Full Underground Welded Ball Valve OEM/ODM
The fully welded underground ball valve is designed to be used to reliably control the fluid flow in the buried pipeline. The integral welded body eliminates the outside leakage points, so it can be used for long periods of time in underground systems. They are widely used in petroleum, gas, water, sewage, and district heating.
Key Features
Durable and Durable Materials
The valve is made of corrosion-resistant material. Commonly used are carbon steel, stainless steel for corrosion, and alloy or high-temperature alloys for more demanding conditions. This ensures that the valve can cope with the harsh conditions in the ground without having to be replaced frequently.
Range of sizes
Available in sizes from NPS 1" to 24" or DN 25 – 600, the valve can fit small pipelines as well as larger industrial systems.
Pressure and Temperature
The valve operates in a wide range of pressures and temperatures. The pressure rating is usually in the ASME Class 150-2500 (PN 10-420), and the operating temperature can be between -60 ° C and + 250 ° C.
Different Seat Options
The seats may be made of PTFE, reinforced PTFE, nylon, Teflon or metal, depending on the liquid and conditions. This enables the valve to keep a good seal at various pressures and temperatures.
Flexible End Connections
End connections include Raised Face (RF) and Butt Welded (BW) options, making installation secure and reliable for buried pipelines.
Applications
- Petroleum and Gas Pipelines: Controls the flow of high pressure systems.
- Water Supply Systems: Efficient management of water pipes under the ground.
- Wastewater Treatment: Safe treatment of treated and untreated water.
- District Heating: Applicable to high temperature pipes.
Advantages of Underground Welded Ball Valve OEM/ODM Solutions
- Customizable Design: You can customize the valve to suit your needs, such as pressure, temperature, or chemical requirements.
- Reliable Sealing: Fully welded structure reduces leakage risk.
- Long Service Life: Durable materials and welded structures ensure the durability of products.
- Low Maintenance: Less external components can be easily repaired in hard-to-reach areas.
- Standards Compliance: API, ASME, and BS specifications can be produced.
