Q641TC-16/25/40 气动耐磨陶瓷密封球阀

陶瓷球阀、超硬密封面球阀，该产品球体、阀座及介质流过表面均采用陶瓷和超硬表面处理制造，特别适应金属球阀在使用的磨损比较苛刻的场合，开关扭矩小，密封可靠、使用寿命长等特点。

Hard sealed ceramic ball valve, the flat and medium flow through surface adopt pottery make, especially adapt to the occasion with more harsh wearing and tearing that the metal ball valve is being used, the switch torsion is small, characteristic of it is reliable to be sealed, having long performance etc.

硬密封陶瓷球阀和超硬陶瓷球阀是新开发的产品，改产品主要用于电力、石油、化工等管路系统上启闭装置。其中调节陶瓷球阀是电厂石灰石-石膏湿法脱硫工程中的重要产品，可提供等百分比特性的各种流道缺口，并按用户提出的流量系数进行选型和制造。

Hard sealed ceramic ball valve is the new product, it use on electricity, petroleum, chemical industry pipeline system open and close the device mainly. Adjustment ceramics ball valve is in the power plant limestone-gypsum aqueous method desulphurization project important product, may provide and so on. The minute bit each kind of flow channel gap, and the discharge coefficient which proposed according to the user, carries on the shaping and the manufacture.
