The manual reversing valve is broken.

If your hot water meter solenoid valve is installed upside down, it may not work properly or cause problems such as water leakage. In this case, there are several workarounds to consider:

Correct the direction: Remove the solenoid valve, correct its installation direction according to the direction of the arrow on the solenoid valve, and then reinstall the solenoid valve.

Replace the solenoid valve: If the solenoid valve has been damaged or cannot be corrected, you can consider replacing the solenoid valve with a new one to ensure the normal operation of the hot water meter.

Seek professional help: If you are not sure how to correct the direction of the solenoid valve, or cannot solve the problem by yourself, you can contact a professional repair service provider or after-sales service center to get a more accurate solution.

It should be noted that when installing the solenoid valve, you should carefully look at the direction of the arrow on the solenoid valve to ensure that it is installed correctly. In addition, attention should be paid to the installation location during the installation process to avoid other problems.

If you put the solenoid valve upside down, the first thing to do is to make sure that it is safe, that is, to avoid any situation that may pose a threat to personal safety. Secondly, the solenoid valve should be reinstalled properly as soon as possible. The reason for this is that if the solenoid valve is not installed correctly, it is likely to cause leaks, failures, or not work properly.

In short: if you install the solenoid valve upside down, avoid any situation that may pose a threat to personal safety and reinstall the solenoid valve correctly as soon as possible; Otherwise, there is a high risk of leakage, malfunction, or failure to work properly.

It is equivalent to the intake and outlet air being reversed.

The trachea is installed with the original interface and then adjusted back.

The spool valve is stuck 2, the valve body is deformed 3, the centering spring with the middle position is broken 4, the operating pressure is not enough 5, the electromagnet coil is burned out or the electromagnet thrust is insufficient 6, the electrical circuit is faulty 7, and the hydraulic control reversing valve control oil circuit is oil-free or blocked.

Solenoid reversing valve, but what is wrong with the oil.

In the internal structure of the hydraulic solenoid valve, the gap between the valve core and the inner cavity of the shell is only about a gap, which belongs to precision parts, and its channel is just some small holes, and different flow directions are achieved through the moving position between different small holes. Therefore, the hydraulic solenoid valve is not oily, and the biggest possibility is internal blockage. Because the valve core and housing are precision parts, generally do not have the conditions for cleaning and installation, so the filtration of hydraulic oil is particularly important, which is easy to ignore.

Summary. Move to the right. Because when the power is on, it only opens the valve inside the pilot head.

Compressed air passes through this gate to push the stem to the right. The solenoid valve valve valve is not driven by electricity, but by the pressure of the compressed air itself. Electromagnetism is only an auxiliary role.

When the power is off, the pilot head is closed, and the valve stem returns to the position due to the action of the return spring (no spring for non-automatic return, with one more pilot head) and waits for the next power-on. Specifically, you can disassemble the valve and see it.

Solenoid reversing valve (3 positions), if the solenoid valve on the left is energized, how does the valve core move, and why.

Move to the right. Because when the power is on, it only opens the valve digging door inside the pilot head. Compressed air passes through this gate to push the stem to the right.

The solenoid valve valve valve is not driven by electricity, but by the pressure of the compressed air itself. Electromagnetic wisdom scattered code is only an auxiliary role. When the power is off, the pilot head is closed, and the valve stem is returned due to the action of the return spring (which is not automatic return without spring, and there is one more pilot head), waiting for the next power-on.

Specifically, you can disassemble the valve and see it.

Solenoid directional valves are a type of solenoid valves.

valvesIt is a control component in the fluid transportation system, with the functions of shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief.

Solenoid valves: It is a valve controlled by electromagnetic and is one of the basic components of automation used to control fluids. Generally refers to all valves controlled by solenoids; Specifically refers to (with other solenoid valves with descriptions, such as three-way solenoid valves, solenoid phantom valves, .......)In the case of parallel) solenoid valves with shut-off and diversion functions only.

Solenoid directional valve: Generally refers to a solenoid valve that can control the flow direction of the medium. In particular, it refers to the reversing valve used to realize the control logic in the hydraulic and pneumatic control system.

The following diagram illustrates the structure of a solenoid valve and a solenoid reversing valve.

Hydraulic valves (pneumatic valves, water pressure valves are not counted) driven by electromagnets include solenoid on/off valves, solenoid proportional valves, and solenoid servo valves.

Solenoid on-off valves include spool valve type, globe valve type (ball valve), and solenoid directional valve usually refers to two-position four-way and three-position four-way spool valve solenoid on-off valve.

It can be said that solenoid directional valve is a type of solenoid valve.

Solenoid, motor, electric heating, etc. are the driving methods, reversing valves, three-way diverter valves, three-way confluence valves, two-way valves, etc. are the functions of valves.

Solenoid directional valve is a kind of solenoid valve, there are normally open, normally closed, reversing valve, etc., simply understood - it is to open one road and close another road or multiple ways at the same time.

If the solenoid reversing valve needs to change the left turn to a closed right turn, it can be done in the following ways:1Exchange the two working ports of the solenoid directional valve.

If Port A is connected to Port B, and Port B is connected to Port A, the fluid flow direction will change. 2.Change the way the solenoid valve is energized.

Solenoid reversing valves usually have two coils, and changing the on-off sequence of the coils can change the flow direction. 3.Change the operating principle of the solenoid valve.

Some solenoid directional valves are closed and opened instead. 4.Replace the action movie assembly.

Some solenoid valve action plates are replaceable and can be changed by turning the action plate 180 degrees. 5.A double-acting solenoid valve is used.

By inputting different electrical signals, the valve can be converted left and right. 6.A valve answering gate with a fixed direction is added in the front and rear sequence of the valve, and the overall flow direction is changed with the help of the right turn effect of the valve.

7.Change the flow path pipeline before and after the valve, and adjust the flow direction before and after the valve to indirectly achieve the purpose of direction conversion. In short, according to the specific structure of the electromagnetic reversing valve, it is a common method to choose to change the power-on mode, change the action principle, and replace the internal action piece to achieve left and right switching.
