Stainless Steel Sanitary Manual Flange Lever Wafer Butterfly Valve
 
Stainless Steel Sanitary Manual Flange Lever Wafer Butterfly Valve is a manual hygienic Sanitary Valve butterfly valve Steel Valve with flange connection and lever operation. It is mainly installed on stainless steel hygienic pipelines in food, beverage, pharmaceutical and dairy industries, used for manual on-off and flow control of clean media. Types include 304/316L material versions, PTFE/EPDM seals, standard and high-pressure models, with full polished crevice-free design and compliance with DIN/ISO/3A standards for stable and hygienic operation.
 
Stainless Steel Sanitary Manual Flange Lever Wafer Butterfly Valve features full stainless steel construction, flange connection, mirror polishing, and crevice-free design, which is fundamentally different from ordinary industrial butterfly valves. It ensures no dead legs, easy cleaning, and high hygiene performance. Our product adopts precision forging, CNC machining, reliable eccentric sealing, and strict compliance with 3A/GMP standards, providing stronger durability, higher precision, and better corrosion resistance than similar products on the market.
