Sanitary stainless steel pressureless round manway

The manhole cover operates by forming a tight seal over manhole openings via its weighted, precision-engineered structure. Its heavy design and often interlocking or bolted mechanism resists displacement from traffic, pressure, or external forces. Sealing gaskets (where fitted) enhance leakproofing, preventing fluid leakage or debris entry. It is removable—lifted via built-in handles or tools—allowing access to underground pipelines or infrastructure while maintaining safety and structural integrity when closed.

Pneumatic Actuation – Provides fast, automated operation for precise flow control, reducing manual intervention and improving process efficiency.

Split Rotary Disc Design – Ensures smooth, stable flow modulation with minimal pressure drop and accurate control.

Stainless Steel Construction – Durable and corrosion-resistant, suitable for hygienic and high-purity applications.

Leak-Free Sealing – Precision-engineered seats ensure reliable shutoff and maintain sanitary integrity.

Sanitary Surface Finish – Smooth, crevice-free interior surfaces support cleaning-in-place (CIP) and minimize contamination risks.

Compact and Versatile – Space-saving design allows easy installation in pipelines and integration with automated systems

The Stainless Steel Sanitary Pneumatic Split Rotary Butterfly Valve is widely used in industries requiring precise, automated, and hygienic flow control. Typical applications include beverage production for controlled liquid distribution, pharmaceutical manufacturing for sterile fluid handling, biotechnology for media transfer, and food processing where contamination-free, accurate flow regulation is essential
