A ball valve must be used in the pipe transfer fluid to control the flow of fluid. However, in the fluid of all materials, different material ball valves have different performances, and the plastic ball valve is easy to operate because of its small size, light weight and light weight. It is most commonly used in life and work. When purchasing a plastic ball valve, how to choose the model to meet your own transmission needs, in order to maximize the effectiveness of the transmission. The following conditions should be considered when selecting?
First, fluid properties
No fluids have different properties, some are corrosive, some have high pressure, and some have relatively large viscosity. According to your own attributes, choose different types of plastic ball valves to meet the needs of the work. For example, corrosive liquids can not use ordinary plastic ball valves, which will directly lead to corrosion, so that according to different attributes, the utility is more practical, and the user is more convenient and the effect is better.
Second, temperature measurement
Some fluids have their own temperature, some are high temperature, and some are ultra-low temperature. Different temperatures have an impact on the performance of plastic ball valves. If the selection is wrong, the property will easily cause damage to the plastic ball valve, reduce its service life, and even cause the plastic ball valve to be abnormal immediately, which cannot be used for work.
Third, withstand the pressure of choice
Different pipes are different in size, and when they transfer fluid, the fluid creates pressure. In particular, plastic ball valves are pressure regulating instruments that cause it to generate more pressure. If the pipe is large, the plastic ball valve will increase accordingly. If the fluid cannot withstand the pressure, the plastic ball valve is directly damaged.
