Pump and valve fittings are a kind of mechanical products widely used in national economic construction. In the current market, more and more common valve types are ball valves, globe valves, gate valves, butterfly valves and regulating valves. In practical applications, the pump valve fitting valve must be installed correctly when it is installed.
Usually when installing a pump valve fitting valve, it is required to position it before the pipeline is installed. At the same time, it should be noted that the piping should be natural, the position is not right, can not be hard to avoid prestressing, and it is recommended to install with a lifting ring when installing. When installing with chain, pay attention to the protective measures for the outer coating of the valve.
It should be noted that during installation, if the valve of the pump valve fitting has a bracket or transmission mechanism at the same time, the sling should be fixed on the valve sling, and the sling should not be placed on the transmission mechanism; the sling or the hoisting chain cannot Squeeze the valve external fittings and their extension rods to avoid damage to the valve actuators, resulting in the valve not being able to switch or switch.http://www.dmgcastings.com/
