Izihlalo ze-Tungsten carbide, njengezingxenye eziyinhloko zokuvala ama-valve, zithatha isikhundla esibalulekile emkhakheni wezimboni ngenxa yezimpawu zazo zokusebenza. Ngokwakheka kwaso okuyingqayizivele, i-tungsten carbide, isihlalo sibonisa ukuqina nokuzivumelanisa nezimo, okusenza sibe yisinqumo sokuqala sezinhlelo zokusebenza eziningi zezimboni.
Okokuqala, izihlalo ze-tungsten carbide zaziwa ngobulukhuni bazo obukhulu nokumelana nokugqoka. Ezindaweni zemidiya ezicindezelayo, ezihamba ngesivinini esiphezulu, izinto zezihlalo zendabuko zivame ukuba nzima ukumelana nokuguguleka nokugqoka isikhathi eside, kuyilapho i-tungsten carbide ingamelana ngokuphumelelayo nokuguguleka kwalezi zimo ezinzima ngenxa yezakhiwo zayo ezinhle kakhulu zomzimba. Lokhu kwenza izihlalo ze-carbide zibe zinhle ngokwemibandela yokwelula impilo ye-valve kanye nokunciphisa izindleko zokuyilungisa.
Okwesibili, ukumelana nokugqwala nakho kuyisici esivelele sesihlalo se-carbide. Ezimbonini zamakhemikhali, zikaphethiloli nezinye, okuphakathi nendawo okugeleza epayipini kuvame ukugqwala kakhulu, okubeka phambili izidingo eziphezulu kakhulu zempahla yesihlalo samavalvu. Ngokuzinza kwayo kwamakhemikhali okuhle kakhulu, i-tungsten carbide ingasebenza ngokuzinza isikhathi eside kulezi zindawo ezinokhahlo ngaphandle kokugqwala nokulimala, iqinisekisa ukuphepha nokuthembeka kwesistimu ye-valve.
Ngaphezu kwalokho, isihlalo se-carbide sinokumelana okuhle nokushisa okuphezulu. Ezinqubweni eziningi zezimboni, izinga lokushisa eliphakathi lingakhuphuka kakhulu, elibekela inselele ukumelana nokushisa kwempahla yokuhlala. Ngephuzu layo eliphezulu lokuncibilika kanye nokuzinza okuphezulu kokushisa, i-carbide enosimende ingagcina ukusebenza okuzinzile endaweni yokushisa ephezulu, ngaphandle kokuguqulwa nokuqhekeka, ukuqinisekisa ukusebenza okuvamile kwe-valve ngaphansi kwezimo zokusebenza ezisezingeni eliphezulu.
