Ukulungiselela ngaphambi kokufakwa:
1. Qinisekisa ukuthi ipayipi lapho ukufakwa khonai-valve yebholaisendaweni ye-coaxial, futhi ama-flange amabili epayipini kufanele agcinwe ahambisana ukuze kuqinisekiswe ukuthi ipayipi lingathwala isisindo se-valve yebhola ngokwalo.Uma kutholakala ukuthi ipayipi alikwazi ukuthwala isisindo se-valve yebhola, hlinzeka ngokusekelwa okuhambisanayo kwepayipi ngaphambi kokufakwa.
2. Ukuqinisekisa ukuthi kukhona ukungcola, i-welding slag, njll epayipini, ipayipi kufanele ihlanzwe.
3. Hlola i-nameplate ye-i-valve yebhola, futhi wenze imisebenzi yokuvula ngokugcwele nokuvala ngokugcwele ku-valve yebhola izikhathi eziningana ukuze uqinisekise ukuthi i-valve ingasebenza ngokujwayelekile, bese uhlola ngokucophelela imininingwane ye-valve ukuze uqinisekise ukuthi i-valve iphelele.
4. Khipha ikhava yokuvikela kuzo zombili iziphetho zevalvu, hlola ukuthi umzimba wevalvu uhlanzekile yini, bese uhlanza imbobo yomzimba.Njengoba indawo yokuvala ye-valve yebhola iyindilinga, ngisho nemfucumfucu encane ingase ibangele umonakalo endaweni yokuvala.
Amanothi ngokufaka:
1. Noma iyiphi ingxenye ye-valve yebhola ingafakwa ekugcineni komfula, futhi i-valve yesibambo yebhola ingafakwa kunoma iyiphi indawo epayipini.Uma i-valve yebhola ene-actuator (efana nebhokisi legiya, i-electrical-pneumatic actuator) imisiwe, kufanele ifakwe ibheke phezulu, endaweni yokungena nokuphuma kwevalvu.endaweni evundlile.
2. Kufakwe i-gasket phakathi kwe-valve flange yebhola kanye ne-flange yepayipi ngokuvumelana nezidingo zokuklanywa kwepayipi.
3. Ama-bolts ku-flange kufanele aqiniswe ngokulinganayo, ngokulandelana futhi ngokulinganayo.
4. Uma ii-valve yebholasebenza nge-pneumatic, kagesi namanye ama-actuator, qedela ukufakwa komthombo womoya kanye nokunikezwa kwamandla ngokulandela imiyalelo.
