Functions of a 3-Way Motorized Ball Valve: 

A 3-way motorized ball valve contains three openings. One is an inlet; the other is an outlet; the third can be either. It can also be an exhaust port that releases the pressure from within the valve. The inlet valves bring liquids or gases into the valve. At the same time, the outlet takes fluids out.

The primary function of a 3-way motorized ball valve is to control liquid flow from a pipeline. It can open or close the fluid flow. The exhaust port helps remove excess pressure from the valve. The valve can also divert the flow from one oath to the other.

The 3-way motorized ball valves perform another unique function. They can cut off the water supply from one section. Fluids can flow from another chamber without any disturbance. It is very beneficial if someone has to do maintenance work. 3-way motorized ball valves save from the problem of the complete shut-off. Instead, the flow from the defective side can be shut. These functions make 3-way for valves a favorite product.

Working of a 3-Way Motorized Ball Valve: 

A 3-way motorized ball valve has an electric motor that rotates the ball within the valve body. The ball has a while in the center. This aligns with the Inlet and outlet port. In an open position, it lets the fluid pass across. While in a closed position, it cuts off the supply.

The motor either contains a controller or a remote that sends a signal to open or close the valve. A stem lies in the center of the valve that connects the motor and the ball. The branch also rotates when the motor rotates, causing the ball’s station to. It then changes the aligning position of the valve, causing it to open or close.

The water flows from the Inlet and outlet if the alignment is with the openings. It blocks the fluids if it align with the valve body. A sealing surface lies on the ball. It tightly closed the valve when in the closed position. This element prevents leakages.

The working mechanism of a 3-way motorized ball valve is simple yet effective. It is a highly reliable product. The versatile nature of this valve makes it best for piping systems.

How to Install a 3-Way Motorized Ball Valve?

Installation of a 3-way motorized ball valve requires plumbing knowledge. As it has an electric motor, wiring is an essential element. The general steps for installation are as follows.

  • The process begins with shutting off the water supply. You can turn it off if you have a shut-off valve at a particular location. It is essential to stop fluid flow.
  • Next, select the correct location where you have to mount the valve. Choosing a side where the electricity supply is easy to access is better.
  • Cut the pipe from a specific location using a pipe cutter. You can mark the exact space and cut it where the valve will be installed.
  • Place the 3-way motorized ball valve and connect it with the Inlet and outlet pipes. Make sure there is no leakage by turning on the water supply.
  • The next step is to connect electric wires to the valve’s motor. It is essential to read and follow the instructions from the manufacturers. Every product can have different wiring instructions.
  • Generally, the wire from the main supply must connect to the motor’s terminal side. Sometimes, an extra wire is tied for the signals or controls.
  • If the valve has a manual operation, check its functioning manually. Otherwise, test the valve using the remote control. Follow the instructions on the package.
  • Now, turn the water supply on, which was cut at the beginning of the process.

The process is not very tricky, but it’s better to call a plumber if you are unfamiliar with wiring.
