Sanitary manual butterfly valves are essential components in hygienic processing systems, designed to regulate fluid flow with reliability and efficiency. These valves feature a compact disc-operated mechanism that enables quick shut-off and precise flow adjustment, making them ideal for industries where cleanliness and operational speed are paramount.
vailable in sizes from DN10 to DN300, these valves support multiple end connections (clamp, weld, thread,flange) and handle options. Lever handles provide rapid operation for frequent adjustments, while gear operators deliver enhanced torque control for high-pressure applications.
Constructed from 304/316L stainless steel with surfaces (Ra ≤0.8μm), these valves prevent bacterial growth and meet 3-A, FDA standards. Their crevice-free design and CIP/SIP compatibility ensure effortless cleaning, while EPDM/FKM/PTFE seals maintain integrity across temperatures from -20°C to 130°C.
Widely used in biopharmaceuticals, food and beverage, and dairy processing, these valves ensure zero contamination risk during critical operations. Their full-bore design minimizes pressure drop, and quick-disassembly features simplify maintenance, reducing downtime in continuous production environments.
1. Zero Dead Legs: Smooth internal surfaces prevent material accumulation
2. Quick Operation: 90° rotation enables full open/close functionality
3. Long Service Life: Robust construction withstands frequent cycling
4. Adaptable Sealing: Multiple elastomer options for diverse media compatibility
By combining sanitary compliance with mechanical reliability, manual butterfly valves deliver optimal performance in demanding hygienic processes while minimizing total cost of ownership through reduced maintenance and extended service intervals.
