PDS 高頻球閥主要由球和閥座組成，在固體粉料系統中，它們時(shí)刻經(jīng)受著(zhù)因開(kāi)關(guān)而帶來(lái)的摩擦損傷。高頻球閥的核心技術(shù)就是確保閥球，閥座密封面涂層在長(cháng)時(shí)間高頻運行中保持良限的耐磨性和非常穩定的摩擦系數。高頻閥采用復合涂層，由基體、硬質(zhì)、合金層和潤滑層組成，同時(shí)具有良好的高溫和低溫機械性能。我公司的 PDS 高頻球閥在線(xiàn)使用 12 個(gè)月后，開(kāi)關(guān)超過(guò) 100 萬(wàn)次后，密封面依然光潔無(wú)泄漏。

PDS high-frequency ball valves are mainly composed of balls and seats, and are constantly subjected to friction damage caused by switches in the solid powder systems. The core technology of high-frequency ball valves is to ensure that the ball, seat sealing surface coating layer maintains good wear resistance and a very stable friction coeffi cient during the long and 
high-frequency operation. The high-frequency valve adopts a composite coating, consisting of a matrix, a hard, alloy layer and a lubricating layer, which have good high-temperature and low-temperature mechanical properties. After 12 months of online use of our PDS high-frequency ball valves and after more than 1 million times of opening and closing, the sealing surface still remains smooth and leak-free.
