The hemispherical fixed high platform ball valve is suitable for low temperature conditions, especially for dangerous media such as liquefied natural gas. It is suitable for LNG plants, LNG terminals, LNG gasification stations and LNG transport ships and vessels.
● Extended Valve Cover: The valve and actuator can be kept at a large distance from the low temperature process area to ensure that the valve can open and close normally and prevent damage caused by freezing of low temperature fluid.
● Low Operating Torque: More stable operation.
● Excellent Sealing Design: Minimize leakage.
● Rigid Structure: Reduce thermal shrinkage.

Q1: What makes the side-entry structure beneficial?
A: It allows for easy internal maintenance without removing the valve from the line, reducing downtime and service complexity.
Q2: Is this valve suitable for automation?
A: Yes, the valve supports manual, pneumatic, and electric actuation for flexible control options.
We use high-quality cast steel materials to ensure that the valves have high strength, corrosion resistance, and wear resistance, enabling them to operate stably over long periods in harsh working environments. The flanged cast steel fixed high platform ball valve employs advanced sealing technology to achieve zero leakage when closed, effectively preventing medium leakage and ensuring system safety. It is suitable for industries such as oil, chemical, power, and metallurgy, meeting various complex medium control requirements.
