Coperion Offers ZXQ DuroProtect Wear Resistant Rotary Valve

The Coperion ZXQ DuroProtect blow-through rotary valve is specially designed for abrasive applications. It is used for conveying products in powder form (smaller than 1 mm). The blow-through configuration enhances rotor pocket cleanout while conveying and allows installation in tight quarters. 

The ZXQ DuroProtect includes patented blow-through channel for optimal pocket sweeping and offers pressure differentials up to 3.5 bar(g) [51 psi(g)] and temperatures up to 100°C [212°F] standard.

The highest level of abrasion resistance consists of a DuroCera ceramic lined bore and blow-through channel with DuroCarb tungsten carbide coated rotor tips. The DuroProtect design is optimized for product properties (in particular abrasiveness) and operating conditions (particularly pressure difference).

The design effectively incorporates erosive wear protection. High wear resistance ensures long-term low leakage gas rates and lasting service life.
