Special attention should be paid to those issues during valve installation and use.
Thread Content
I am a newbie and I don’t know what issues I should pay special attention to during the installation and use of gate valves. Please help.
There is no direction for gate valve installation. As long as you choose the right pressure, material, and nominal diameter, you can
Attention should be paid during the installation process: 1. Do not have any debris in the gate valve, such as sand, welding slag, etc. ； 2. During the installation process, lift it gently and position it smoothly to avoid damaging the valve flange surface. ； 3. The valve gaskets and fasteners should be installed evenly and in order to avoid uneven tightening of the valve body and uneven stress, and to avoid rework due to loose gasket sealing and leakage. Please pay attention during use: 1. The valve stem should be lubricated with grease to reduce wear on the valve stem packing. ； 2. When using the F wrench to open and close the valve, force should be applied evenly to avoid forced hard opening. ； 3. Pay attention to the wear of valve packing, and the packing gland can be tightened according to actual usage conditions.
There are no requirements for attention. The main thing is to select the correct type and install it in a convenient position for operation. If it is a newly installed pipe, it is best to purge the pipe before installation. After installation, do not close or fully open the handwheel. It is best to close it in place and then open it a little.
