| Mtundu | Chipata cha Chipata |
| Chitsanzo | Z964Y |
| Kupanikizika | Chithunzi cha PN20-50MPa 1500LB-2500LB |
| Nominal Diameter | DN 300-500 |
Amagwiritsidwa ntchito ngati zida zotsegulira ndi kutseka za makina opopera kapena machitidwe ena apamwamba ndi apakatikati a chitoliro cha 600 mpaka 1,000MW supercritical (ultra-supercritical) unit steam turbine.
- Thupi la valavu ndi boneti zimatengera mawonekedwe olumikizira apakati a flange, okhala ndi disassembly yabwino. Malekezero onse amatengera kugwirizana welded.
- The vavu chimbale utenga kukweza mtundu multisitepe chivundikiro kapangidwe.
- Mpando wa valavu umatenga kusindikiza kwa conical. Ndi zowotcherera zolimba za alloy build-up, malo osindikizira amakhala ndi cavitation komanso kukana abrasion.
- Mipikisano sitepe chivundikiro anatengera kulamulira sitepe iliyonse ya kuthamanga dontho kupanga throttled kuthamanga ulamuliro pamwamba machulukitsidwe kuthamanga kuchepetsa zimachitika cavitation ndi kung'anima evaporation.
- Ndi njira yosinthika, actuator yoperekedwa ndi valavu imatha kukhazikitsidwa malinga ndi zofuna za ogwiritsa ntchito.
