Before the pump valve fittings are installed, the staff needs to carefully check whether the model, specifications, etc. of the selected product match the design. And according to the valve model and factory instructions to check whether the accessory can be applied under the required conditions. For example, when the valve is hoisted, the rope should be tied to the flange connection between the valve body and the bonnet, and should not be placed on the hand wheel or the valve stem to avoid damage to the valve stem and the hand wheel.
If it is necessary to install on a horizontal pipe, ensure that the direction of the pump and valve fittings is correct, and that the forced-to-mouth connection of the hard-wound shackles should not be used to avoid damage due to uneven force. It should be noted that the open gate valve should not be installed in the damp ground to avoid rust.
When assembling, it is important to ensure that the pump and valve fittings are clean. Moreover, the installation workshop must be clean, or a temporary clean area should be built to prevent dust from entering during the installation process. At the same time, the assembly tools used must be degreased before assembly to ensure cleanliness.www.dmgcastings.com
