Product Description
 

Product Usage

Fully welded ball valves with integral welded valve bodies provide exceptional sealing, effectively eliminating external leakage. These valves are renowned for their superior quality and high-performance stability, far surpassing ordinary cast steel ball valves. With a service life significantly longer than cast steel counterparts, fully welded ball valves are extensively utilized in city gas, city heating, petrochemical industries, shipbuilding, steel manufacturing, pressure regulating stations, power plants, and various types of pipeline systems.
Welded ball valves come in a variety of colors, including blue, yellow, grey, and black. They can be operated through different transmission methods such as handle, worm gear, pneumatic, and electric actuators.

Construction Characteristics

  • Fully welded housing;
  • Trunnion mounted ball;
  • Spring-loaded seat rings;
  • Metallic or soft seals;
  • "Double Block and Bleed" design;
  • Full or reduced bore;
  • Flanged, welded, or threaded connections;
  • Blow-out proof shaft;
  • Shaft seals replaceable under full pressure in both open and closed positions;
  • No static charging;
  • Maintenance-free bearings;

Applicable Standards

  • Design & Manufacture: Conforms to API 6D/ISO 14313, ASME B16.34
  • Connection Dimensions: Conforms to ASME B16.25, DIN EN 12627
  • Fire Resistance Design: Conforms to API 607/ISO 10497
  • Inspection & Testing: Conforms to API 6D, ISO 5208, API 598
  • Material: Conforms to ISO 15156

Fully Welded Ball Valve Performance

  1. These valves require no maintenance, adjustments, or lubrication, making them easy to install and highly reliable for long-term use at low operational costs. The surface features a lustrous, beautiful spray treatment technology, positioning it at the forefront in China.
  2. The valve's surface undergoes a specialized plastic spraying treatment, which imparts a beautiful luster and ensures no external leakage. The welded valve body is lightweight and easily insulated.
  3. The operating handle is designed for easy removal and reinstallation in different orientations.
  4. The valve seat incorporates a carbon fiber reinforced PTFE seal ring and a disc spring, providing high adaptability to pressure and temperature changes without leakage within the specified range.
  5. Enhanced adaptability to pressure and temperature changes is achieved through a carbon fiber reinforced PTFE seal ring and disc spring, ensuring no leakage within the specified range.
  6. Advanced computerized testing processes the ball with high precision, ensuring optimal performance.
  7. The valve body, constructed from the same material as the pipeline, ensures uniform stress distribution, resistance to deformation from earthquakes or heavy traffic, and superior aging resistance.
  8. Features include integral fully welded structure, equal and variable diameter channels, fixed and floating balls, a double piston effect sealing system, and automatic injected sealant type bearings.
  9. To prevent static electricity, the stem and ball, as well as the stem and stuffing box, are equipped with steel balls and springs. This maintains conductivity through the valve body, discharging static electricity to prevent fire, corrosion, and allowing for timely maintenance.
  10. The anti-disengagement stem design ensures stability under pressure, maintaining the stem securely in place to prevent disengagement.
  11. Engineered with a low friction material thrust washer, this innovative support system ensures that the pressure is effectively transferred against the stem. As a result, the stem operates solely as a torque transmitter, enhancing the overall efficiency and reliability.
Diverse Applications of Fully Welded Ball Valves
  1. City Gas Systems: Seamlessly manage gas output pipelines, main lines, and various branch supply pipelines with unmatched precision.
  2. Central Heating: Optimize the performance of large heating equipment output pipelines, main lines, and branch lines for maximum efficiency.
  3. Heat Exchangers: Effortlessly control pipelines and various circuits for smooth opening and closing operations.
  4. Steel Plants: Efficiently handle various fluid pipelines, waste gas selective discharge pipelines, gas and heat supply pipelines, and fuel supply pipelines for superior performance.
  5. Industrial Equipment: Perfect for a wide range of industrial applications, including various heat treatment pipelines and industrial gas and heat pipelines, ensuring robust and versatile performance.
