Product Name	Metal Trough Float Valve with Expansion Brackets

Product Overview	The Metal Trough Float Valve with Expansion Brackets is a mechanical automatic water-level control valve designed for livestock drinking troughs, stock tanks and similar water containers. A durable metal housing protects the internal float mechanism, while adjustable expansion brackets allow secure mounting on standard and wide trough rims. The valve automatically replenishes water as livestock drink and shuts off the inlet when the preset level is restored, making it suitable for commercial pig farms, cattle farms, goat-farming-equipment/" target="_blank" class="keylink">sheep and goat facilities, and general livestock watering systems.
Key Features	Automatic mechanical control maintains the required trough water level without electricity. Durable aluminum housing protects the float and valve components in demanding livestock environments. Expansion bracket system accommodates a wider range of trough and tank rim configurations. Suitable for both plastic and metal livestock water tanks and troughs. High water delivery capacity supports livestock drinking-water replenishment. Simple mechanical construction facilitates installation, inspection and routine maintenance. Suitable for new livestock-house construction, farm renovation and replacement water-system projects.
Structural Components	Metal Valve Housing: Provides mechanical protection and structural strength. Float Assembly: Responds directly to changing water levels inside the trough. Valve Seat: Controls inlet opening and shut-off as the float moves. Orifice Insert: Regulates water entry through the valve assembly. Expansion Brackets: C-shaped and extension mounting components support installation on different rim widths. Thumb Screws and Fasteners: Allow secure positioning and convenient installation. Water Inlet: Compatible with standard water-supply connections.
Working Principle	The internal float rises and falls with the water level inside the trough. When livestock consume water and the level drops, the float lowers and mechanically opens the inlet valve. Water flows into the trough until the desired level is restored. As the float rises, the valve seat progressively closes the inlet and stops the water supply. This float-operated principle provides continuous automatic water replenishment without electrical sensors, controllers or external power.

Applications	Pig drinking troughs and stock tanks Sow gestation and breeding facilities Pig finishing and wean-to-finish houses Cattle and dairy farm drinking troughs Sheep and goat watering systems Plastic and galvanized livestock water tanks Commercial livestock farm construction and water-system renovation projects
Customization Options	Water inlet connection according to project requirements Mounting arrangement for different trough and tank structures Water supply pipe and accessories available upon request Valve quantity and system layout according to livestock-house capacity Complete drinking-water system configuration designed according to farm requirements
Installation & Maintenance	Position the valve over the trough or tank rim and select the appropriate expansion-bracket configuration. Tighten the mounting brackets evenly to secure the valve without damaging the trough rim. Connect the water supply and verify that all washers and threaded connections are properly sealed. Confirm that the float moves freely before opening the water supply. Adjust the float position where applicable to establish the required water level. Periodically inspect the valve seat, float, inlet orifice and mounting hardware for sediment, wear or looseness. Use upstream filtration where water contains sand, rust or suspended particles.
Project Cases	Suitable for commercial livestock projects requiring automatic water-level control in existing or newly installed drinking troughs. Valve quantity, trough configuration, supply-pipe layout and mounting details can be matched to pig house, cattle barn or other livestock facility requirements.
Product FAQ	Does the float valve require electricity? No. Water level is controlled mechanically by the internal float assembly. What is the purpose of the expansion brackets? The bracket system allows the valve to be securely mounted on a wider range of tank and trough rim sizes than a basic fixed mounting arrangement. Can it be installed on both metal and plastic troughs? Yes. The valve is suitable for many plastic and metal livestock tanks and troughs when the rim dimensions and mounting structure are compatible. Can it be used in commercial pig farms? Yes. It can be used for automatic water replenishment in pig troughs as well as cattle, sheep and goat watering systems. Can the valve connection or installation configuration be customized? Yes. Connection arrangements, mounting solutions and associated water-line components can be supplied according to project requirements.
