Product Description

Hygienic Hastelloy Buttefly Valves for Powder Powder Butterfly Valve Manual

A is designed for handling dry powders and granules in hygienic industries such as food, dairy, and pharmaceuticals. It features a smooth bore and low-friction disc, ensuring minimal powder buildup and easy flow. The valve is ideal for gravity-fed systems like hoppers or mixers, allowing precise on/off or throttling control. Its quick-disassembly structure enables fast cleaning, while the air-tight seal prevents product leakage and contamination. With Tri-Clamp or flange connections, it integrates seamlessly into sanitary processing lines.

Working principle
The stainless steel sanitary powder butterfly valve works by rotating a central disc within the valve body to control powder flow. When the disc is aligned with the flow, powder passes through freely. Rotating the disc perpendicularly blocks the flow. The low-friction surface minimizes sticking and residue buildup. An airtight seal ensures no leakage during operation. The valve is usually manually or pneumatically actuated for precise control. Its quick-release design allows easy cleaning without removing the entire assembly.

Product Description

 

Stainless steel sanitary valves are widely used in high-cleanliness industries and have the following significant feature:
1.Disc edge curvature prevents powder bridging
The specially contoured disc edge reduces dead zones and allows fine powders to pass without bridging, improving flow consistency and reducing clogging.

2.Non-stick polished sealing surface
Mirror-polished sealing zones minimize material adhesion, helping powders slide off the disc during closing for better cleanability and product integrity.

3.Offset shaft to reduce friction torque
The slightly offset shaft design lowers contact friction, which makes manual or pneumatic actuation smoother and more energy efficient.

4.Dust-tight seal with micro-groove ring fit
A custom compressed seal geometry fits tightly even under low-pressure powder loads, ensuring leak-free operation in vertical or slanted setups.

5.Tool-free clamp unlocking for fast inspection
The quick-release body clamp enables frequent maintenance or batch changeovers without tools, helping reduce downtime in cleanroom conditions.

6.Thicker disc core to resist granular abrasion
The disc includes a reinforced midsection that withstands abrasive solids, extending the valve's service life in powder handling lines.
