Butterfly Valves

LPC12 Sanitary Butterfly Valve

LPC12 Sanitary Butterfly Valve prioritizing absolute hygiene and streamlined maintenance, this valve utilizes a streamlined disc and crevice-free design to provide reliable flow control and isolation for high-purity, sensitive processing systems.

Product Description

Sanitary butterfly valves are engineered specifically for industries where preventing cross-contamination and ensuring rapid sterilization are paramount. Crafted from premium SUS304 or SUS316L stainless steel, the valve body and disc undergo precision electronic polishing to achieve a mirror-smooth surface (Ra ≤ 0.8μm). This flawless finish prevents product residue buildup and facilitates effortless cleaning.

Sanitary butterfly valve feature models fully encapsulated, FDA-compliant seat rings (such as EPDM, Silicone, or PTFE) that eliminate internal crevices and dead pockets. The valve operates with a streamlined, full-bore disc that aligns perfectly with the fluid flow, minimizing pressure drop and turbulence. Connected via Tri-Clamp, butt-weld, or threaded fittings, these valves integrate seamlessly into sterile pipelines and are fully compatible with automated CIP (Clean-In-Place) and SIP (Steam-In-Place) protocols.

Key Features

Streamlined, Crevice-Free Flow Path: The full-bore disc and polished internals eliminate dead legs, preventing bacterial growth and product stagnation.
Hygienic Encapsulated Seats: Fully encapsulated EPDM, Silicone, or PTFE seat rings prevent media entrapment and meet FDA, 3A, and EHEDG standards.
Rapid Disassembly: Tri-Clamp and multi-piece body designs allow for quick, tool-light removal for in-line inspection, cleaning, and seal replacement.
Sterilization Ready: Constructed to withstand high-temperature steam and aggressive cleaning chemicals during CIP/SIP cycles.
Low Pressure Drop: Aerodynamic disc profile ensures unobstructed flow, minimizing energy consumption and turbulence.
Compact & Lightweight: Space-saving design reduces structural load on piping racks and skids.
Automation Ready: ISO 5211 top flange supports direct mounting of sanitary pneumatic or electric actuators for automated process control.

Typical Applications

Data Center Liquid Cooling: Flow isolation and routing in cold-plate and immersion cooling systems requiring zero-particle, leak-free fluid control.
Food & Beverage: Dairy, juice, brewing, and syrup processing where fast CIP cleaning is required.
Biopharmaceutical: Purified water (PW), WFI distribution, and bioreactor feed lines.
Cosmetics & Personal Care: Transfer of high-purity emulsions, lotions, and creams.
Fine Chemicals: Handling ultra-pure solvents and corrosive media requiring zero metallic contamination.
