J41H / Y flange ntiaj teb valve

Cov yam ntxwv ntawm J41H / y flange globe valve 1. Cov khoom lag luam muaj cov qauv tsim nyog, kev ruaj ntseg sealing, kev ua haujlwm zoo heev thiab zoo nkauj tsos; 2. Lub sealing nto overlaid nrog Co raws li cemented carbide tau zoo hnav tsis kam, corrosion kuj, abrasion kuj thiab lub neej ntev kev pab cuam; 3. Lub qia valve muaj corrosion kuj zoo thiab khawb tsis kam tom qab quenching thiab tempering thiab nto nitriding kho; 4. Lub valve yog nruab nrog rov qab sealing qauv, uas yog txhim khu kev qha; 5. Cov khoom siv thiab flange loj tuaj yeem xaiv tau raws li kev ua haujlwm tiag tiag lossis cov neeg siv khoom kom tau raws li ntau yam kev xav tau ntawm engineering.
