control module
valve stem and actuator push rod
The valve stem is connected to the actuator push rod. As can be seen from the figure, the valve stem and the actuator are a [flexible] connection structure, the purpose of which is to adapt the actuator thrust to the closing force required by the control valve, compensate for the thermal expansion of the control valve stem caused by temperature, and ensure the "thrust and stroke" valve position end limit closure.
Sleeve guided control valve
The sleeve-guided control valve is a control valve with large capacity, wide adjustable range, high flow characteristic accuracy, excellent dynamic stability, and a structural design that improves the smooth flow of fluid. It is suitable for control valves under harsh working conditions.
