针对极端恶劣的工作条件对标准球阀进行了改进,以便它们现在能适用于高达370℃的高温和诸如焦油沙那样的磨研介质的工作条件。使用了耐化学腐蚀的特种钢和硬质材料涂层。阀内腔受热载体油的冲刷,故不需要加热外套。
Standard ball valves have been modified for extremely harsh working conditions so that they are now suitable for high temperatures up to 370 ° C and operating conditions for grinding media such as tar sands. Corrosion-resistant special steel and hard-material coatings are used. Valve cavity by the heat carrier oil erosion, it does not need heating jacket.
