Selemong se fetileng, re hlokometse hore tlhoko ea valve e kholo ea serurubele e eketsehile haholo, boholo bo ikhethang ho tloha ho DN600 ho ea ho DN1400.

Hobane sebopeho sa valve ea serurubele se loketse haholo ho etsa li-valve tse kholo, tse nang le sebopeho se bonolo, bophahamo bo bonyenyane le boima bo bobebe.

Ka kakaretso, li-valve tsa serurubele tse bophara bo boholo li sebelisoa liphaepheng tsa likhoerekhoere, liphaepheng tsa oli, liphaepheng tsa phepelo ea metsi, mererong ea paballo ea metsi, kaho ea masepala le libakeng tse ling. Hona joale liphaephe tsa metsi tse potolohang li fetoleloa ho litiiso tse thata tse tharo tse sa tloaelehang, ka lebaka la bophelo ba tsona bo bolelele ba tšebeletso le tlhokomelo e sa hlokeng.

NSEN e se e loketse ho romela sehlopha sa di-valve tse nang le di-valve tsa boholo ba DN600 le DN800 bekeng ena, tlhahisoleseding ya bohlokwa e ka tlase;
