Differences between high-platform ball valves and ordinary ball valves, and their selection.

High-platform ball valves, also known as ball valves, are made by casting a square or round flange and the ball valve as a single piece, with the platform end face higher than the outer edges of the flanges at both ends. This not only facilitates the installation of pneumatic actuators, electric actuators, and other actuators, but also greatly improves the stability between the valve and the actuator, and makes the appearance more beautiful and refined.

High-platform ball valves are an evolution of conventional support-mounted ball valves. The difference lies in their direct connection to the actuator, eliminating the need for a separate support bracket, whereas conventional ball valves require a support bracket to mount the actuator. Besides eliminating the need for an additional support bracket, the direct mounting on the platform significantly improves the stability between the actuator and the ball valve.

The advantage of high-platform ball valves is that they can be directly fitted with pneumatic or electric actuators on their own platform, while ordinary ball valves require additional valve connections. This can lead to issues such as loose supports or excessive coupling clearance, which can affect the valve's performance during use. High-platform ball valves do not have this problem, and their performance is very stable during operation.

When choosing between high-platform ball valves and ordinary ball valves, the internal structure of high-platform ball valves is still based on the same opening and closing principle as ordinary ball valves. In addition to the advantages mentioned above, when the medium temperature is relatively high, a connecting bracket is required to protect the actuator and prevent the actuator from becoming unusable due to heat transfer from the medium.
