Ukubuka konke

Amavalvu ebhola afakwe ku-trunnion aklanyelwe ukuvala umfula ongaphezulu. Umklamo wesihlalo unendlela yokukhulula imbobo ezenzakalelayo eyakhelwe ngaphakathi. Amavalvu anikezwa ukuxhumana komoya kanye nokukhipha umoya ukuze kukhishwe umoya/kukhishwe umoya emgodini wevalvu. Ukuxhumana komoya kanye nokukhipha amanzi kungasetshenziswa futhi ukuqinisekisa ukuvalwa kwevalvu ku-inthanethi.

• Isivikelo Somlilo ku-API 607

• Umklamo Ongaguquki

• Isiqu Esilwa Nokuqhuma

• Ibhola Elifakwe I-Trunnion

• Isihlalo Esithwele Intwasahlobo Esintantayo

• Umklamo Wokuvimba Okuphindwe Kabili Nokopha (DBB)

• Umzimba Ohlukanisiwe, Ukungena Kokugcina

Ukuklama Nokukhiqiza:I-API 6D, BS 5351
Ubuso Nobuso:I-API B16.10, API 6D, EN 558, DIN 3202
Ukuxhumana Okuphelile:ASME B16.5, ASME B16.25, EN 1092, GOST 12815
Ukuhlolwa Nokuhlolwa:I-API 6D, EN 12266, i-API 598

I-NSEN ilandela ngokuqinile ukulungiswa kwamahhala, ukushintshwa kwamahhala kanye nezinsizakalo zokubuyiselwa kwamahhala zingakapheli izinyanga eziyi-18 ngemuva kokuthi ivalvu isisebenzile noma izinyanga eziyi-12 ngemuva kokufakwa nokusetshenziswa epayipini ngemuva kokusebenza kwangaphambilini (okuzofika kuqala). 

Uma kwenzeka ivalvu yehluleka ngenxa yenkinga yekhwalithi ngesikhathi sokusetshenziswa epayipini ngaphakathi kwesikhathi sewaranti yekhwalithi, i-NSEN izohlinzeka ngensizakalo yewaranti yekhwalithi yamahhala. Insizakalo ngeke iphele kuze kube yilapho ukwehluleka sekulungisiwe futhi ivalvu ivame ukusebenza futhi iklayenti lisayina incwadi yokuqinisekisa.

Ngemva kokuphela kwesikhathi esishiwo, i-NSEN iqinisekisa ukuhlinzeka abasebenzisi ngezinsizakalo zobuchwepheshe ezisezingeni eliphezulu ngesikhathi noma nini lapho umkhiqizo udinga ukulungiswa nokunakekelwa.
