Solutions to difficult opening and closing of large-caliber valves

1. Analysis of the reasons for the difficulty of opening and closing large diameter valves:

Analysis of valve market environment

According to the analysis of the valve market environment, the difference in valve consumption characteristics has led to a large difference in the development speed of the valve industry in developed and developing countries.

Pneumatic ball valve and pneumatic butterfly valve are more pros and cons

The pneumatic ball valve is a sphere, which uses the sphere to rotate 90° around the axis of the valve stem to achieve the purpose of opening and closing. Pneumatic ball valves are mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. The pneumatic ball valves designed with V-shaped openings also have a good flow adjustment function.

What is a high pressure gate valve? What are its characteristics?

The opening and closing part of the high-pressure gate valve is a gate. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The movement form of the valve stem includes a lifting rod type-the valve stem is raised and lowered, and the hand wheel does not lift, and there is also a lifting rotating rod type-the hand wheel and the valve stem rotate and lift together, and the nut is arranged on the valve body.
