1. The butterfly valve introduces foreign technology and is assembled by injection molding of high-density polyethylene and other engineering plastics. It has novel structure, beautiful appearance, acid resistance, alkali resistance, corrosion resistance, high mechanical strength and easy opening. is widely used. Used in chemical and acid processes, reducing liquid storage barrels, tanks, container outlet control valve. It can be used repeatedly, which helps protect the environment. 2. Working temperature -20 ℃ ~ + 70 ℃ 3. Working pressure < 0.15 MPa (test pressure 0.2 MPa) 4. The number of safe uses is 3,000 times, and it has passed the drop test. 5. The valve is used to control the outlet of the plastic container to prevent the liquid from splashing in all directions. Note: The data is manual measurement, please allow 1-3cm error, due to the differences between the light and the display, there will be a certain color difference, the specific received in kind prevail.
