A valvecu ti hri caah uknak thilri a si. A hrampi rian cu pipeline ring i a kalnak kha pehtlaih asiloah khenh, a luannak lam thlen, medium a luannak le a luannak remh, le pipeline le thilri hna i a ttha tein riantuan ning kilven kha a si.
一．Valve pawl thleidannak
A hmannak le a riantuannak ning in tthen khawh a si:
1. Kharnak valve: pipeline thilri kha tan asiloah peh. Cu hna cu: gate valve, globe valve, ball valve, butterfly valve, diaphragm valve, plug valve.
2. Check valve: pipeline chung i a ummi thilri kha a hnulei ah a luang lonak hnga kham.
3. Phawtzamhnak valve: thilri a luannak lei kha thlen, thilri kha phawtzamh, tthen asiloah cawh. Cu hna cu phawtzamhnak valve, meikhu tlaihnak, le lam pathum in a kalmi ball valve hna an si.
4. Uknak valve: a ummi thilri hna i an hneknak le a luannak kha remh. Cu hna cu hneknak zorternak valve, uknak valve, throttle valve tibantuk an si.
5. Himnak valve: thilri chung i a tlawm deuhmi thli nih a langhtermi man a lonh nakhnga lo kham, cun a tam tukmi himnak kilvennak pek.
二. A hrampi tahfung hnavalve
1. Valve (DN) i a min in a kauhnak.
2. Valve (PN) i a tlawmbik thlihrannak.
3. Valve i a ritmi le a lumternak tahfung: Valve riantuannak a lumternak nih a tlawmbik pressure a lonh tikah, a riantuan ning a sangbik cu aa tlak ning in tlawmter a hau.
4. Valve pressure unit thlennak:
| CACAWNNAK KHAAN | 150 | 300 | 400 | 600 | 800 | 900 | 1500 | 2500 |
| MPa | 1.62.0 | 2.54.05.0 | 6.3 | 10 | 13 | 15 | 25 | 42 |
5. A hman khawhmi lamvalve:
Industrial valve cu petroleum, chemical industry, thir sernak, electric thazaang, nuclear thazaang le a dang industry hna ah hman a si. A kalmi media hna cu gas (thli, meikhu, ammonia, lungmeihol gas, petroleum gas, natural gas, tbk.); ti (ti, ti ammonia, chiti, acid, alkali, tbk.). Cheukhat cu meithal bantuk in a rawk khomi an si, cun a cheu cu radioactive a tam tukmi an si.
