Manual valve ngu ai gaw, jak hte jak rai ni hta lang ai, lata hte lata hte galaw ai valve langai mi rai nga ai. Madung lata,lata lengclockwise shinggrup ai lam hpe lajang ya ai thorium ni ai maga de, clockwise shinggrup ai lam hpe hkang na matu hpaw ai maga de nhtang wa ai lam. Raitim, nkau mi a valve hpaw nna pat ai gaw n bung ai maga de rai nna, operation garai n galaw shi yang, operation galaw ngut ai hpang hpaw ai hte pat ai hpe sadi maja ra ai.
Manual valve a kaba ai, lata hte .lata lengngu ai hpe shinggyim masha langai mi galaw da ai. Dai majaw, valve hpe jai lang na matu masat da ai: operator wa gaw valve hpe hpaw nna pat na matu lever hte long wrench lang na ahkang n nga ai. Dai aten hta, lata n-gang a galu kaba ai hte lata n-gang a diameter gaw 320mm npu rai yang, marai langai sha galaw lu ai. 320mm hte maren (sh) dai hta jan ai diameter nga ai handwheel gaw masha lahkawng rau galaw lu ai, shing nrai marai langai hpe hkrak ai lever hte galaw lu ai (general length gaw 0.5m hta n jan ai). Raitim diaphragm valve, non metal valve ni hpe gaw lever (sh) spanner galu lang na matu tsep kawp pat hkum da ai, n-gun kaba, grai law ai n-gun hte valve hpe pat na matu ahkang n jaw ai.
Nkau mi gaw lever hte long spanner hpe lang nna manual valve hpe galaw ai, hpaw ai n-gun grau kaja ai shaloi, teng sha n re. Dai gaw aten garai n du yang valve hpe hkra machyi shangun nna, accident pyi byin shangun na re. Practice hku yu yang: percussive hand wheel hta n-ga, akajawng sha grai kaba ai grai loi ai majaw valve handwheel a bungli galaw ai lam hpe hkra machyi shangun ai, lata, stem hte sealing ntsa na abrasions ni, sealing ntsa hpe pyi hkra machyi shangun ai. Lahkawng ngu na hta, .lata leng, handle hten za ai (sh) n nga mat ai rai yang, alawan jahpring ra ai, wrenches hpe kaga hku lang na ahkang n jaw ai.
Gate valve hte globe valve zawn re ai valve ni hpe ntsa de hpaw ai (sh) hpaw ai shaloi 1/4~1/2 de galai ra ai (dai gaw, lawu na dead point (sh) ntsa dead center), dai hku nna thread hpe grau kaja hkra pat da lu na re, dai hku nna valve hpe grai n-gun n ja hkra n hkrat sum hkra, akyu rawng ai hku galaw ai shaloi jep yu lu na re.
Caliber kaba ai hka htung ni, gate hka htung ni hte cut-off hka htung ni hpe bypass hka htung ni hte rau jaw da ai. Bypass valve a bungli gaw, dut shabra ai hte dut shabra ai pressure shai hkat ai hpe rap ra hkra galaw ya ai, hpaw ai aten hpe shayawm ya ai. Bypass valve hpe shawng hpaw nna, valve kaba hpe hpaw dat u.
