A trunnion ball valve is a special type of ball valve in which the ball is connected to the drive unit via a trunnion. The trunnion design reduces the torque required for the ball to rotate, making trunnion ball valves particularly suitable for large piping systems. Furthermore, trunnion ball valves offer superior sealing performance and extremely low leakage rates, making them the preferred valve in many industrial sectors.
Product Features
Truncate Design
The trunnion structure ensures more stable ball rotation, reduces friction, and extends service life.
Suitable for high-pressure applications, providing excellent sealing performance and preventing media leakage.
High-Performance Materials
The valve body and ball are typically made of corrosion-resistant materials such as stainless steel and alloy steel, adapting to harsh media environments.
Sealing materials include PTFE, PPL, and hard alloys to meet various operating requirements.
Bidirectional Sealing
The fixed ball design achieves bidirectional zero leakage, ensuring system safety.
Low Operating Torque
The automatic pre-tightening design of the valve seat reduces the torque required for opening and closing, facilitating operation.
Long Service Life and Low Maintenance
Precision machining and high-quality materials ensure long-term stable operation of the valve, reducing maintenance costs.
Application Areas
Petrochemical Industry: Crude oil transportation, refining units, chemical reactors, etc.
Natural Gas Transportation: Long-distance pipelines, city gas distribution systems.
Power Industry: Boiler feedwater, circulating water systems, desulfurization and denitrification units.
Metallurgical Industry: High-temperature molten metal control, cooling water circulation.
Pharmaceutical and Food Industries: High-purity media transportation, meeting sanitary standards.
Mining and Paper Industries: Slurry transportation, wastewater treatment.
Technical Advantages
Pressure and Temperature Resistance
Nominal pressure up to 150LB~2500LB, temperature range covering -196℃ to +600℃, adaptable to extreme conditions.
Sealing Performance
Soft seals (such as PTFE) are suitable for low-temperature, low-pressure conditions; hard seals (such as hard alloys) are suitable for high-temperature, high-pressure environments.
Low Fluid Resistance
Full-bore design, low resistance during fluid flow, reducing energy consumption.
Quick Opening and Closing
Switching can be completed with a 90° rotation, fast response speed, suitable for emergency shut-off scenarios.
