1″ Hudson Self‑Contained Float Valve – Automatic Tank Fill Valve

This 1″ Hudson Self‑Contained Float Valve is engineered for reliable liquid level control in buffer tanks, livestock troughs, irrigation systems, and soft‑wash setups. Featuring a compact, lever‑free design, it uses fluid pressure to regulate filling—no external float mechanisms needed.

Includes:

• One float valve with 1″ female NPT inlet connection

• Glass‑filled nylon body and ABS internal components for chemical and freeze resistance

• Stainless steel and silicone internals ensure durability and long-term performance

• Anti‑siphon design prevents backflow and contamination

Performance Specifications:

• Connection: 1″ FNPT inlet, 1″ FNPT outlet

• Flow capability: Approximately 80% of incoming flow, ideal for high‑volume refill situations

• Operating pressure range: 4 – 100 PSI, with positive shut‑off beyond typical buffer tank pressures

• Maximum temperature: up to 175 °F (approx. 90 °C) depending on seal option

• Dimensions: roughly 5″ height × 3.75″ diameter

• Weight: approximately 2 lb

Key Benefits:

• No float arm or lever eliminates a common failure point—ideal for freeze-prone or high-usage settings

• Anti-siphon design meets safety standards by preventing backflow contamination

• High-flow capacity and automatic shutoff maintain consistent water levels without overflow

• Durable materials resist UV, rust, and abrasive chemicals

• Compact form factor allows discreet installation inside tanks or enclosures
