Ivalve yendlela ezintathu yokudambisa ibandakanya umzimba wevalve ezimbini, idiskhi yevalve ezimbini, isihlalo sevalve ezimbini, itee enye, kunye nesilinda esi-4. Umzimba wevalvu wahlulwe waba yimingxuma emithathu A, B, kunye no-C edityaniswe ngaphandle ngesitulo sepleyiti yevalve. Isixhobo sokutywina sifakwe phakathi komzimba wevalvu kunye nesihlalo sepleyiti yevalve. Iplate yokucoca umoya kwi-cavity ixhunyiwe kwi-cylinder ngokusebenzisa i-shaft yokudibanisa. Ngokutshintsha indawo yepleyiti yevalve, indlela yokuhamba kwegesi kumbhobho ingatshintshwa; Ngenxa yokutshintshana kobushushu ngomzimba wokugcina i-thermal, ukushisa okusebenzayo kwe-valve yokubuyisela umva kuncinci, kwaye akukho mfuneko ekhethekileyo yezinto eziphathekayo ze-valve.

Nangona kunjalo, ngenxa yeemfuno zemveliso eqhubekayo, i-valve yokubuyisela i-valve idinga ukunqoba ukuguga kunye nokukrazula okubangelwa uthuli lwegesi ye-flue kunye nemiphumo ephazamisayo. Amalungu omatshini kufuneka aqinisekise ukuguga kunye nokukrazula okubangelwa ukutshintshwa rhoqo kwamacandelo, okuye kwafuna ukuthembeka okuphezulu kunye nobomi bokusebenza.
