Product Name	Diaphragm Livestock Water Level Controller
Product Image
Product Overview	The Diaphragm Livestock Water Level Controller is designed to maintain a stable water level in livestock troughs and drinking containers. Unlike a conventional float valve positioned directly inside the trough, the main valve body can be installed above the water surface, helping simplify trough cleaning and reduce direct contamination around the control mechanism. The system is especially suitable for newly weaned piglets and farrowing pens, where animals benefit from continuous access to an open water surface. It can also be integrated into commercial pig farm drinking systems, livestock equipment packages and new pig farm construction projects. The controller uses a vacuum-operated diaphragm principle to stop and restart water flow automatically as the water level changes. :contentReference[oaicite:1]{index=1}
Key Features	Maintains a stable water level in livestock troughs and drinking containers. Vacuum-operated diaphragm design provides automatic water flow control. Especially suitable for newly weaned piglets and farrowing pens. Valve body can be installed above the water surface for easier trough cleaning. Integrated shut-off mechanism allows individual valve isolation. Suitable for installation on horizontal water pipes. Manual closing function supports convenient maintenance and service. Double-wall diaphragm design improves service life compared with simpler membrane structures. Suitable for commercial pig farms, livestock equipment installations and steel structure building projects. :contentReference[oaicite:2]{index=2}
Structural Components	A typical diaphragm water level controller may include: Water level control valve body Double-wall rubber diaphragm Vacuum sensing chamber Manual shut-off mechanism Water inlet and outlet connections Pipe connection fittings Optional stainless steel connection pipe Optional trough and wall mounting accessories Replaceable diaphragm and sealing components Selected configurations are available with a 120 cm stainless steel pipe or as a valve-only version. :contentReference[oaicite:3]{index=3}
Working Principle	The controller operates through a vacuum acting on a flexible rubber diaphragm. As the trough reaches the required water level, the vacuum condition causes the diaphragm to close the water passage and stop further filling. When animals drink and the water level falls, the vacuum condition changes and the diaphragm allows water to enter again. This cycle automatically maintains the selected water level without a conventional float mechanism inside the trough. Because the main valve body can be installed approximately above the drinking surface, the trough area remains more accessible for routine cleaning. :contentReference[oaicite:4]{index=4}

Installation & Maintenance	Install the controller on a horizontal water pipeline and ensure that the pipeline has sufficient water capacity for the required livestock drinking demand. Clean water is recommended. Where sediment or suspended material is present, an upstream filter should be installed to help prevent blockage. The reference manufacturer recommends stable water pressure and the use of a pressure reducer where necessary. :contentReference[oaicite:6]{index=6} Pipe inlet and outlet connections should be sealed carefully to prevent false air from interfering with the vacuum operating principle. The diaphragm can be accessed for cleaning or replacement through the bayonet-style closure. Routine inspection should include the membrane, sealing points, pipeline connections and water level response. :contentReference[oaicite:7]{index=7}
Project Cases	Diaphragm water level controllers are particularly suitable for pig nursery and farrowing projects where open drinking surfaces are preferred for young piglets or sows. In new pig farm construction projects, multiple controllers can be installed along horizontal water pipelines to serve individual troughs or pen groups. Water pressure reduction, filtration, drinking troughs and pipeline accessories can be planned as part of a complete livestock equipment package. For sow applications, the reference manufacturer notes that a shallow trough water level can help reduce the risk of feed entering the water pipe. :contentReference[oaicite:8]{index=8}
Product FAQ	Q: How is this different from a conventional float valve? A: It uses vacuum and a rubber diaphragm to control water flow, allowing the main valve body to be positioned away from the trough water surface. Q: Is it suitable for newly weaned piglets? A: Yes. The reference system is specifically recommended for newly weaned piglets that benefit from access to an open water surface. :contentReference[oaicite:9]{index=9} Q: Can it be used in farrowing pens? A: Yes. It can maintain continuous water availability in sow and farrowing troughs. Q: What water pressure does the reference system require? A: The reference configurations are rated for 0.5-3 bar, while the manufacturer recommends stable supply pressure and pressure reduction where required. :contentReference[oaicite:10]{index=10} Q: Is the diaphragm replaceable? A: Yes. Replacement diaphragms are available, and the membrane can be accessed through the bayonet-style closure. :contentReference[oaicite:11]{index=11} Q: Can the system be customized for a complete pig farm project? A: Yes. Valve quantity, pipe configuration, trough arrangement, filtration and pressure-control components can be selected according to project requirements.
