Fully Underground Welded Ball Valve

Full Underground Welded Ball Valve OEM/ODM

A Fully Welded Underground Ball Valve is an essential component in fluid control systems used in critical underground pipelines. Designed for durability and leak-free operation in extreme conditions, these valves provide superior performance and reliability in a wide range of industrial applications. With a fully welded body, these valves eliminate the risk of external leakage and offer enhanced longevity, making them ideal for use in demanding environments like oil and gas, water supply, and utility infrastructure.

Key Features of Fully Welded Underground Ball Valves

Robust Materials for Maximum Durability
Fully welded underground ball valves are constructed from high-quality materials that ensure exceptional strength, corrosion resistance, and wear resistance. The most common materials used include:

      Forged Carbon Steel: Offers strength and durability for standard applications.
      Stainless Steel: Provides superior corrosion resistance for harsh environmental conditions.
      Duplex and Alloy Steel: Ideal for extreme environments that require high tensile strength and resistance to corrosion and pressure.
      Inconel: Suitable for high-temperature applications due to its excellent resistance to oxidation and thermal fatigue.

These materials are carefully chosen to withstand harsh underground conditions, ensuring long-term performance without the need for frequent replacements or repairs.

Wide Size Range
Fully welded underground ball valves come in a variety of sizes to meet the needs of different applications. The size range typically spans from:

      NPS 1" to 24" or
      DN 25 to 600

This flexibility allows for seamless integration into a wide range of pipelines, from small industrial systems to large-scale water and oil pipelines.

Pressure and Temperature Resilience
These valves are designed to operate under both high and low-pressure conditions. They are available in different Pressure Classes such as:

      ASME Class 150–2500
      PN 10–420

This range of pressure ratings ensures that fully welded underground ball valves can handle the requirements of diverse industries, from oil and gas to water treatment.

Additionally, they are built to function across a wide temperature range of -60°C to +250°C, making them suitable for both low-temperature and high-temperature applications in underground environments.

Multiple Seat Options for Different Applications
The seat material of a ball valve is critical to its sealing performance. Fully welded underground ball valves offer a range of seat options, depending on the type of fluid being transported and the operating conditions:

PTFE (Polytetrafluoroethylene): Ideal for general-purpose applications with low to moderate temperatures and pressures.
RPTFE (Reinforced PTFE): Provides enhanced strength and resistance to chemicals and high temperatures.
NYLON: Offers good wear resistance and is commonly used in fluid systems with moderate pressure and temperature conditions.
DEVOLON: A high-performance material suitable for demanding industrial applications requiring high wear resistance and strength.
Metal-to-Metal: Used in high-pressure and high-temperature applications, providing excellent sealing properties under extreme conditions.

Versatile End Connections
Fully welded underground ball valves come with a variety of end connection types to accommodate different pipeline designs. Common end connection options include:

      RF (Raised Face): A standard connection used in most industrial applications.
      BW (Butt Welded): Provides a permanent, high-strength connection, ideal for underground installations where long-term durability is required.

Applications of Fully Welded Underground Ball Valves

Fully welded underground ball valves are commonly used in the following industries and applications:

      Oil and Gas Industry: These valves are used in high-pressure pipelines, offering reliable fluid control and leak-free operation in harsh environments.
      Water Supply Systems: For controlling the flow of water in underground pipelines, ensuring efficient operation and minimal maintenance.
      Wastewater Treatment: These valves help in managing the flow of treated and untreated wastewater in underground piping systems.
      District Heating: Fully welded ball valves are ideal for controlling fluid flow in district heating systems, where high temperatures and pressures are common.

Advantages of Underground Welded Ball Valve OEM/ODM Solutions

Tailored Performance for Unique Applications
By opting for OEM/ODM services, you can tailor the valve's design and specifications to meet your exact application needs. Whether you need to handle high pressures, temperatures, or corrosive fluids, custom solutions ensure optimal performance and reliability in challenging underground environments.

Enhanced Sealing Integrity
The fully welded body construction of underground welded ball valves ensures superior sealing performance compared to traditional bolted valves. With no external leakage points, these valves provide a secure, leak-free solution that is essential for underground systems, where leaks can be difficult to detect and repair.

Durability and Long Service Life
Underground welded ball valves are designed to endure harsh conditions, including extreme pressures, temperatures, and corrosion. The welded body construction, combined with durable materials like stainless steel and alloy steel, guarantees long-lasting performance, reducing the need for frequent replacements or maintenance.

Reduced Maintenance Costs
Customizing the valve's materials, seat options, and other features allows for a more efficient, long-lasting solution. This not only enhances performance but also reduces the need for ongoing maintenance, which is particularly important for underground installations where accessibility and repairs can be costly and time-consuming.

Compliance with Industry Standards
OEM/ODM underground welded ball valves can be manufactured to meet various industry standards, such as API 6D, ASME B16.34, and BS 5351. These standards ensure that the valves meet the required safety, performance, and quality criteria, providing peace of mind for critical underground systems.
