Working principle and purpose of the product:

Internal thread globe valves are divided into two types: non-metallic seals and metal seals. In addition, external thread connected plunger valves are divided into two categories: Z-shaped and waist drum shaped. Their internal structures are completely the same and their uses are the same. They are mainly used in industries such as metallurgy, electricity, chemical, refining, and food. Used for opening and closing small diameter pipelines for water, steam, oil, etc. with pressure within 16-25kgf/cm2 and temperature below 250 ℃ to regulate flow.

Product Structure Features:

1. The structure is simple, and manufacturing and maintenance are relatively convenient.

2. Small work schedule and short opening and closing time.

3. Good sealing performance, low friction between sealing surfaces, and long service life.

4. The fluid resistance is high, and a large amount of force is required for opening and closing.

5. Not suitable for media with particles, high viscosity, and easy coking.

6. The adjustment performance is good.
