Lub valve disc ntawm lub cam khwb cia hlau nqa kos valve ua haujlwm tau txais. Feem ntau, lub conical valve disc yog nias tawm tsam lub rooj zaum hlau valve nyob nruab nrab ntawm qhov nkag thiab qhov hluav taws xob ntawm lub valve. Lub caij nplooj ntoos hlav tuaj yeem ntxiv rau lub valve disc rau preload. Thaum cov kua ntws mus rau pem hauv ntej, cov kua siab ua rau lub conical valve disc tawm ntawm lub rooj zaum valve, yog li qhib lub valve. Thaum cov kua dej ntws rov qab, lub valve disc rov qab mus rau lub rooj zaum valve vim nws qhov hnyav, lub caij nplooj ntoos hlav quab yuam (yog tias preload tau thov), thiab cov kua rov qab siab, ua rau lub valve kaw.
