Typical applications of ultra-high pressure, high-frequency, zero-leakage solenoid valves: In light of product upgrades and the need for rapid development and testing of products in various industries, there is a particular need to verify materials as well as the reliability of the products； In fluid control systems ； They are often used in applications that require automation. When conducting voltage resistance tests, pulse pressure tests, or pressure regulation, ultra-high pressure, high-frequency solenoid valves are needed as substitutes for proportional valves and servo valves. The control response of proportional valves is not as fast as that of solenoid valves. High-pressure, high-frequency solenoid valves can operate at frequencies of up to 200 Hz and handle pressures exceeding 60 MPa. In terms of airtightness, solenoid valves offer better performance than proportional valves and servo valves; they can achieve a leakage rate of 10-8 ml/s, which means virtually zero leakage” ； When valves are used in biochemical analysis instruments, high-frequency, zero-leakage solenoid valves offer significant advantages. In particular, the solenoid valves produced by Shenzhen Deteng Electromechanical Equipment Co., Ltd. feature an optimized design for the part of the valve that comes into contact with the medium; there are no dead corners, and even the interior cavity of the valve is designed as a concave spherical surface. This ensures that no residues remain after the biochemical medium passes through the valve, thus preventing secondary contamination. No cleaning process is required after analysis, as no residues stay in the valves. For media that tend to crystallize, the spherical design of these solenoid valves prevents any residue from forming, thus avoiding crystallization. Especially for precision analysis instruments, it is essential to use solenoid valves with no dead corners and a spherical design; therefore, it is necessary to work closely with Shenzhen Deteng Electromechanical Equipment Co., Ltd. to develop customized solutions through joint research and discussion. Ultra-low temperature, high-pressure solenoid valve, equipped with special materials; minimum operating temperature: -250℃ ； High-pressure ultra-low temperature solenoid valves are designed using special control principles, featuring direct-acting switch control for fast response times. The maximum operating pressures vary depending on the flow rate: 10 Mpa, 70 Mpa, 103.4 Mpa… In today’s economic framework focused on reducing carbon emissions, hydrogen energy will become one of the key energy sources. To meet the space constraints imposed on equipment, hydrogen needs to be stored and transported in liquid form; this liquid hydrogen is in an ultra-low temperature state, and therefore ultra-low temperature solenoid valves are required for such storage and transportation tasks. Our solenoid valves can meet these requirements, offering a service life of over 1 million cycles along with zero-leakage reliability. Ultra-low temperature high-pressure solenoid valves are core components in the storage and transportation of liquid hydrogen. Key technologies for the production, storage, and transportation of liquid hydrogen; high-frequency solenoid valves, zero-leakage solenoid valves, high-pressure solenoid valves. High-frequency solenoid valves are suitable for use as solenoid valves in pressure regulators and flow regulators. The zero-leakage high-frequency solenoid valves produced by Shenzhen Deteng Electromechanical Equipment Co., Ltd. can be used in both pressure regulators and flow regulators. Since they are high-frequency solenoid valves, they have a lower leakage rate compared to other type of valves such as proportional valves, stepper valves, and servo valves, and they also offer faster response times. Therefore, our zero-leakage high-frequency solenoid valves are more suitable for use in pressure compensation, flow compensation, as well as in pressure regulators and flow regulator valves. Moreover, our valves can handle higher working pressures, up to 103 MPa and 70 MPa. They are high-pressure solenoid valves that can be used with both gases and liquids. 70MPa solenoid valves, 103Mpa high-pressure solenoid valves, direct-acting high-pressure solenoid valves, zero-leakage solenoid valves.

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.
