What is a package solenoid valve?

Three-way diverter valve or package electric valve or motorized valve is a part in the wall package that is used to open and close the water flow path or radiator (heater). This part is only used in the two-converter package. As the name suggests, the three-way valve has three channels. (two outputs and one input). The main input of this valve is connected to the suction of the circulator pump. The outputs are one for hot water consumption (secondary converter) and another for heating radiators (heating system circuit).
Different package models have different solenoid valves, but ultimately they all have the same function.

Note :
The single converter package does not have an electric valve.

• How does the gas package solenoid valve work?
• The electric valve package includes two shut-off and shut-off valves, which are responsible for shutting off and connecting the gas flow. When the device does not work or faces a problem, it may be due to valve blockage and failure. It should be noted that for the package to work, both valves must be open, otherwise the package will not start working.
• In these valves, there is a spring that acts like a lever when opening and closing and causes them to move, and also when the output gas pressure is higher than the standard value, the pressure regulating valve is opened and reduces the gas pressure to the standard level. to reach the specified value. This part is very important and to repair it, it is better to contact Tehran service repairers.

How to set the solenoid valve of the gas package at maximum power:

First, you must remove the gas valve housing and open the upper screws on the left side and measure the gas pressure with a pressure gauge. In the next step, put the package at maximum power and leave the hot water tap open to the end. Now you have to measure the pressure, and if the amount of gas consumed does not match the gas in the package, set the settings to the standard mode with the polygonal nut that is in the device. If this problem is not due to incorrect settings, the problem is the failure of this part or other parts. It is better to ask a professional for help in such a situation.

How to test the solenoid valve of the gas package:

Before you replace the solenoid valve of the package, you must make sure that it is defective

We open the gas hose of the wall package from the part that is connected to the gas pipe of the house, and when the wall package is ignited, if the foot path is open by blowing into the gas hose, then the gas solenoid valve is healthy and otherwise defective, of course, it should be checked with an ohmmeter. Check the gas solenoid valve at the time of ignition

If the solenoid valve of the gas package is defective

The wall pack goes to the ignition stage, but the flame does not form

Installation location of gas package solenoid valve

It is located under the combustion chamber and before the gas manifold, and the gas hose of the wall package is connected to it.

Checking the three-way valve in the winter condition of the package

To check the winter status of the package and check the three-way valve, you must put the package in heating mode or winter mode. Check the temperature of the return pipe of the package, which is placed before entering the device and after the pump. If this pipe has a higher temperature in the part after the pump, the possibility of leakage in the three-way valve of the pump is high and it should be replaced.

If the o-ring of the three-way valve is not able to seal the path in winter, when we open the hot water valve, not all the hot water in the primary converter goes to the secondary converter, and some of it enters the radiators and finally causes the hot water Consumption is not hot enough and the efficiency of the package is also reduced.

Also, if you are constantly facing a pressure drop in your wall package, the pressure drop will appear in the digital wall package with the error code related to the pressure drop, and in the old wall package, it will show itself with the number corresponding to the pressure gauge screen. Most likely. There is a problem with the three-way valve of the wall package and you should repair the three-way valve of the wall package or replace the three-way valve of the wall package by skilled repairmen.
Changing the three-way valve of the wall package:

One of the indications for the need to replace the three-way valve of the wall package is the pressure drop, which you will regularly encounter with the error warning signs related to the water pressure drop. In this situation, it will be necessary to repair or replace the three-way valve of the wall package.

Steps for replacing the package solenoid valve:

First, we turn off the package
Second, we close the water inlet of the building.
Third, disconnect all three connections of the three-way valve, which are connected by pipes to the three-way valve of the package by opening the packages.
Connect the new 3-way valve to the 3-way fittings firmly with clamps. Be careful not to leak.

You can install the three-way valve in the forward or return direction and there is no difference. The only difference it can make is related to the life of the valves. If it is installed in the way, because there is always hot water, the possibility of damage to the parts of the three-way valve is more. The installation or replacement of the three-way valve of the wall package is mostly done in the return path due to the small space in the return path.

One of the things that should be paid attention to when replacing the three-way valve of the wall package is choosing and preparing a three-way valve suitable for your package model. It is better to make it from stainless steel and resistant to moisture and impact, because this piece is connected to electricity on one side and water on the other, so it must be of good quality.

Note: If the package’s water pressure drops regularly and the package gives a low water pressure error warning, it is likely that the package’s three-way valve will need to be repaired or replaced.
The cost of replacing the package solenoid valve:

The cost of replacing the package solenoid valve is different for different brands. According to market fluctuations, contact the specialists of Tehran Service to buy and replace your package solenoid valve.
