Chigadzirwa chacho chinoshandiswa kudhiza-mvura sisitimu yebhailer kana chiutsi turbine yemagetsi emagetsi supercritical (ultra-supercritical) unit.
- Iyo valve body inotora yakazara forged chimiro.
- Chisimbiso mhando yemuviri wevharuvhu uye bhoneti inotora kudzvanywa kwekuzvivharira chimiro.
- Chisimbiso pamusoro pechigaro chevharuvhu chine Stellite 6 alloy kuvaka-up welding.
- Chisimbiso pamusoro pevhavha disc ine Stellite 12 alloy kuvaka-up welding.
- Iine curb (kana annular pressure yekudzikisa groove) kumberi kwayo, nzvimbo yekuvharisa inogona kudzivirira chidimbu uye kusachena mumapombi kubva pakupwanya nzvimbo yekuvharira pakuvhara vharafu.
- Chikamu chekuisa chisimbiso chinotora maviri-nhanho throttle element kudzvanya kudzikisa chimiro uye yepakati kudzvanywa kunoderedza nhanho nenhanho kudzivirira cavitation uye scouring kubva mukukuvadza chisimbiso chepamusoro.
