Amarga fungsi ngundhakake unsur gangguan lan nyambungake, ngatur lan nyebarake, misahake lan nyampur media ing Valvpassage, permukaan, lan nganggo media, sing ndadekake kerusakan.

There are two reasons for the damage to the sealing surface: human damage and natural damage. Human damage is caused by factors such as poor design, manufacturing, material selection, improper installation, poor use, and maintenance. Kerusakan alami yaiku nyandhang lan nyuwek kahanan kerja normal lan disebabake dening karat lan erosi sing ora bisa dielingi ing permukaan.
Kualitas macan sing kurang apik: Iki utamane diwujudake kanthi cacat kayata retak, pori, lan inklusi ing permukaan panyegelan. This is caused by improper selection of welding and heat treatment standards, as well as poor operation during welding and heat treatment. The sealing surface's hardness is too high or too low due to improper material selection or improper heat treatment. Kekurangan sing ora rata lan resistensi karat sing kurang lemah utamane amarga nyebul logam ing ngisor ing permukaan sajrone proses welding, sing nyuda komposisi welding lumahing. Of course, design issues also exist in this regard.
katups miturut kahanan kerja, kanthi nggunakake katup sing ditutup minangka katup sing nggegirisi, nyebabake tekanan sing gedhe banget nalika ditutup kanthi cepet, utawa penutupan sing ora lengkap, nyebabake lumahing segel. Incorrect installation and poor maintenance lead to abnormal operation of the sealing surface, causing thekatup
Korosi kimia medium: medium sing ngubengi permukaan sealing sing ditanggepi karo permukaan panyegelan tanpa ngasilake lumahing sealing. Electrochemical corrosion, contact between the sealing surfaces, contact between the sealing surface and the closing body andkatupBadan, uga beda karo konsentrasi lan isi oksigen medium, kabeh ngasilake bedane potensial, nyebabake korosi electrochemical lan corroding permukaan sealing sisih pinggir.
Kerusakan lemes: Perselur sing dienggo kena gantian sulih sajrone panggunaan jangka panjang, nyebabake lemes lan nyebabake retak lan delaminasi. Rubber and plastic are prone to aging after long-term use, which leads to decreased performance. Saka analisis panyebab karusakan ing ndhuwur, bisa uga katon kanggo nambah kualitas lan layanan layanan sealing valve, bahan panyunting sing cocog, lan cara pangolahan kudu dipilih.
