Before choosing a type of solenoid valve, sufficient information about the application must be gathered. This guide describes the key parameters for solenoid valves.
These are the most important guidelines when selecting a solenoid valve. Keep these guidelines in mind before choosing a valve.
Solenoid valves are very sensitive to dirt and only work with clean liquids or air.
Note that indirectly controlled solenoid valves require a permanent pressure differential of around 0.5 bar to function properly. Therefore, you can not use indirect operated valves in a closed circuit or systems with a low inlet pressure. Direct and semi-direct operated valves operate with a pressure differential from 0 bar.
Make sure that the used medium and temperature are compatible with the materials of the valve, such as body and the seal materials.
Solenoid valves open and close fast (between around 10 and 1000 ms). Improper use can cause pressure transients in the system (water hammer).
There are different types of solenoid valves, each with different principles of operation:
Direct operated (operating from 0 bar)
Semi-direct operated (operating from 0 bar)
Indirect operated (pressure differential required, normally at least 0.5 bar)
It is important to choose the right operation principle. Direct operated valves operate from 0 bar. In the valve there is a small orifice which is sealed off by a plunger with a polymer gasket. If the solenoid (electromagnet) is electrically energized, the plunger is lifted by the electromagnetic force and the valve opens. This principle is often used for small valves and is suitable for small flow rates. For larger flow rates, a semi-direct or indirect operated valve is recommended. Both make use of the medium pressure to open and close the valve. Semi-direct operated valves operate from 0 bar and often have a more powerful coil than indirect operated valves. Indirect operated valves need a permanent pressure differential of around 0.5 bar for proper operation. The advantage of indirectly operated valves is that they usually can control large flows with a relatively small coil and thereby have a reduced energy consumption.
Check if there is a permanent pressure differential over the valve of at least 0.5 bar. In this is the case, an indirect operated valve may be chosen (a semi-direct valve is of course also allowed in this case). If this is not the case (low inlet pressure, closed circuit, ..), choose a (semi-)direct operated solenoid valve.

Air source treatment is the component working by using the pressure of the gas or the expansion of the force. It Includs air filter, pressure regulating valve, oil lubricator, etc. Pneumatic products are widely used in metallurgical mechanical and electrical, construction, transportation equipment, home appliances, light industry, machine tools, medical, packaging industry and other industries automation production. However, because the compressed air can not be directly used t, it contains a certain amount of moisture, oil and dust. After compression, the air temperature is as high as 140-170℃, and some of the water and oil have become gaseous. Therefore, it is necessary to use the compressed air after purification treatment to run the mechanical equipment.
The air source treatment includes air filter, pressure reducing valve and oil lubricator. Some companies’ solenoid valve and cylinder can do oil-free lubrication (lubricating air by grease), which does not need to use oil mist device. The filtration degree is generally 50-75μm, the pressure regulating range is 0.5-10MPa, if the filtration accuracy is 5-10μm, 10-20μm, 25-40μm, and the pressure regulating is 0.05-0.3Mpa, 0.05-1Mpa three large pieces of no pipe connected components called three coupling. The three components are indispensable air source devices in most pneumatic systems. They are installed near the gas equipment and are the final guarantee of compressed air quality. The installation sequence of the three pieces is air filter, pressure reducing valve and oil mist device according to the inlet direction. The combination of air filter and pressure reducing valve are called pneumatic coupling. We can also set air filter and pressure reducing valve together, it becomes a filter regulator (function and air filter and pressure reducing valve combined with the use of the same). Oil mist in the compressed air is not allowed in some occasions. It is necessary to use the oil mist separator to filter out the oil mist in the compressed air. In summary, these components can be selected as needed, and they can be used in combination. The air filter is used to clean the air source. It can filter the moisture in the compressed air and avoid the moisture entering the device with the gas. The pressure reducing valve can stabilize the pressure of the air source, so that the air source is in a constant state, and the damage to the hardware such as the valve or actuator can be reduced due to the sudden change in the air pressure of the air source. The filter is used to clean the air source. It can filter the water in the compressed air and avoid the water entering the device with the gas. The oil mist can lubricate the moving parts of the machine body, and can lubricate the parts that are not convenient to add lubricating oil, thus greatly prolonging the service life of the machine body.
BLCH Pneumatic Science and Technology Co. Ltd was founded in August 2004, it is located in the YUEQING economic development industrial zone. The company covers an area of 24000
In order to further implement the security work and improve the emergency handling capacity of the company’s production staff, At 4 PM on May 21, BLCH Pneumatic Technology Co., Ltd. carried out fire emergency drill and training, and invited Yueqing Antong Safety Technology Service Co., Ltd. to participate in the on-site guidance.
Urgent notice: “the company first floor waste warehouse fire!”As the fire control room alarm sounded, the fire drill officially began.
The security team quickly closed the fire surrounding, and call 119 for support; The evacuation team guided the personnel to immediately implement the fire fighting, and finally the fire was under control, and the on-site personnel were transferred in time. During the exercise, each teams responded positively, their responsibilities were clear, and the exercise procedure was well organized and orderly.
After the fire drill, we organized to learn the early fire fighting knowledge evacuation and escape knowledge and fire extinguishers and other fire equipment correct operation method on the site.
The fire emergency exercise fully enhanced the awareness of fire safety of all the staff of the company, strengthened the knowledge of fire safety and the actual combat skills of the correct use of equipment.
