Imported external thread angle needle valve
1、 Advantages and disadvantages of imported external thread angle needle valve structure:

The types of imported external thread angle needle valve are divided into external thread angle type and internal thread angle type according to the position of stem thread.

The imported external thread angle needle valve has the following advantages:
1. It is simple in structure and convenient in manufacture and maintenance.
2. The working stroke is small and the opening and closing time is short.
3. Good sealing performance, small friction force between sealing surfaces and long service life.

The disadvantages of imported external thread angle needle valve are as follows:
1. The fluid resistance is large, and the force required for opening and closing is large.
2. It is not suitable for medium with particles, high viscosity and easy coking.
3. The regulation performance is poor.

二、 Description of imported external thread angle needle valve:
German de lock imported external thread angle needle valve, also known as angle stop valve and angle instrument valve, is a kind of valve that can be adjusted accurately with good sealing performance. It is generally suitable for small flow, high temperature and pressure gas or liquid medium, and also suitable for use with pressure gauge.

三、 Technical specification for imported external thread angle needle valve:
1. Working pressure: ≤ 5000PSI;
2. Operating temperature: - 20 ℃ ~ + 200 ℃;
3. Size: ￠ 6 ～￠ 25;
4. Connection type: pipe butt welding connection, ferrule type;
5. Structural features: right angle type, conical seal, movable disc;
6. Valve body material: carbon steel, stainless steel, chromium molybdenum steel, etc;
7. Applicable media: water, oil, gas and other corrosive and non corrosive media;
8. Manufacturing standards: GB / t12224-2005, JB / t7747-1995;
