HIVAL^®Kev sib cais li qub raws li API6D & ISO14313 thiab tuaj yeem siv rau hauv cov kab sib kis tau tsim raws li ASME B31.3, ASME B31.4, ASME B31.8 lossis cov qauv sib npaug.

Hankun muab ntau qhov kev sib cais li qub uas txo qis qis qis qis, suav nrog kev qhib qhib tag nrho xws li trunnion mounted pob li qub, los ntawm cov kav dej hauv lub qhov rooj, thiab qhib lub viav vias kos li qub.

Elastic & thermoplastic (soft) valve rooj zaum feem ntau yog siv los ntxuav cov kev pab cuam los yog dormant underground li qub, thaum hlau rau hlau rooj configurations yuav siv tau rau kev sib cais tseem ceeb xws li scraper launching & txais cov chaw, roj crude, thiab corrosive / qias neeg cov kev pab cuam.

HIVAL^®tej zaum yuav tau actuated nrog pneumatic actuator, tsav los ntawm cua nias, roj tshaj roj los yog actuated nrog hluav taws xob los yog hydraulic actuators, cov units muaj peev xwm muab cov kab tawg ua haujlwm thaum tau teev tseg.
