Compact Float Valves for Food and Beverage

With 316 Stainless Steel Float

With Polypropylene Float

Smaller than other float valves, these are sized for containers with limited space. They meet NSF/ANSI Standard 169 for food-equipment components and have excellent corrosion resistance. The discharge outlet is unthreaded and releases contents into your tank.

Compact Float Valves with Plastic Reservoir for Food and Beverage

With Top Inlet

With Side Inlet

Commonly used in ice-making machines, these valves have floats that rest inside a clear plastic reservoir. They meet NSF/ANSI 169 standards for food equipment components. Polypropylene plastic floats are FDA compliant for direct food contact. The discharge outlet is unthreaded and releases contents into your tank. The drain holes are located on the bottom for connecting to soft tubing (not included).
