3" Sanitary 316L Stainless Steel One Way Check Valve

Sanitary check valve

Designed for larger-scale home projects and light commercial use, this valve ensures liquids flow only forward—no back-splashing, no residue traps, and no compromise on hygiene. Perfect for 10-gallon+ brew setups, small-batch sauce lines, or lab-grade fluid systems, it’s the heavy-duty check valve you’ve been waiting for.

Built for Harsh, Hygienic Environments

Ealge’s valve is forged from 316L stainless steel (the “workhorse” of food-grade metals), resisting corrosion from acids (think citrus in jams, hops in beer), sanitizers, and even saltwater. Unlike cheaper 304 steel or plastic, it won’t rust or leach chemicals—keeping your products pure and your process safe.

Smooth, Crevice-Free Design

Traditional check valves trap gunk in tiny gaps, but Ealge’s electropolished interior (Ra ≤12 µin) is so smooth, residue slides right off. Disassemble with a single wrench, rinse with hot water, and you’re ready for the next batch—no scrubbing, no tools, no hidden bacteria.

Industrial-Grade Performance, Home-Scale Simplicity

At 3" size, this valve handles higher flow rates (up to 50 GPM) than smaller check valves, making it ideal for:

Homebrew: 10-20 gallon fermenters to bottling lines (no beer backflow).

Artisan Food: Bulk sauce or yogurt dispensing (no cross-contamination between batches).

DIY Labs: Essential oil distillers or lab-grade fluid transfer (no steam back-splashing).
