Hudson Anti-Siphon Float Valve

Hudson V Anti-Siphon Float Valve

The Hudson V Anti-Siphon Float Valve is a durable, automatic fluid level control valve designed to maintain consistent tank or trough levels while replacing traditional ball float valves. Built to be damage-proof and resilient in tough environments, it uses a float-actuated diaphragm system: as fluid rises, the float lifts and the diaphragm expands to shut off incoming flow; when fluid drops, the diaphragm escape opens to refill automatically. With internal components made from ABS plastic, EPDM rubber, and stainless steel, it delivers reliable performance and is resilient to freezing for dependable operation in changing conditions.
