Product Information：
This Union Ball Valve is a copper valve under IFAN. Its biggest feature is that the port has a union, and it is an angle ball valve, the valve body is a two-color body, and the valve handle is a white aluminum butterfly handle.
Union Ball Valve is made of forged brass and consists of brass valve body, brass bonnet, brass ball and other parts; Union Ball Valve can be used in water, oil, gas and other pipeline systems, and the operating temperature standard is -40ºC to 150ºC. When water, oil, and gas flow from the inlet to the outlet of the ball valve, open the handle to flow out, and close the handle to stop. The size of the water flow and the opening and closing can be adjusted through the ball valve.

Product Features:
The basic function of the ball valve is to manually control the water flow switch and the size of the water flow. The live connection is to be able to disassemble it in the future to facilitate the maintenance and replacement of the system.
The difference between the PPR ball valve and the PPR live connection ball valve is that between the two sides of the PPR live connection ball valve and the pipe (hot melt), a (hot melt) union and (for the link) nut are added, which are convenient for disassembly and maintenance during maintenance. Replace the valve. The PPR ball valve does not have this union and can only be sawed off during maintenance.
The check valve is installed in order to ensure the flow direction of the water inside the pump, so as to ensure the normal operation of the pump. Therefore, the installation position of the check valve, whether it is installed before or after the pump, can be divided into two situations:
One is installed at the end of the vertical suction pipe in front of the water pump. The purpose is to fill the water pump without pumping water once, because when there is no water in the water pump and the suction pipe in front of the pump, the water pump can only run idling and cannot pump water, so the water pump must Water can only be pumped out when it is full of water. The installation of this type of pump is a method when it is above the liquid level. It is also called a negative pressure method. For example, the water is pumped up from a well. This method is used for secondary water supply. Since the liquid level is higher than the pump, it is not necessary to close the pump outlet valve when starting and stopping the pump, so the check valve should be installed behind the pump.
