1" Hudson Automatic Fill / Float Valve
The unique patented design of the Hudson Valve uses fluid pressure, as opposed to a lever arm and ball, as the force to close the valve. This compact, self-contained design greatly enhances the valve's reliability. The valve body is made of durable glass-filled nylon 6/6. Internal parts are of ABS plastic, silicone, and stainless steel. When properly installed, the valve will meet anti-siphon requirements.
