All-Brass Swine Drinking Nipple Valve

This is an All-Brass Swine Drinking Nipple Valve,  an automated livestock drinking fitting specifically designed for large-scale pig farms. Commonly referred to in the industry as a "duck-bill" pig water nipple, its main body is integrally forged from high-purity brass. It features a stainless steel plunger (poppet) and a stainless steel return spring, with a red dust-proof plug at the top. It is compatible with PVC and galvanized water supply piping systems commonly used in pig houses, and meets the drinking water needs of pigs at all growth stages - including piglets, growing-finishing pigs, and sows. It is a standard water-saving drinking equipment in modern pig farms.

◆ Durable and corrosion-resistant material: The valve body is made of solid brass, while the plunger (poppet) and return spring are constructed from 304 stainless steel, offering excellent resistance to the corrosive effects of acidic and alkaline manure and wastewater commonly found in pig farms. It is highly resistant to rust and cracking, with a service life far exceeding that of plastic or low-grade stainless steel alternatives.

◆ Outstanding water-saving performance: Compared with traditional open trough drinking systems, this nipple valve reduces water consumption by over 60%, significantly minimizing standing water and humidity in pig pens, thereby lowering the incidence of respiratory diseases and diarrhea.

◆ Extremely low failure rate: The internal structure is streamlined and simplified, with no complex components, making it highly resistant to clogging by feed particles or debris. It requires virtually zero routine maintenance.

◆ Ergonomic design suited to swine drinking behavior: The duck-bill curved wrap-around configuration conforms to the natural biting and sucking action of pigs' mouths. Water is delivered precisely into the oral cavity, minimizing spillage and reducing wetting of the pigs' bodies.

◆ Easy maintenance: The removable red dust-proof cap allows for quick access to clean internal scale buildup and feed residue, ensuring straightforward and convenient flushing and unclogging.

◆ Sealing performance: Equipped with multi-layered rubber O-rings, the valve ensures zero drip leakage under static conditions, with no weeping or seepage even during fluctuating water supply pressure.

◆ Temperature and corrosion resistance: The brass valve body operates reliably across a temperature range of -10°C to 60°C, and withstands corrosive exposure to urine, manure, and disinfectant solutions commonly used in pig houses, with no oxidation or weeping over prolonged service.

◆ Mechanical durability: The plunger is rated for over 100,000 actuation cycles without functional failure, while the return spring maintains consistent, snap-action responsiveness with no sticking or sluggishness.

This drinking nipple is designed for use in water supply systems across a broad range of swine housing facilities, including large-scale intensive pig operations, smallholder enclosures, piglet nursery units, sow farrowing stalls, and finishing grow-out pens.
