Fully Welded Ball Valve
Fully Welded Ball Valve
The body and connecting end of the fully welded ball valve are molded in one piece by a fully welded process. It eliminates the need for flanged connections, reducing potential leakage points and providing greater sealing and reliability. Compact and suitable for buried installation, it can withstand harsh operating conditions and extreme temperature changes.

Features And Benefits
All-welded ball valves are made of forged material, all-welded body instead of bolts and nuts, in order to avoid potential leakage of the valve body.The use of forged valve body can better protect the wall thickness, and avoid casting fluffing, trachoma and other casting problems.All-welded ball valves are available in spherical and barrel shapes.
All-welded ball valves are available in both spherical and barrel shapes, usually with a single weld in the spherical body and two weld seams in the cylindrical body.
Standards And Norms
The ball valves are designed in accordance with ISO14313 and API 6D international standards to meet the stringent requirements of high-pressure pipeline systems such as oil and gas. These standards ensure the stability of the ball valve in complex and severe working conditions, and are widely used in various industrial environments, especially for long-distance pipelines carrying oil and gas.
Structure And Sealing Performance
The simple and compact structure of the ball valve provides excellent sealing performance and low operating torque. In the process of operation, it can easily realize efficient sealing, not easy to leak, and at the same time to ensure the smooth flow of fluid, reduce energy consumption and operating difficulties.
Fully Welded Valve Body And Flow Resistance Design
The all-welded body design ensures that the valve will not leak during use. In addition, the valve is available in both reduced and through-diameter configurations, each of which effectively reduces flow resistance. The through-diameter design, in particular, offers virtually zero fluid resistance, which helps to improve fluid transfer efficiency.
Emergency Grease Filling
Equipped with emergency grease filling structure, allowing rapid lubrication and sealing in emergency situations, especially suitable for high pressure and high temperature and other severe working conditions. This design ensures that the valve maintains an efficient and stable working condition during operation and extends the service life of the equipment.
Automatic Pressure Relief Design
Built-in center cavity automatic pressure relief function, in the closed state of the valve, when the pressure in the center cavity is too high, it can automatically relieve the pressure to protect the equipment and piping system. This design effectively prevents damage to the equipment caused by overpressure and improves operational safety.
Low Leakage Packing
The use of low leakage packing ensures that the valve maintains excellent sealing under high pressure and high temperature environments. The low leakage design reduces the waste of resources and safety hazards caused by fluid leakage, and is suitable for industrial scenarios with high safety requirements.
Protective Design
Fireproof, anti-static and anti-stem blowout designs. The fireproof design maintains the sealing of the ball valve at extremely high temperatures; the anti-static function eliminates the risk of static buildup; and the anti-stem blowout design increases equipment safety by preventing the stem from being blown out due to excessive internal pressure.
Valve Seat Function
There are various valve seat configurations such as double blocking and double row, one side piston and one side automatic pressure relief and two side pistons, etc., which can be flexibly selected according to the specific application requirements. This combination of functions enhances the control capability of the valve and is particularly suitable for piping systems requiring double protection.
Extended Stem And Bonnet Construction
Extended stem and bonnet structure design can be adapted to specific environments such as deep wells, underground, etc., which is easy to operate and maintain, and at the same time increase the protection to avoid wear and tear or failure of the equipment due to environmental factors.
Anti-corrosion Design
Stainless steel can be over-welded on the surface of the valve body, valve seat or gasket support ring to provide excellent corrosion resistance. Even after prolonged use in underground environments, there is no internal corrosion, making it ideal for petrochemical and natural gas pipeline systems, providing long-term protection in critical application scenarios.
Long Service Life
Designed to last up to 30 years, this ball valve reduces the cost of frequent replacement and maintenance, making it particularly suitable for industrial projects that require long-term stable operation. Its high durability and reliability make it ideal for use in long running pipeline systems.
