• Mgbakọ diski-nsị nke e ji ígwè rụọ maka nhazi
• Ike elu (mkpuchi Stellite 6) maka iguzogide nkụchi

4. Akara nke abụọ (Nkwado ndabere)

• Mgbaaka ngwugwu graphite n'okpuru bellows dị ka ihe na-adịghị mma maka ọdịda

Kedu otu valvụ Globe Seal nke dị na bellow si arụ ọrụ

Nzọụkwụ 1: Imepe Valvụ

Mgbe a na-atụgharị wiil aka ahụ n'akụkụ aka ekpe:

• Ogwe ahụ na-ebili, na-ebuli diski ahụ n'oche ahụ
• Bellows na-agbanye aka n'akụkụ axial, na-ejigide iguzosi ike n'ezi ihe nke akara

Nzọụkwụ nke 2: Imechi Valvụ

Mgbanwe elekere:

• Ọkpụkpụ ahụ na-amanye diski ahụ megide oche, na-akwụsị mmiri
• Mkpọda na-agbatị ruo ogologo mbụ

Nzọụkwụ nke 3: Mgbochi Ntapụ mmiri

Ọrụ mkpuchi okpukpu abụọ:

• Akara mbụ: Ụzọ ntapu mmiri nke ogwe osisi bellows
• Akara nke abụọ: Nkwakọba graphite (dabara na API 622)

Uru Karịrị Valvụ Globe Ọkọlọtọ
