I I-AWWA C515 Flange Type Ductile Iron Resilient Seated Gate Valve Yakhelwe isevisi yokuvala ethembekile ekuhlinzekweni kwamanzi kamasipala, ekuhlanzweni kwamanzi amdaka, ekuniseleni, nasezinhlelweni zokuvikela umlilo. Yakhiwe ngokuhambisana ne-AWWA C515 ejwayelekile, ivalvu inomzimba wensimbi oqinile ohlanganiswe ne-EPDM noma i-NBR wedge eqiniswe ngokuphelele, eqinisekisa ukuvalwa okungenamagwebu kanye ne-torque ephansi yokusebenza.

I-valve yesango elihlala liqinile uhlobo lwe-valve evame ukusetshenziswa ekusakazweni kwamanzi nasezinhlelweni zamanzi angcolile ukulawula ukugeleza kwamanzi noma olunye uketshezi. Isici esiyinhloko sale valve yisihlalo sayo esiqinile, esivame ukwenziwa ngezinto ezithambile ezifana nerabha noma izinto zokwenziwa, ezenzelwe ukuhlinzeka ngokuvala okuqinile, okungavuzi lapho i-valve ivaliwe. I-valve iqukethe isango (noma i-wedge) ehamba phezulu naphansi ngaphakathi komzimba we-valve. Lapho isango liphakanyisiwe, livumela uketshezi ukuthi ludlule ku-valve, futhi uma lehliswa, isango livala isihlalo esiqinile ukuze livimbele ukugeleza. Isihlalo esiqinile siqinisekisa ukusebenza kahle kokuvala, ikakhulukazi ezimweni lapho kungase kube nokungahambi kahle emzimbeni we-valve noma esangweni. Ama-valve esango ahlala liqinile aziwa ngokuqina kwawo, ukulula kokusebenza, kanye nokugcinwa okuphansi. Ngokuvamile asebenza ngesandla kusetshenziswa isondo lesandla noma ngokuzenzakalelayo ezinhlelweni eziyinkimbinkimbi kakhulu.
