The hemispherical fixed high platform ball valve is suitable for low temperature conditions, especially for handling hazardous media such as liquefied natural gas. It is very suitable for use in liquefied natural gas plants, docks, gasification stations, as well as liquefied natural gas transport ships and vessels.
● Extended Valve Cover: The valve and actuator can be placed at a considerable distance from the low-temperature process area to ensure the normal operation of the valve and prevent damage caused by freezing of low-temperature fluids.
● Low Operating Torque: Ensures more stable operation.
● Excellent Sealing Design: Minimizes leakage.
● Rigid Structure: Reduces 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 valves have high strength, corrosion resistance, and wear resistance, enabling them to operate stably for a long time in harsh working environments. The flange cast steel fixed high platform ball valve adopts advanced sealing technology to achieve zero leakage when closed, effectively preventing medium leakage and ensuring system safety. Suitable for industries such as petroleum, chemical, power, metallurgy, etc., meeting the control requirements of various complex media.
