Overview of 314 brass flange globe valve

Brass flange globe valve is a closed circuit valve that fully connects or cuts off pipelines. It is widely used and has the characteristics of frictionless sealing surface, small opening height, single-sided sealing, material saving, low cost, and easy maintenance. Copper valves used for pipelines and blast furnace soft water eliminate corrosion and unsafe factors.

Copper globe valves have the following advantages:

1. Copper globe valves have a simple structure and are relatively easy to manufacture and maintain.

2. Copper globe valve has a small working stroke and short opening and closing time.

3. Copper globe valves have good sealing performance, low friction between sealing surfaces, and long service life.

The disadvantages of copper globe valves are as follows:

1. Copper globe valves have high fluid resistance and require significant force to open and close.

2. Copper globe valves are not suitable for media with particles, high viscosity, and easy coking.

3. Copper globe valves have poor regulating performance.

The installation and maintenance of globe valves should pay attention to the following matters:

1. The shut-off valve operated by handwheel and handle can be installed at any position in the pipeline.

2. Handwheels, handles, and dynamic mechanisms are not allowed for lifting purposes.

3. The flow direction of the medium should be consistent with the arrow direction shown on the valve body.
