The valve is a control switch used to manage the flow of fluid in the pipeline. There are many ways to change the media, depending on the type, the type is also different. It can be said that valves are a large category, with many types. It can be used to control the flow of water, steam, oil, gas, mud, various corrosive media, liquid metal, radioactive fluid and other types of fluids. The working pressure of the valve can be from 0.0013MPa to 1000MPa with ultra-high pressure, and the working temperature can be from c-270 ℃ to 1430 ℃ with ultra-low temperature. What are the installation requirements and precautions for the valve?

1、 What installation requirements does the valve have?

1. Before valve installation, carefully check whether the model and specification of the valve used are consistent with the design;

2. Check whether the valve can be used under the required conditions according to the valve model and factory instructions;

3. When hoisting the valve, the rope shall be tied to the flange connection of the valve body and bonnet, and shall not be tied to the handwheel or valve stem to avoid damaging the valve stem and handwheel;

4. When installing the valve on the horizontal pipeline, the valve rod shall be vertically upward, and it is not allowed to install the valve rod downward;

5. When installing the valve, it is not allowed to use the forced butt connection mode of drag and pull to avoid damage due to uneven stress;

6. The rising stem gate valve should not be installed in the underground wet place to avoid corrosion of the valve stem.
