Product Name	Float-Free Membrane Water Level Valve
Product Image
Product Overview	The Float-Free Membrane Water Level Valve is designed to automatically maintain a stable drinking-water level in livestock troughs and tanks without a conventional float, electronic sensor or electrical power. Its compact membrane-operated structure is well suited to commercial pig farms, including farrowing, gestation, nursery and finishing facilities. The valve can be integrated with stainless steel or compatible livestock water pipe assemblies, providing a practical solution for new pig house construction, drinking-system upgrades and complete farm equipment projects.
Key Features	Float-free membrane control eliminates bulky mechanical float assemblies. Automatically maintains a consistent water level in drinking troughs or tanks. No electricity or electronic water-level sensor is required. Compact design suits confined pig pens and livestock housing installations. Tool-friendly housing allows convenient access to the internal membrane for inspection and servicing. Rotatable regulating connection simplifies alignment during installation. Suitable for centralized drinking-water systems in commercial livestock farms.
Structural Components	Valve Housing: Compact polymer body designed for livestock-house environments. Flexible Membrane: Main sensing and water-control element inside the valve head. Housing Clips: Quick-release clips provide convenient access during servicing. Regulating Port: Integrated adjustment section for setting and controlling valve operation. Pipe Connection: Designed for connection with compatible livestock water supply pipe assemblies. Sealing Components: Internal seals help provide stable shut-off and reliable water control.
Working Principle	The valve uses a flexible membrane to respond automatically to changes in trough water level. When animals consume water and the level drops, the membrane-controlled mechanism opens the water supply. As the preset water level is restored, the membrane actuates the valve toward the closed position. This principle provides automatic water-level regulation without an external float arm, electrical controller or level sensor, reducing mechanical complexity in the drinking system.

Applications	Commercial pig drinking troughs and water tanks Sow gestation and breeding houses Farrowing houses and sow drinking systems Piglet nursery and weaner facilities Finishing and wean-to-finish pig houses Livestock farm renovation and water-system upgrades Integrated pig farm construction and livestock equipment projects
Customization Options	Water pipe length and installation configuration Stainless steel pipe and mounting accessories Connection interfaces according to project requirements Valve and trough combinations for different pig production stages Complete drinking-water system packages available upon request
Installation & Maintenance	Install the valve and supply pipe securely above or adjacent to the livestock trough according to the required water level. Use clean water and an upstream filtration system where water quality contains sediment or suspended particles. Flush water lines before commissioning a new installation. Inspect the membrane and sealing surfaces periodically for deposits, wear or damage. Clean the supply pipe regularly to support good drinking-water hygiene. Confirm pressure, pipe configuration and installation height before bulk project installation.
Project Cases	Suitable for new-build and renovation projects involving commercial pig houses, steel structure livestock buildings, sow farms, nursery units and finishing barns. Valve quantity, pipe layout and water supply configuration can be designed according to farm capacity and project requirements.
