu controller kaw na signal ni hpe htai ya ai. Automated control system ni law law nga ai raitim, lata hte galaw ai gaw, gram lajang ai lam, shadawn shadang masat ai lam, hkrit tsang hpa masa ni a matu ahkyak ai lam naw rai nga ai.
2. Control Valve langai a daw ni:
Kalang lang hkang ai valve langai hta valve hkum hkrang, actuator, positioner ni lawm ai. Valve hkum hkrang gaw hka lwi ai hpe hkang na lit nga ai rai nna, nbung, hka (sh) wan n-gun ni hte n-gun jaw ai actuator gaw hkang ai signal ni hpe madung tawn nna valve a shara hpe gram lajang ya ai. Positioner gaw valve hpe hkrak hkrak tawn da ya ai.
3. 1990 ning a lit.Lata hte galaw ai lengl:
Manual handwheel gaw actuator hta n-gun dat nna n-gun dat ai ladat langai mi re. Dai gaw, ra ai shaloi, valve a shara hpe lata hte hkang lu na matu, operator ni hpe ahkang jaw ai. Power n nga ai aten (sh) gram lajang ai aten hta, lata hte galaw ai ni gaw, valve hpaw ai hte pat ai hpe hkrak hkang lu hkra galaw ya ai.
4. Manual Handwheel a bungli galaw ai ladat:
Manual handwheel hpe laksan hku nna valve stem hte matut da nna, dai gaw valve hkum hkrang kata na valve plug hte matut da ai. Lata n-gang hpe ahkying masa hku (sh) ahkying masa hku shinggrup ai shaloi, n-gang hpe shinggrup kau ya ai majaw, valve plug gaw valve dung shara de sit sa wa nna, hka lwi ai hpe pat shingdang kau ya ai, shing nrai, dai kaw nna tsan mat wa ai majaw, hka grau law hkra lai wa lu ai. Lata hte galaw ai n-gang a shingjawng ai lam hpe linear motion de gale nna, valve a shara hpe shadut ya ai.
5. Hkyak hkyak hte gram lajang ai lam ni:
Automated system ni hkrat sum ai masa ni (sh) masing jahkrat da ai gram lajang ai aten hta, lata hte galaw ai lata hte galaw ai leng gaw manu n dan ai masa ni byin wa ai. Operator ni gaw, valve a shara hpe hkrak hkrak gram lajang na matu, handwheel hpe lang nna, dai lam hpe hkang lu ai npu hta naw nga lu hkra galaw lu ai. Ndai manual operation gaw system hkrat sum ai aten hpe pat shingdang na matu hte bungli galaw ai lam hpe n-gun n rawng hkra galaw na matu ahkyak nga ai.
6. Hkamja lam hpe myit yu ra ai lam ni:
Manual handwheel ni a hkrang hta, ahkang n lu ai (sh) n myit mada ai sha galai shai ai lam ni hpe pat shingdang na matu, laklai ai lam ni hpe law law lang bang da ai. Locking mechanism (sh) key- hte galaw ai lata leng ni gaw, laksan masat masa galaw ai ni sha, manual override hpe lang lu na matu, shimlam ladat ni hpe jai lang ai lam ni rai nga ai.
7. Automated System ni hte hpawng de ai lam:
Manual handwheel ni hpe gaw, tinang hkrai hkang ai ladat ni hte n-gun n rawng ai sha hpawng de lu hkra galaw da ai. Automated mode hta, lata n-gun gaw n shamu n shamawt ai sha nga nna, actuator gaw hkang ai signal ni hpe htang ya ai. Manual mode de galai ai shaloi, handwheel gaw hkang lu ai majaw, hkrak hkrak galai shai lu ai.
Daw dan lam:
Control valve ni a ginra hta, lata hte lang ai lata lang ai n-gang gaw, bungli galaw ai ni a matu kam mai ai hte ra kadawn ai arung arai langai hku nna magam gun nga ai. Shi a asan sha re ai lam gaw shi a ahkyak ai lam hpe nyet kau ya ai, hkrit tsang hpa lam (sh) gram lajang ai lam ni galaw ai aten hta lata hte hkang lu na matu hkrat sum ai-shim lum ai ladat hpe jaw ya ai. Industry ni matut nna rawt jat wa ai hte maren, manual handwheel gaw aten n-htum ai atsam langai mi hku nna naw nga nga ai, dai gaw gara masa hta raitim, hkang zing ai valve ni hpe hkrak tup hte hkrak hkra galaw lu na matu madi shadaw ya nga ai.
