Product Name	Anti-Siphon Metal Trough Float Valve
Product Image
Product Overview	The Anti-Siphon Metal Trough Float Valve is designed for automatic water-level management in livestock troughs, stock tanks, barrels and similar watering containers. A durable aluminum housing protects the valve mechanism, while the float-operated design automatically opens the water supply as the level falls and closes it when the preset level is restored. The integrated anti-siphon configuration helps reduce the risk of reverse water movement toward the supply line, making the valve suitable for commercial livestock watering systems where water hygiene, dependable operation and simple installation are important.
Key Features	Automatic float-operated water-level control reduces manual trough filling. Anti-siphon design provides additional protection against back-siphoning. Durable aluminum housing for demanding livestock and agricultural environments. Nylon orifice provides reliable water-flow control with good corrosion resistance. Adjustable expansion brackets simplify mounting on different trough and tank rims. Standard hose connection allows convenient integration with farm water-supply systems. Suitable for centralized watering systems in commercial pig farms and other livestock facilities. Compact mechanical construction requires no electrical power or control unit.
Structural Components	Aluminum Housing: Protects the internal float-valve mechanism against impact and routine farm use. Float Mechanism: Detects changes in trough water level and mechanically operates the inlet valve. Nylon Orifice: Controls incoming water flow and provides resistance to corrosion and mineral exposure. Anti-Siphon Assembly: Helps interrupt undesirable reverse siphoning toward the water-supply line. Expansion Brackets: Secure the assembly to the rim of compatible livestock troughs and stock tanks. Water Inlet Connection: Connects the valve to a standard farm hose or compatible pipe adapter.
Working Principle	When livestock consume water and the trough level drops, the float moves downward and mechanically opens the inlet valve. Fresh water enters the trough until the float rises to the preset level, at which point the valve closes automatically. The anti-siphon section is incorporated into the inlet arrangement to help reduce back-siphoning from the trough toward the upstream water line. Final installation should comply with local plumbing, water-quality and livestock-farm biosecurity requirements.

Applications	Commercial pig farms and swine production buildings Sow, nursery and finishing-house auxiliary watering systems Cattle and dairy farm stock tanks Sheep and goat watering troughs Horse and equine watering tanks Outdoor livestock yards and holding areas Farm water-storage barrels, pans and utility tanks Livestock equipment projects and complete farm water-supply installations
Customization Options	For livestock-equipment projects, connection and installation configurations can be selected according to the farm water system and trough structure. Available options may include compatible inlet adapters, mounting accessories, hose or pipe connection kits and project-specific packaging. Final configuration is customizable according to project requirements and local farm conditions.
Installation & Maintenance	Mount the valve firmly on the trough or tank rim using the supplied or compatible expansion brackets. Position the float so it can move freely without contacting the trough wall or other equipment. Flush the upstream water line before connection to reduce sediment entering the valve orifice. Connect the inlet to the compatible water-supply hose or pipe adapter and check all joints for leakage. Maintain supply pressure within the recommended operating range; use an upstream pressure regulator when required. Periodically inspect the float mechanism, inlet, orifice and mounting brackets for sediment, wear or looseness. Clean mineral deposits as required and protect or drain exposed water equipment where freezing conditions occur. Confirm local backflow-prevention requirements when integrating the valve into centralized potable or farm water systems.
Product FAQ	Q: What does the anti-siphon function do? A: It is designed to help reduce back-siphoning from the livestock trough toward the upstream water supply. Local plumbing regulations should still be checked for each project. Q: Does the valve require electricity? A: No. Water-level control is performed mechanically by the float and valve mechanism. Q: What water pressure is recommended? A: The reference operating range is approximately 20-50 psi. Where farm-line pressure exceeds this range, an appropriate upstream pressure regulator should be considered. Q: Can it be used in commercial pig farms? A: Yes. It can be installed on suitable troughs or auxiliary stock tanks in pig houses, service areas and livestock watering systems, provided the required flow capacity and mounting conditions are confirmed. Q: Can the connection be adapted to metric farm pipework? A: Compatible adapters and connection solutions can be supplied or selected according to project requirements. Q: Is regular maintenance required? A: Routine inspection and cleaning of the float mechanism, orifice, inlet connection and mounting hardware are recommended to maintain reliable water flow.
