Product advantages
The valve body adopts a forged steel all-welded ball valve structure, and the pipe is connected with a PE (polyethylene plastic) pipe. This steel-plastic composite design avoids the disadvantages of switch failure and damage caused by the aging of the valve body and the operating part material in the long-term use of pure PE ball valves, so it is not easy to cause leakage caused by aging and damage to PE, and the service life is long, and Safe and reliable, easy installation on site.
