Reduction Welding Ball Valve

Our Reduction Welding Ball Valve is engineered to meet the strict requirements of industrial pipeline systems, focusing on solving the pain points of traditional valves such as easy leakage, poor pressure resistance, and short service life. The valve body is integrally formed by pressing carbon steel seamless steel pipes, with a stainless steel ball core and carbon-reinforced PTFE inclined elastic sealing ring, which achieves absolute zero leakage by applying negative pressure on the spherical surface. The reduced-diameter structure optimizes the flow resistance while ensuring the strength of the valve, making it suitable for both high-pressure and high-temperature working environments, and perfectly compatible with various pipeline connection needs.

With advanced manufacturing technology and strict quality control, this valve not only has excellent sealing performance and corrosion resistance but also features light weight, compact structure, and easy installation, which can greatly save construction costs and engineering time for your project. It is widely recognized in the global market for its reliability and durability, complying with international standards such as ISO, DIN, API 6D, and PED 2014/68/eu, and has passed CE certification, ensuring stable operation in various complex working conditions.

1.Zero Leakage Sealing Performance : Adopting carbon-reinforced PTFE (RPTFE with 20% carbon content) sealing ring and butterfly spring structure, the valve seat has strong adaptability to pressure and temperature changes, ensuring no internal or external leakage within the rated pressure and temperature range. The precision-ground stainless steel ball core further enhances the sealing tightness, effectively preventing media loss and safety hazards.

2.High Strength & Stability : The valve body is made of integral forging (A105, ST37.0, A106-B, etc.), which has high structural strength and excellent resistance to axial force, avoiding deformation caused by geological subsidence, earthquakes, or ground vehicle pressure. The material of the valve body is consistent with the pipeline material, ensuring uniform stress and long-term anti-aging performance.

3.Low Flow Resistance & Energy Saving : The optimized reduced-diameter flow channel design minimizes the flow resistance coefficient, which is the smallest among all valve types. It can reduce energy consumption during media transportation, improve pipeline efficiency, and is suitable for the transportation of viscous fluids, slurries, and solid particles in addition to general media.

4.Easy Installation & Maintenance-Free : The full welding connection method saves flanges, gaskets, bolts, and other accessories, reducing installation steps and costs. The valve can be directly buried underground without building large valve wells, only requiring small shallow wells on the ground, which greatly shortens the construction period. It requires no regular maintenance, adjustment, or lubrication, realizing long-term reliable operation with low operating costs.

5.Multiple Safety Protection : Equipped with anti-static and fire-proof functions, steel balls and springs are installed between the valve stem and the ball core, as well as between the valve stem and the stuffing box, to ensure electrical conductivity of all parts and release static electricity in a timely manner, preventing fires and corrosion. The valve stem is designed with an anti-falling structure to avoid the valve stem flying out due to pressure surges, ensuring operational safety.

6.Flexible Operation & Customization : The operation method supports manual (handle rotation 90° to complete opening and closing), gear (vertical/horizontal), electric, and pneumatic drive, which can easily realize remote operation and automatic control. The length of the valve body and the height of the valve stem can be adjusted according to construction and design requirements, and the material and specifications can be customized according to specific working conditions.
