Therefore, for a negative pressure solenoid valve, it is essential that its leakage rate be zero. How is the leakage rate of such a solenoid valve determined? It is based on the negative pressure value of the valve Normally, negative pressure solenoid valves require a very low leakage rate; they are also known as zero-leakage solenoid valves, negative pressure solenoid valves, or vacuum solenoid valves. There are also micro-high-frequency solenoid valves and high-frequency solenoid valves, with a maximum frequency of 100 Hz or 200 Hz ； High-frequency solenoid valves can be used for pressure compensation, as well as as regular solenoid valves to regulate flow and compensate for pressure. High-frequency solenoid valves are cheaper than regular ones and yet reliable.

This is especially true for devices that are used for research and analysis, where strict requirements are placed on various parameters, such as those applied to solenoid valves, which are common automation components. There are relatively few manufacturers that conduct research on the various performance parameters of solenoid valves as individual components. The key performance indicators of solenoid valves here (i.e., the reliability-related metrics of solenoid valves) include things such as the switching response time of the solenoid valve, its leakage rate, and the temperature rise it experiences. The performance specifications of some solenoid valves currently available in China are designed by major domestic manufacturers with reference to American standards; even the current national standard GB either directly cites or equivalently adopts those American standards ； Such as GB/T4213-92 (valve leakage standard) ； The equivalent standard is ASME B16.104 in the United States; there are only minor differences in terminology and classification, but it is referenced on an equivalent basis to the national standard. For example, control valves are just different from solenoid valves, which we are studying now. GB/T4213-92: (Leakage standards) Leakage grade, test medium, test pressure, maximum leakage rate at the valve seat, 1/h: Ⅰ – to be determined by the user and the manufacturer; Ⅱ – water, air, or nitrogen; A5×10-3×valve’s rated capacity; Ⅲ – 10-3×valve’s rated capacity; Ⅳ – water A or B: 10-4×valve’s rated capacity; air or nitrogen A: Ⅳ-S1; water A or B: 5×10-4×valve’s rated capacity; air or nitrogen A: Ⅳ-S2; air or nitrogen A: 2×10-4×△P×D V; water B: 1.8×10-7×△P×D; VI – air or nitrogen A: 3×10-3×△P. (Continued table for leakage rates.) According to American standards: Leakage grade, maximum allowable leakage rate, test medium, test pressure: Ⅱ – 0.5%Cv; air or water at 10–52°C, maximum operating pressure difference △P or 501 b/in2, whichever is lower; Ⅲ – 0.1%Cv; air or water at 10–52°C, maximum operating pressure difference △P or 501 b/in2, whichever is lower; Ⅳ – 0.01%Cv; air or water at 10–52°C, maximum operating pressure difference △P or 501 b/in2, whichever is lower; V – for each inch of nominal diameter and each pound per square inch of pressure difference, an allowable leakage rate of 0.0005 ml/min; water at 10–52°C, maximum operating pressure difference △P; VI – valve’s nominal diameter, ml/min, number of bubbles per minute; air or nitrogen at 10–52°C, maximum operating pressure difference △P or 501 b/in2, whichever is lower, in mm: 1250.151, 1.5380.302; 2510.453, 2.5640.604; 3760.906, 41021.7011; 61524.0027; 82036.7545. The leakage rate of solenoid valves is not related to the size of the valve body; what affects leakage is the medium, medium temperature, sealing material, and sealing structure. Valves that can achieve a leakage performance level of VI generally have very good sealing properties, with a leakage rate of around 0.00007 cc/sec. In American-standard industries, the volume of one bubble is usually 0.15 ml; at a temperature of 18°C and under standard atmospheric pressure. It is usually referred to as a zero-leakage seal. Such a sealing structure is typically designed specifically for this purpose; it must be made of an elastic sealing material, and the purity of this material is required to be as high as 97%. For example, take the vacuum and zero-leakage solenoid valves that we study – the bubble-level sealed solenoid valves produced by this company have a leakage rate of 0.00003 cc/sec; not even one bubble is generated in an hour. Moreover, they feature a high switching frequency, with a switching response time of 4–16 ms. They claim to supply 90% of the solenoid valves used in the aviation industry (including ground equipment). Of course, precision energy analysis devices as well as biochemical analysis devices also use PeterPaul solenoid valves from the United States, with Agilent being one example of such devices. They have maintained close operational ties with NASA, including NASA’s annual assistance in production management. At present, domestic solenoid valve manufacturers have rudimentary equipment, and it is simply not possible to conduct any research on the performance parameters of these valves. Moreover, the operational lifespan of most domestic solenoid valve manufacturers is around 5 years. This forces many customers to consider future after-sales issues when working on equipment and engineering projects. Without proper support services, customers will not choose domestic products, and they are also worried that they might not be able to find the manufacturers in the future. The solenoid valve is one of the core components in automated equipment, and it is also a component whose performance parameters have an impact on the entire machine or the whole manufacturing process – an impact that many engineers tend to overlook. Many engineers in China consider a solenoid valve to be nothing more than a simple valve used for opening and closing But what they didn’t realize is that several major international brands invest tens of millions of dollars each year in optimizing the various performance parameters of solenoid valves; achieving even a reduction of 3ms in switching time or a decrease of 2k in temperature rise requires significant effort. For good solenoid valves, one should consider their CV value, their temperature rise, their switching response time, and their leakage rate. Other indicators, such as pressure, power consumption, explosion protection, and corrosion resistance, only become relevant under the condition that the first 4 basic indicators are met.

Zero leakage and rapid switching response are characteristics of an excellent solenoid valve; it is suitable for use with media such as compressed air, water, hydrogen, nitrogen, and other gases or liquids. Currently, this solenoid valve is standardly available in two full-bore sizes: 1/4” and 1/2” ； To prevent leaks and blockages, we recommend installing precision filters with a precision of 30 ~ 60μm on the pipes; we have designed a special installation method involving embedded assembly ； Guaranteed maximum burst pressure: 20,000 PSI, maximum operating pressure: 10,000 PSI, with leakage rate requirements compliant with American Standard Class 5. This series of solenoid valves are pilot-operated solenoids, yet they offer a zero-leakage guarantee; the operating pressure is 100 PSI ； Normally closed solenoid valves need to be installed vertically. In addition to meeting all the application requirements of the EH40 series valves, the EH50 series solenoid valves feature a special design: a check valve is installed inside the solenoid valve channel to ensure safety against reverse fluid flow and prevent leakage.

We can provide professional custom development of solenoid valves, filters, micro motors, and fluid control integrated modules for customers. As the first supplier in China to offer deep-sea submersible high-pressure seawater solenoid valves, seawater solenoid valves, and energy-saving solenoid valves for deep-sea applications, Shenzhen Deteng Electromechanical Equipment Co., Ltd. supplies thousands of sets of high-pressure seawater solenoid valves with pressures of 3000 PSI (21 Mpa) and 6000 PSI (42 Mpa) to domestic providers of deep-sea equipment. These solenoid valves are capable of operating without continuous power supply, are energy-efficient, and only require a short period of power activation to maintain their on/off state. The high-pressure seawater solenoid valves are made from special materials such as Monel alloy. We have many years of experience in the application of solenoid valves in deep-sea equipment. Especially with the current government incentives, many manufacturers fail to pay attention to detailed aspects, which leads to various problems such as high energy consumption in deep-sea control systems and corrosion caused by seawater. Our deep-sea solenoid valves do not require continuous power supply during operation, and we use special materials resistant to seawater corrosion. Our products include deep-sea submersible solenoid valves, seawater solenoid valves, energy-saving solenoid valves for deep-sea use, high-pressure seawater solenoid valves, and zero-leakage high-pressure solenoid valves. Their unique sealing design, featuring a conical seal, ensures an adequate contact area and reduces flow resistance. With a maximum pressure of 100 MPa, these are direct-acting ultra-high-pressure solenoid valves with a conical design that guarantees zero leakage at high pressures. They are also high-flow, high-pressure solenoid valves that are leak-free. Whether it’s direct-acting high-pressure solenoid valves or zero-leakage solenoid valves, including those that function at low temperatures, we have the right low-power, zero-leakage solenoid valves available in our product portfolio. There are also some new component suppliers who claim to be able to provide high-pressure solenoid valves, filters, and other products without any actual experience, which has caused losses for many companies in China. We have over 100 years of experience in manufacturing solenoid valves, with extensive expertise in the optimized design of fluid control systems. We also have more than a decade of experience in the use of these valves in hydrogen-related applications in the United States. You need to be particularly careful when choosing solenoid valves for hydrogen use; our valves are designed for high-pressure, high-temperature, as well as ultra-low temperature applications ； Without decades of experience in manufacturing high-pressure special solenoid valves, as well as experience in hydrogen applications, it is impossible to ensure the efficiency and reliability of your hydrogen equipment ； There are low-pressure solenoid valves available for hydrogen fuel cells, and we also offer high-quality products for these. The commonly used pressure rating for seawater solenoid valves internationally is 21 Mpa. At present, Shenzhen Deteng Electromechanical Equipment Co., Ltd. is able to supply seawater solenoid valves, submersible solenoid valves, and deep-sea solenoid valves with a pressure rating of up to 100 MPa; currently our main products are those with 21 MPa and 42 MPa pressure ratings. In the future, we will continue to develop seawater solenoid valves of various flow rates and pressure levels that meet market demands. The highest pressure level achievable through our technology is 10,000 PSI (100 MPa), which provides a technical foundation for further expansion in the market. The high-pressure seawater solenoid valves we offer have a pressure rating of 42 MPa ； Over the next decade, the scale of China’s marine economy industry is expected to reach 10 trillion. Currently, various companies in this sector are actively contributing to its development, including those involved in seawater drilling platforms, AUVs, ROVs, and other deep-sea drones.

Therefore, for a negative pressure solenoid valve, it is essential that its leakage rate be zero. How is the leakage rate of such a solenoid valve determined? It is based on the negative pressure value of the valve Normally, negative pressure solenoid valves require a very low leakage rate; they are also known as zero-leakage solenoid valves, negative pressure solenoid valves, or vacuum solenoid valves. There are also micro-high-frequency solenoid valves and high-frequency solenoid valves, with a maximum frequency of 100 Hz or 200 Hz ； High-frequency solenoid valves can be used for pressure compensation, as well as as regular solenoid valves to regulate flow and compensate for pressure. High-frequency solenoid valves are cheaper than regular ones and yet reliable. Our leak-free solenoid valves are designed specifically for analytical instruments, environmental testing equipment, biochemical instruments, and custom leak detection devices; they operate in a pressure range of vacuum to 15,000 PSI (104 MPa), with diameters ranging from 0.5 mm to 50 mm, and support a wide range of power sources. Common applications of naval/marine valves include: high-pressure solenoid valves for seawater, high-pressure solenoid valves with zero leakage for seawater; reverse osmosis (RO) systems; fuel transfer systems; seawater/bilge water systems; underwater drones AUVs, deep-sea submersibles, deep-sea drilling platforms, etc. High-pressure solenoid valves that can be used with both gas and liquid. 70MPa solenoid valves, direct-acting high-pressure solenoid valves, zero-leakage solenoid valves.
