Chúng phù hợp cho các nhu cầu mua sắm kỹ thuật khác nhau như cấp nước gia đình, nồi hơi sưởi ấm và hệ thống phun nước chữa cháy, đồng thời hỗ trợ cả xử lý bán buôn số lượng lớn và xử lý tùy chỉnh.
1. It is made by forging HPb59 non-lead anti-zinc removal brass in one piece, with a dense material without sand holes. It is not prone to rust or the release of harmful substances when in continuous water flow, allowing for the safe use of drinking water pipelines.
2. The inner wall of the valve body undergoes precise polishing treatment, ensuring smooth water flow, lower resistance, and no problems such as water accumulation in the pipeline or excessive water pressure loss.
3. The surface of the valve body is treated with nickel plating for rust prevention. In complex environments such as damp manholes, high-temperature boilers, and damp fire protection pipelines, it can delay the formation of scale and metal oxidation.
1. Threaded connection brass ball valve: With standard internal and external thread structure, it is suitable for household water supply, floor heating circulation, and conventional water supply and drainage pipelines in commercial settings. The pipeline maintenance and disassembly are convenient.
2. Boiler brass ball valve: With enhanced high-temperature and high-pressure sealing components, it can withstand continuous circulation of hot and cold media from boilers. It is suitable for gas wall-mounted boilers and small industrial boilers for water inlet and outlet control.
3. Fire protection pipeline-specific valve: Compliant with fire protection pipeline pressure standards, with a structure that is resistant to vibration and can withstand high and low temperatures, it is suitable for spray network and fire hydrant pipelines, ensuring the long-term stable operation of the fire protection system.
1. The valve core is made of high-maintenance chrome-plated balls, combined with a fluorine seal seat. It operates smoothly when opening and closing, and after closing, it fits tightly to block the leakage channel of the medium.
2. The valve stem is equipped with multiple layers of high-temperature-resistant sealing packing. Under alternating temperatures and pressure fluctuations, it is less likely to cause valve stem dripping or pressure release failures.
3. Each unit is tested for water pressure airtightness upon leaving the factory. It simulates the long-term variable pressure operation environment to eliminate products with unqualified seals, thereby reducing the maintenance cost in the later stage of the project.
1. Standard universal BSP/NPT threaded type, no need for additional conversion connectors. It can directly connect to the mainstream water and heating pipe materials and equipment interfaces available on the market.
2. The valve body of the boiler and fire protection special valves has been optimized in shape, with a compact size. It can be smoothly installed in narrow boiler rooms, ceiling fire protection pipes, and pipe shafts.
3. There is no need for welding operations throughout the process. The assembly can be completed by simply screwing the threads together. There is no risk of open flame construction, significantly shortening the on-site construction period and reducing labor costs.
1. It supports bulk wholesale of goods, ensuring sufficient factory inventory, enabling quick delivery of large quantities of engineering orders, and shortening the customer's procurement cycle.
2. Customized services for specifications, packaging, and labels can be provided as needed, meeting the requirements of our own brand distributors for OEM production.
3. Complete qualification documents for shipment are provided, including material test reports, factory inspection certificates, and compliance certification materials, to meet the requirements for domestic engineering inspections and overseas export customs clearance.
