Product Overview	The Pig Automatic Water Level Controller is designed to maintain a constant drinking water level in pig troughs and containers without requiring electronic sensors. It is especially suitable for newly weaned piglets, farrowing pens, sow housing and other commercial pig production areas where animals benefit from continuous access to a visible water surface. Unlike a conventional float valve installed directly inside the trough, a diaphragm-type water level controller can be positioned above the drinking surface and connected by a vertical pipe. This arrangement helps keep the control mechanism away from feed contamination and simplifies trough cleaning. The controller can be integrated into livestock equipment packages for pig farm construction and steel structure building projects. Pipe length, installation arrangement and water supply configuration can be selected according to project requirements.
Key Features	Automatically maintains a stable water level in pig drinking troughs. Vacuum-operated diaphragm design does not require electrical sensors. Especially suitable for newly weaned piglets and farrowing pens. Provides pigs with direct access to an open water surface. Controller body can be installed above the trough for easier cleaning. Integrated shut-off mechanism allows individual water points to be closed. Double-wall diaphragm design supports reliable repeated operation. Suitable for horizontal water pipe installation. Applicable to commercial pig farms, breeding units and livestock engineering projects.
Structural Components	Typical components may include: Water level controller body Flexible diaphragm assembly Integrated manual shut-off mechanism Water inlet and outlet connections Vertical stainless steel or project-specific pipe Pipe connector and sealing components Optional tilting drinking trough Optional wall mounting hardware Final configuration depends on the selected model and pig farm layout.
Working Principle	The controller uses vacuum pressure acting on a flexible diaphragm to regulate water flow. When the water level in the trough falls, the vacuum condition changes and the diaphragm allows fresh water to enter through the supply pipe. As the trough fills and reaches the designed water level, the pressure condition inside the system changes again and the diaphragm closes the water inlet. This maintains a relatively constant drinking water surface without a conventional float mechanism inside the trough. The controller also includes an individual shut-off function, allowing a specific drinking point to be isolated during cleaning or maintenance.

Installation & Maintenance	Install the controller on a horizontal water supply pipe and position the valve body above the trough. The vertical pipe should extend downward to the required water level according to the drinking trough design. For stable operation, the water supply should provide sufficient capacity and consistent pressure. A pressure reducer can be installed when necessary. Clean water or suitable filtration is recommended to reduce the risk of internal blockage. All inlet and outlet connections should be carefully sealed to prevent unwanted air leakage, which can affect vacuum operation. After installation, fill the system and confirm that the controller opens and closes correctly at the selected water level. Routine maintenance includes cleaning the trough, checking water flow, inspecting pipe seals and examining the diaphragm. A serviceable diaphragm design allows the membrane to be cleaned or replaced when required.
Project Cases	Pig water level controllers are suitable for centralized drinking systems in commercial breeding and finishing farms. Multiple controllers can be installed along water supply pipelines to maintain individual drinking troughs in farrowing, nursery, gestation and finishing sections. For new pig farm construction projects, the controllers can be planned together with main water pipes, pressure regulators, filters, medicators and drinking troughs to create a complete livestock water supply system. Installation quantity, pipe routing and mounting height can be configured according to house layout, animal group size and farm management requirements.
Product FAQ	Q: How does the water level controller maintain a constant water level? A: It uses vacuum pressure acting on a diaphragm to automatically open or close the water supply as the trough water level changes. Q: Is electricity required? A: No. The standard diaphragm-operated configuration works mechanically without electronic level sensors. Q: Is it suitable for newly weaned piglets? A: Yes. A visible water surface can help newly weaned piglets learn to drink more easily. Q: Can it be used for sows? A: Yes. It is suitable for farrowing and sow trough applications when correctly sized and installed. Q: What water pressure is recommended? A: The reference system is specified for approximately 0.5-3 bar. Stable pressure and adequate pipeline capacity are important for reliable operation. Q: Can the valve be closed individually? A: Yes. The reference design includes an integrated shut-off function for individual drinking points. Q: Can the installation height be customized? A: Yes. Pipe length and mounting arrangement can be adapted according to trough height and project requirements.
