What should I do if the pneumatic actuator of the pneumatic valve heats up?

The heating problem of the pneumatic actuator of the pneumatic valve may be caused by various reasons. The following are some common reasons and corresponding solutions: 1、 Air source pressure and flow issues Reason: Insufficient pressure or flow rate of the air source may result in poor movement of internal components of the actuator, leading to excessive heat generation. Solution: Check if the air source pressure is sufficient and if the flow rate meets the requirements. If there are any issues, consider increasing the size of the actuator or providing appropriate lubrication to improve the working conditions of the actuator.

The difference and selection between full bore ball valve and reduced bore ball valve

There are significant differences between full bore ball valves and reduced bore ball valves in terms of structure, applicable media, process requirements, advantages and disadvantages. When selecting, it is necessary to judge based on specific working conditions. The following is a detailed introduction: Difference 1. Definition and channel size Full bore ball valve: It is a flow channel with equal width, and the size of the holes from inflow to outflow is consistent. The size cannot be smaller than the standard specified value and is equivalent to the diameter of this specification. For example, the flow path diameter of a DN50 full bore ball valve needs to be around 50. Reduced diameter ball valve: The inlet of the flow channel is wider than the diameter of the flow channel, and the actual diameter of the flow channel is approximately one size smaller than this specification. The diameter of the DN50 reduced diameter ball valve channel is about 38, which is roughly equivalent to the specifications of DN40. Shrink one specification within DN250, two specifications between 250-600, and depending on the actual situation above 600. 2. Applicable media

What are the installation process and precautions for ball valves

The installation process and precautions of ball valves are key to ensuring their normal operation, extending their service life, and ensuring system safety. The following is a detailed installation process and precautions:  1、 Installation process  1. Preparation before installation  Check the valve: Confirm that the ball valve model, specifications, and design requirements are consistent, inspect the appearance for damage, and ensure that the components are complete.  Clean the pipeline: Remove impurities, welding slag, oil stains, etc. inside the pipeline to ensure cleanliness and prevent impurities from entering the valve and affecting the sealing performance.  Confirm pipeline support: Ensure that the pipeline can withstand the weight of the ball valve, and install support brackets if necessary to avoid valve damage due to pipeline stress.  Check the flow direction of the medium: Confirm that the installation direction of the valve is consistent with the flow direction of the medium
