Valve ea Bolo ke Eng
Valve ea bolo e sebelisa bolo e se nang letho, e potolohang e nang le mokoti ho laola phallo ea mokelikeli. Ha mokoti oa bolo o tsamaellana le phaephe, mokelikeli o phalla ka bolokolohi; ho reteleha ha likhato tse 90 ho thibela phallo ka botlalo. Li-valve tsa bolo tse nang le khoele li na le likhokahano tsa screw-end (likhoele tsa NPT kapa BSP), e leng se etsang hore li be ntle bakeng sa litsamaiso tsa khatello tse tlase ho isa bohareng liphaepheng tsa metsi, HVAC le liindastering.
