1/2″ Hudson Fill Valve Gravity / Pressurized Flow

Product details

1/2" Hudson Fill Valve Gravity / Pressurized Flow is an automatic fluid-control valve for maintaining tank or container levels using either gravity-fed or pressurized water sources. Designed for applications where you want a reliable, hands-free way to keep a reservoir topped off, it helps regulate incoming flow based on the fluid level—closing when the level rises and allowing refill when the level drops. This makes it a practical choice for aquarium top-offs and other water-management setups where consistent level control is important.
