?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；連接方式選擇通過螺栓連接；或在接頭中使用螺栓密封體來防止閥門在工作時(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，使連接件之間不會發(fā)生泄漏，因此易于維護(hù)和維修。
主要特點(diǎn)：產(chǎn)品密封性好、耐低溫、使用壽命長等特點(diǎn)為國內(nèi)外高壓設(shè)備提供了可靠產(chǎn)品和服務(wù)！1)產(chǎn)品：液壓調(diào)節(jié)器和控制閥門等產(chǎn)品;2)有各種結(jié)構(gòu)、密封和閥配件;3)具有自動切換功能和自我保護(hù)功能;4)有連接件可確保閥門或換向器安裝固定平穩(wěn)和連續(xù)地工作；具有自動檢測故障功能；可進(jìn)行維護(hù)保養(yǎng)和更換新部件；具有故障報(bào)告卡及操作手冊；具有記錄設(shè)備數(shù)據(jù)接口功能；各種技術(shù)文件；并具有相關(guān)文件打印功能；在不同介質(zhì)中有不同顏色說明等其他性質(zhì)（如標(biāo)記);具有標(biāo)記；通過電子信號和控制系統(tǒng)信息查詢功能；具有自檢功能以及安裝調(diào)試功能；還具有故障診斷功能。
