STAINLESS STEEL Sanitary Wafer-Type Concentric Rubber Seat Butterfly Valve

The stainless steel butterfly valve operates by rotating a disc mounted on a central shaft inside the valve body. When the disc rotates parallel to the flow direction, the valve opens, allowing gas or liquid to pass with minimal resistance. When the disc rotates perpendicular to the flow, it presses firmly against the vacuum-rated seat, creating a tight, leak-proof seal suitable for vacuum conditions. The clamp-style body enables easy installation and removal between flanges without disturbing the pipeline. Its design ensures stable operation, precise flow control, and reliable sealing, making it ideal for sanitary, pharmaceutical, and industrial vacuum systems.

Valve parts

• Constructed from 316L stainless steel, providing excellent corrosion resistance, mechanical strength, and long-term durability for industrial and chemical applications.
• Lug-type body allows secure flange installation, enabling easy maintenance and partial pipeline disassembly without affecting the entire system.
• Gearbox operation amplifies manual torque, making it easier to operate large-diameter valves with minimal effort.
• Visual position indicator provides clear feedback on valve status, helping operators quickly confirm open or closed positions.
• The disc and seat design ensures reliable sealing, low leakage, and stable flow control under varying pressure and temperature conditions.
  

Sanitary Butterfly valve widely use in low and medium viscosity liquid for food and beverage, beer, dairy, pharmaceutical etc with high precision and purity requirements industries.
