Intsimbi engathanjiswanga ihleliIvalve yeplagi yotywino olunzimazaphuhliswa kwiminyaka engama-80 eyadlulayo ukusombulula iingxaki ngeevalvu ezikhoyo kwinkonzo yokuqhekeka kwe-catalyst.Njengoko iivalvu zangaphambili kakuhle kule nkonzo kwaye kwacetyiswa ukuba zisetyenziswe kwezinye izicelo ze-hash kwimichiza kunye ne-petrochemical industry.As iivalvu zangaphambili kakuhle kule nkonzo kwaye kwacetyiswa ukuba zisetyenziswe kwezinye izicelo ze-hash kwikhemikhali kunye ne-petrochemical. ishishini.Ukucacisa ukuba kutheni i-valve ibe yimpumelelo singezantsi sichaze iimpawu zoyilo lwevalve ukubonelela ngaphakathi ngaphakathi kumandla ayo.

UMGAQO WOKUVULA NOKUVALWA KWEIvalve yeplagi yotywino olunzima

Ukuvulwa kwevalve:

• 1)jika ivili lesandla ukwenza iplagi iphakanyiswe kwaye yahlulwe ngomphezulu wokutywina;
• 2) emva koko ujike i-lever yokubamba nge-90 degree ukudibanisa itshaneli yeplagi kumjelo womzimba wevalvu, ukuze kuvulwe ivalve yeplagi.

Ukuvalwa kwevalve:

• 1) Jika intambo yokubamba nge-90 degree ukwenza umjelo weplagi ume nkqo kumjelo womzimba wevalvu
• 2) emva koko ujike ivili lesandla ukuhla iplagi, ukuze ivalve ivalwe.
