Compact Float Valves with Plastic Reservoir for Food and Beverage
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).
