3、 Overview of pneumatic high-pressure valves First of all, it is necessary to clarify the categories of valves. High pressure valves are also divided into several categories. There are overall models, two segment models and three segment models. Different models have different application methods. If there are special needs in special circumstances, you can avoid wrong operation by locking to ensure the normal operation of the system, Locking is actually a good choice. 　　

3、 When it comes to the selection of electric control valve, it is necessary to decide whether to purchase electric control valve controller additionally. However, due to the general state, the controller needs to be purchased separately. In most states, a single controller will be used, so you need to purchase a controller. If the electrical control performance cannot meet the requirements of engineering design, it needs to be proposed for modification or re design. Of course, the electric control valve should not only pay attention to the pipeline parameters, but also pay attention to the environmental conditions of obligations, because the electric device of this type of control valve is electromechanical equipment, and the obligation state will be greatly affected by the environment of obligations.
