The valve body is manufactured from ASTM A105 forged carbon steel, providing excellent mechanical strength, durability, and pressure resistance under demanding working conditions. The ball is made of F304 stainless steel for enhanced corrosion resistance and reliable sealing performance, while the stem uses F6a stainless steel material to ensure stable operation, wear resistance, and long service life.

Equipped with RPTFE (Reinforced PTFE) seats, the valve offers excellent sealing capability, low operating torque, and superior resistance to wear, chemicals, and high-pressure service environments. The lever operator design allows quick 90-degree operation for efficient flow control and easy maintenance.

This forged ball valve features a compact structure, reliable shut-off performance, anti-leakage design, and smooth operation, making it suitable for oil & gas, petrochemical, chemical processing, power generation, and general industrial pipeline systems. Manufactured with precision machining and strict quality control to ensure stable performance and long-term reliability in harsh service conditions.

The valve is a sleeve plug valve featuring a reduced bore design, engineered to optimize flow control while minimizing pressure drop and material cost. The valve body and plug are both constructed from UB6 alloy, a high-performance material known for its excellent resistance to corrosion, particularly in aggressive chemical and marine environments.

The internal sealing component is a PTFE (Polytetrafluoroethylene) sleeve, which provides superior chemical resistance, low friction, and reliable sealing performance over a wide range of temperatures. This ensures smooth operation, reduced torque requirements, and extended service life.

The valve is equipped with a gearbox operator, enabling precise and efficient manual operation, especially in applications requiring higher torque or where space constraints limit direct handle operation.

For enhanced safety and reliability, the valve is designed in accordance with fire-safe standards, ensuring that it maintains sealing integrity and operational capability even under fire exposure conditions. Additionally, it incorporates an anti-static design, which provides electrical continuity between the plug, stem, and body, effectively preventing the buildup of static electricity and reducing the risk of sparking in hazardous environments.

Overall, this valve configuration is well-suited for demanding industrial applications where corrosion resistance, operational safety, and durability are critical.
