Overview

Multi functional diaphragm solenoid valves are used for automatic control of refrigeration, pneumatic, and hydraulic systems. This series of solenoid valves is a pilot diaphragm structure solenoid valve, which can also be used in industrial sectors such as refrigeration, machinery, boilers, and fire protection.

Product Details

　　Structural characteristics of multifunctional diaphragm solenoid valve:

1. Widely used and diverse in models.

2. Small power, fast action, and lightweight appearance.

3. The applicable medium is limited and the adjustment accuracy is limited.

4. Easy to control internal leakage, completely block external leakage, and ensure safe use.

5. Easy to connect to computer, simple system, and low price.

　　Common installation problems of multifunctional diaphragm solenoid valve:

1. First, it is necessary to check whether the solenoid valve is consistent with the main parameters selected for the model, such as power supply voltage, material working pressure, pressure difference, etc. Especially for the switch power supply, if it is wrong, it will burn out the solenoid coil. The power supply voltage should consider the fluctuation range of the rated current working voltage: communication AC 10%~-15%, DC 10%~-10%. Ordinary electromagnetic coil components are not suitable for disassembly.

2. The magnetic coil component of a general solenoid valve should be perpendicular to the upward direction and perpendicular to the pipeline installed on the road surface. If it is necessary to install it sideways due to indoor space limitations or working conditions, it needs to be clearly stated when selecting and ordering the model. Otherwise, it will cause the solenoid valve to not function properly.

3. Before docking, the pipeline should be cleaned to eliminate any metal powder, rubber seal residue, rust, and other debris in the pipeline. Pay attention to the cleanliness level of the substance. If there is dust, residue, or other substances that hinder the normal operation of the solenoid valve, a filtering device or filter screen should be installed in the pipeline.

4. If substances can cause water hammer phenomenon, then electromagnetic valves with moisture-proof hammer function should be used or effective preventive measures should be taken.

5. Manual emergency shut-off valves should be added to the front, back, left, and right sides of the solenoid valve, and a bypass should be installed to facilitate maintenance of the solenoid valve during common malfunctions.

6. Electromagnetic valves are generally fixed and cannot be installed in reverse. They are usually placed on the valve body to emphasize the direction of material flow. When installing, they should be installed according to the direction indicated in →. But it can be reversed in the vacuum solenoid valve circuit or under special circumstances.

7. The steam solenoid valve channel side should be equipped with a steam drain valve, and the proportional solenoid valve should be skewed at this point.

8. As much as possible, it is not necessary to keep the solenoid valve connected to the power supply for a long time, as this can easily reduce the service life of the solenoid coil and even burn it out. In other words, open and close, normally closed solenoid valves cannot be interchanged for use.
