Square mouth flange connection DN200 stainless steel rotary feeder valve

The 200x200 Square Inlet/Outlet Rotary Valve is a robust and essential component designed for precise feeding, discharging, and isolation of free-flowing bulk solids in demanding industrial processes. Its defining feature is the 200mm x 200mm (8" x 8") square flanged inlet and outlet, offering a perfect match for square ducting or spouting commonly found in pneumatic conveying, dust collection, and gravity feed systems. This design minimizes material hang-up and bridging compared to circular-to-square transitions, promoting smoother, more efficient material flow.

Constructed typically from durable cast iron, carbon steel, or stainless steel, the valve houses a rotor with multiple vanes (usually 6-10) rotating within a precisely machined housing. The close tolerance between the rotor tips and the housing, combined with high-quality lip seals or elastomeric end seals, ensures effective airlock performance. This is crucial for maintaining system pressure differentials in pneumatic conveying or preventing air ingress in vacuum systems, enhancing overall efficiency and control.

Key advantages of this specific 200x200 valve include:

Optimized Flow: The square ports align seamlessly with common system ductwork, reducing turbulence and product degradation.

Effective Airlock: Maintains pressure differentials critical for pneumatic conveying efficiency.

Volumetric Control: Provides reliable, consistent metering of bulk materials at adjustable rates.

Robust Construction: Built to withstand abrasive materials and continuous operation in harsh environments.

Versatility: Suitable for a wide range of applications including cement, plastics, grains, minerals, chemicals, and food processing (subject to material compatibility).

This valve excels in duties such as feeding material into pressurized or vacuum conveying lines, discharging from hoppers or silos, acting as an airlock in dust collectors, and providing controlled batch dosing. Its 200x200mm square interface makes it an ideal solution where integration with existing square ducting is paramount, ensuring reliable, low-maintenance, and leak-resistant handling of bulk solids across numerous industries.
