?密封性能良好，使工作環(huán)境中的空氣不能進(jìn)入內(nèi)部對(duì)于工作在高溫下的系統(tǒng)，密封性好的液壓閥可以承受很高的壓力，不會(huì)產(chǎn)生泄漏這意味著液壓閥可以承受更大的壓力(100MPa)工作溫度高(超過(guò)350)℃）液壓閥包括閥體和閥座、閥體和閥蓋、閥體連接器、密封件和連接環(huán)；閥體連接器為螺母或閥體緊固件；密封圈為聚四氟乙烯，機(jī)械強(qiáng)度高，耐熱、耐酸堿、耐腐蝕性好；耐高溫、耐低溫(-260℃);密封件不會(huì)老化或泄漏；耐高溫；低溫下延展性強(qiáng)，抗蠕變性強(qiáng)；密封面非常耐磨，抗沖擊強(qiáng)度和耐高溫性好。
閥體連接件由鋼或合金鋼制成；襯墊是良好的選擇；連接方式選擇通過(guò)螺栓連接；或在接頭中使用螺栓密封體來(lái)防止閥門(mén)在工作時(shí)泄漏液體或氣體等介質(zhì)（如油和水）在環(huán)境中壓力為1-2kpa時(shí)是無(wú)泄漏的；耐腐蝕性好；可承受高溫和極端溫度；在低溫下仍然能正常工作；密封件具有良好的密封性能，使連接件之間不會(huì)發(fā)生泄漏，因此易于維護(hù)和維修。
