1″ Hudson Fill Valve Gravity / Pressurized Flow

Product details

1" Hudson Fill Valve Gravity / Pressurized Flow is an automatic fill valve designed to help maintain fluid levels in tanks and plumbing applications. It uses float and diaphragm action to start and stop incoming flow as the liquid level rises and falls, making it useful for replacing many ball-float styles. In aquarium and pond-type setups, it can serve as a practical top-off or supply-control valve for systems where you want reliable, consistent filling without a manually operated lever.

Features:

• 1" universal Hudson valve for fluid level control in compatible applications
• Automatic operation uses rising float action and diaphragm expansion to close the chamber as the level increases
• Designed with durable internal materials including ABS plastic, EPDM rubber, and stainless steel
• Built to be resistant to freezing, helping prevent damage in cold conditions
• Anti-siphon design helps reduce backflow risk when used as intended
• Includes thread and compact form factor for straightforward installation in seconds
• No exterior moving parts and no lever arm for a cleaner, less snag-prone setup
• Resistant to rust and suitable for both gravity and pressurized use within listed limits
