The Sweetwater Float Valve is a durable, automatic water level control valve designed for livestock water troughs, storage tanks, reservoirs, and other low-pressure water systems. Manufactured for reliable operation, it maintains a consistent water level by automatically opening when the water level drops and closing once the desired level is reached.

Available in both mild steel and stainless-steel construction, the Sweetwater Float Valve is built to withstand demanding agricultural environments. The mild steel model is electroplated and powder-coated to provide excellent protection against corrosion and lime scale build-up, while the stainless-steel option offers enhanced corrosion resistance for harsh or highly corrosive conditions.

Designed for high-flow, low-pressure applications, these float valves are ideal for:

• Livestock drinking troughs

• Water storage tanks

• Reservoirs

• Agricultural water systems

• Gravity-fed water installations

The robust mechanical design ensures dependable performance with minimal maintenance, helping to prevent water wastage while ensuring a continuous supply of fresh water for livestock and irrigation applications.
