Discharging Rotary Valve For Powders

The ZAQ rotary discharging valve is a high-performance solution designed for reliable and efficient handling of powders and fine bulk materials in industrial processes. Engineered for demanding applications, this advanced discharging valve ensures maximum product capacity while maintaining extremely low leakage gas rates, making it ideal for high-efficiency material transfer.

Specifically developed for feeding bulk materials into pneumatic conveying systems, the ZAQ model performs reliably at pressures of up to 3.5 barg (51 psi). Its optimized sealing design minimizes air loss while maintaining consistent material flow, helping operators achieve stable conveying performance and improved energy efficiency.

Whether used in chemical, food, mineral, or plastics processing industries, the ZAQ rotary valve provides a robust and dependable solution for controlled powder discharge. With its focus on high throughput, reduced gas leakage, and compatibility with pressurized conveying systems, the ZAQ ensures smooth integration into modern bulk material handling systems while supporting continuous, high-capacity operation.

With optimal pocket sweeping, the ZXQ delivers consistent and reliable high-pressure powder conveying.

Designed For Optimal Results (ANPASSEN!)

The ZAQ rotary valve is designed for the efficient discharge of powders and bulk materials in pneumatic conveying systems. Based on the proven design of the ZXQ rotary valve, it offers the same robust construction and high sealing performance, optimized specifically for discharge applications. The valve features a reliable sealing system with double shaft seals and a labyrinth ring for effective gas purging, ensuring minimal leakage and consistent operation under pressure. Equipped with outboard bearings and a drop-out section, the ZAQ allows quick inspection and easy detection of seal wear without affecting the product area. Its 14-chamber open-end Q-Rotor is ideal for powder handling, providing uniform discharge and dependable performance in demanding environments.

Heated Housing for High-Temperature Operation

The ZAQ rotary valve is optionally available with a double-walled, heated housing for reliable operation in high-temperature applications.The valve can be heated with steam, water or circulating thermal oil up to 220 °C, making it suitable for product temperatures above 120 °C. The large heat transfer area enables fast pre-heating and uniform temperature distribution. Controlled heating also helps minimize leakage gas and ensures consistent performance when handling temperature-sensitive or challenging bulk materials.
