Although the stop valve is a type of valve product, it still has many special advantages compared with other products. For example, because it has a very reliable cutting function, it can be used as a cutting or regulating valve. As well as throttling; the excellent performance of media transport, cutoff, adjustment and other functions makes it able to meet the needs of special scenarios. In addition, the stop valves on the market can also correspond to a variety of manufacturer price points, providing consumers with reliable choices in different situations.

2. Specifications and models
There are many domestic manufacturers of stop valves, and most of the connection sizes are not uniform. It is mainly divided into the following categories: general category based on JB/T2203-1999 "Structure Length of Stop Valve". At present, most domestic stop valve manufacturers design and produce according to this standard. However, this standard is not perfect, and the specifications are incomplete. The maximum nominal diameter of a single gate stop valve is DN1200, and the maximum nominal diameter of a double gate stop valve is DN1500. According to the specifications of the stop valves produced by the manufacturer and the information available to them, the current minimum nominal diameter of the angle stop valve is DN15, and the nominal diameter of the Z-type straight-through stop valve reaches DN2000. After research, the connection sizes of various manufacturers are not uniform. In order to have a unified standard and allow users to interchange the same specifications when selecting and installing, it is recommended that the China General Machinery Research Institute revise JB/T2203-1999 "Structural Length of Stop Valve". It is recommended that design institutes and users select according to standards, and stop valve manufacturers design and manufacture according to standards.
Qualified stop valves should have the functions of medium transportation, cut-off, adjustment, etc., and they can be further divided into multiple styles according to different use needs and scenarios, such as low-temperature stop valves, Insulation jacketed stop valves, etc. are divided into straight-through stop valves, angle stop valves, etc. according to the direction of the channel. Therefore, the editor recommends that friends who are interested in purchasing in this area can choose according to their actual situation. If necessary, they can go through Make plans based on product experience in physical stores.
