Brass flange check valve

Brass flange check valve is a widely used Universal valve product that can be used to control the flow direction of fluid in pipelines and prevent fluid from flowing back. Its main material is brass, which has corrosion resistance and is widely used in industrial piping systems.

Brass flange check valve is suitable for low-pressure systems. It has the advantages of simple structure, small size, light weight, and easy installation, making it one of the necessary valve products in many industries. Below, we will introduce in detail the structure, working principle and application scope of the brass flange check valve.

First, let’s take a look at the structure of the brass flange check valve. It consists of valve body, valve cover, valve disc, spring and flange. The control valve body and valve cover are made of brass material with good corrosion resistance and sealing performance. The valve disc can automatically close and open through the action of the spring, ensuring that the fluid can only flow in one direction. The flange can be easily connected to the pipeline to ensure the stability and sealing of the valve.

Secondly, let’s understand how the brass flange check valve works. When the pressure of the fluid is greater than the pressure on the upstream side of the valve disc, the valve disc will automatically close to prevent the fluid from flowing back. When the fluid pressure is less than the pressure on the upstream side of the valve disc, the valve disc will be pushed open by the fluid, and the fluid can pass through the valve smoothly. When the valve disc is closed, a seal is formed between the valve disc and the valve seat to prevent fluid leakage.
