Isetshenziselwa ukulawula okusethiwe ngaphambili kokugeleza kwamapayipi, lolu chungechunge lwemikhiqizo lusetshenziswa kakhulu ukuxazulula inkinga yokungalingani kwe-hydraulic kunethiwekhi yokudlulisela nokusabalalisa uketshezi.Ngokusho kokuhlelwa kwesistimu, kunqunywa ukuthi ukunikezwa kwamanzi kwegatsha kuhlala njalo ngaphansi kwesisekelo sokuvuleka okuhlukene nokuhluka kwengcindezi.
I-valve yokulinganisa ye-KMF iletha ukusebenza okunembile kwe-hydronic kuhlelo oluhlaba umxhwele lwezinhlelo zokusebenza.Ifaneleka kahle ukuthi isetshenziswe ohlangothini lwesibili kumasistimu okushisa nawokupholisa, namasistimu wamanzi ampompi.

Indawo enguziro ilinganiselwe futhi akufanele ishintshwe.
Ijika (Fig. 1) livumelekile kuma-valve anezinsimbi ezivamile zamapayipi (Fig.2).Zama futhi ukugwema ukufaka ompompi namaphampu, ngokushesha ngaphambi kwe-valve.
Fig.2
Lungisa isikali sesondo lesandla ngokuya ngezidingo zokuklama.
Imishini yokukhipha umoya kufanele ifakwe kumapayipi esistimu, futhi isistimu ingaqukatha umoya, okungase kubangele ukuvinjelwa kwemidiya, ukwehluleka komsebenzi wokulungisa, noma umsindo omkhulu;
Kunconywa ukwengeza isihlungi noma ukuhlanza ipayipi endaweni yokungena kwamanzi ye-valve ukugwema izinhlayiya ezinkulu zokungcola ezivimbela isici sokulawula i-valve;
Naka ukuvikelwa kwembobo yokuthola, uma ithintwa noma ikhubazekile, izodala ukuvuza noma ukulungisa okunzima esikhathini esizayo.
Lungisa isikali sesondo lesandla ngokuya ngezidingo zokuklama.
Le valve inomsebenzi wokusetha kuqala izinga lokugeleza eliphezulu.Sebenzisa i-wrench ene-hexagonal ukuze uzungezise umkhawulo womkhawulo wokuvula ngokuhambisana newashi, ukuze umkhawulo wokuvuleka kwe-valve, futhi ukugcinwa kwesistimu okulandelayo ngeke kudinge ukususa iphutha.
I-valve yebhalansi ingasetshenziswa yodwa ukulawula ukugeleza kwesistimu, noma ingasetshenziswa ngokuhambisana ne-valve yokucindezela okuhlukile.Lapho i-valve ifakiwe, isiqondiso sokugeleza kwamanzi kufanele sihambisane nesiqondiso somcibisholo ku-valve.Ukuze uqinisekise ukunemba kwesilinganiso, sicela uqinisekise ukuthi kunezigaba zamapayipi eziqondile ngaphambi nangemuva kwevalvu(Fig.2)
