Is there a way to solve the automatic valve that is not controlled?

Uncontrolled? It is the actuator that is broken, the air pressure or power is damaged, or the signaling system is broken.

Is it a mechanical failure or a programming failure? What about electric or pneumatic valves? Or a differential pressure self-actuating valve?

Summary. The electric valve can be opened automatically, but it cannot be closed automatically.

The electric valve can be opened automatically, but it can't be closed automatically.

The electric valve can be opened automatically, but it cannot be closed automatically.

The input signal is interfered with and other problems cause the signal to run out of control2There is a problem with the controller inside the valve 3There are only two possibilities4The first is that you are monitored by the valve end block meter to see if the signal is normal when the valve is out of control.

The first is that you are under the monitoring of the valve end block instrument, to see if the signal is normal when the valve is out of control, if it is normal, it is the second reason, and it is OK to replace the internal control panel of the valve

Summary. If the control valve does not work in automatic mode, but it does work in manual mode, it may be due to one of several reasons:1

Power Issues: Auto mode requires power** and the control system must be properly powered. If there is a power failure or a problem with the control system, the control valve will not be able to enter automatic mode.

3.Improper control parameter setting: There may be some incorrect parameter settings during use.

For example, the set temperature range is too narrow, the error range is too large, etc. All of these can cause the control system to fail to enable the automatic mode. The above are only some of the possible causes, and they need to be investigated and judged according to the specific situation in the actual operation process.

It is recommended that you contact a professional technician for detailed inspection and repair processing.

If the control valve does not work in automatic mode but works in manual mode, it may be due to one of several reasons:1Power supply issues:

Improper control parameter setting: There may be some incorrect parameter settings during use. For example, the set temperature range is too narrow, the error range is too large, etc.

All of these can cause the control system to fail to enable the automatic mode. The above are only some of the reasons for the possible absence of the book, and it is necessary to investigate and judge according to the specific situation in the actual operation process. It is recommended that you contact a professional technician for detailed inspection and repair processing.

Don't be in a hurry when you encounter something, you must solve it rationally. Bring clarity to your thinking.

What is the voltage coming over the control valve.

The voltage coming from the control valve should be based on the specific use case, and different control valves may require different specifications of power supply**. Generally speaking, the common power supply for control valves is 220V or 380V AC. However, there are also some special occasions that require the use of other types of limb bridge power supplies, such as 24V DC power supply, 110V AC voltage, etc.

In actual use, you can check the equipment manual or ask the professional and technical personnel to understand the specific requirements and standards for the supply of lead.

It's the locator above.

A positioner on a control valve is a measuring device that is used to detect the position of a control valve. It usually requires the use of a power supply** to work so that the stool can accurately measure the valve bend position with an electronic signal. Specifically, the voltage required for the positioner will also vary depending on the model and specification.

In general, most positioners require a 24V DC power supply, and the actual installation and operation need to be properly connected and configured according to the relevant instructions. If you have more questions about the details of the equipment or need information about a specific brand or model, please consult a professional technician for more accurate and detailed guidance.

The electric valve can be opened automatically, but it can't be closed automatically.

Cause 1: Check whether the signal cable is short-circuited. After removing the control signal cable at the wiring port, see if the door leaf will be closed, if it can, it will prove that the signal cable is connected incorrectly, and the signal cable needs to be replaced.

Reason 2: The infrared sensor works continuously. The continuous operation of the induction sensor is generally that the induction probe is contaminated with too much dust or other foreign objects, if there is, it should be wiped off in time after inspection, so as not to affect the normal operation of the door opening and closing.

Reason 3: The sensor of the automatic door works continuously. This situation is mostly human interference, generally someone lingering near the sensor, or other flowers and trees that are easily blown by the wind, this situation can be pasted on the door glass with a warning:

It is strictly forbidden to play near the automatic door. Reason 4: Check whether there are foreign objects in the running rail, if there are foreign objects in the running track, the door will automatically start the self-locking function when it is running open and closed, so in daily use, it is necessary to clean the running track of the automatic induction door from time to time to maintain the daily cleanliness of the automatic induction door.

The main reasons why the ball valve cannot be opened automatically are as follows:1The pressure relief device is not closed

If there is a pressure relief device at the front of the ball valve and the pressure relief device is not closed, the ball valve cannot be opened automatically. 2.Failure of the operating mechanism:

The operating mechanism of the ball valve can be divided into two categories: manual and electric, and if the operating mechanism fails, it may cause the ball valve to fail to open automatically. 3.Clogged or damaged:

The inside of the ball valve may be clogged or damaged, preventing the ball valve from opening automatically. The handling method is as follows:1

Check whether the pressure relief device is closed: check whether the pressure relief device at the front end of the ball valve is closed, if it is not closed, close the pressure relief device and then try to slow the open combustion. 2.

Check whether the operating mechanism is normal: Check whether the operating mechanism of the ball valve is working normally, such as whether the manual operating mechanism is easy to rotate, and whether the electric mechanism has a power supply**. 3.

Clean the inside of the ball valve: If you find that the inside of the ball valve is blocked or damaged, you need to disassemble the ball valve and clean or replace the inside of the ball valve. It should be noted that caution must be taken when dealing with ball valve problems to avoid accidents caused by improper handling.

If you are not sure how to deal with it, it is recommended to ask a professional or relevant manufacturer to deal with Huai Guess.

Summary. Dear We are very happy to answer your <> one-on-one

Hello dear. The above is a detailed answer to the reasons why the ball valve cannot be automatically opened and the relevant questions about the Xiangyuan method of the banquet fight, I hope I can help you. Yamama <>

1. Detach the faulty valve from the automatic control system and become an independent valve that is only controlled by local manual control.

2. After the system is manual, the automatic control program can be disconnected to avoid the impact on the whole system due to the wrong operation of the faulty valve.

3. Safety. When dealing with valve failures, playing manual will avoid the sudden movement of the valve due to the system when dealing with the failure.

4. After playing manually, the manual control signal is introduced to facilitate the identification of the fault source. Is it a problem with the valve itself, or a problem with the control signal.

If you don't hit "manual control".

The system is still "auto-controlled".

When handling valves, the system does not know that it is artificial, and will mistakenly believe that the parameter changes will produce a coherent action, which will affect production.

It's dangerous.

You have to play "manual control".

Manual control is to prevent the control unit from being crushed when overhauling the faulty valve.
