金屬硬密封球閥具有耐高溫、耐高壓、耐強腐蝕性及耐磨損的特點，適用于工況比較惡劣的情況；工作 狀態(tài)下，其所需轉(zhuǎn)矩小，操作方便，密封安全可靠，使用壽命長，壓力損失比較小。由于硬密封球閥具有 以上優(yōu)點，其應(yīng)用日益廣泛，越來越受用戶及閥門生產(chǎn)廠家重視。應(yīng)用行業(yè)：煤化工、光伏產(chǎn)業(yè)、石油化 工、造紙、空分等。

The metal rigid-sealed ball valve has the characteristics of high temperature resistance, high pressure resistance, strong corrosion resistance and wear resistance, and is suitable for harsh working conditions. Under the working conditions, they require low torque, are easy to operate, have reliable sealing, a long service life, and relatively small pressure loss. Due to the above advantages, the application of rigid-sealed ball valves is becoming increasingly widespread, which catches more and more attention from users and valve manufacturers. Application industries: coal chemical industry, photovoltaic industry, petrochemical industry, papermaking, air separation, etc.
