Shenzhen Deting Electromechanical Equipment Co., Ltd.: Yes, we offer high-tech electromagnetic valves with high pressure and zero leakage. Question: Why is it possible to achieve zero leakage at high pressure? Could you explain the working principle of a solenoid valve? Shenzhen Deteng Electromechanical Equipment Co., Ltd.: Our high-pressure zero-leakage solenoid valves feature a conical sealing structure composed of a rectifying coil together with an FKM or PEEK elastic plunger; the contact sealing surface is fan-shaped. This series of solenoid valves has only these 3 moving parts, which enables us to achieve zero error and zero leakage. Question: In which industries or devices are your company’s high-pressure, zero-leakage solenoid valves typically used? Shenzhen Deteng Electromechanical Equipment Co., Ltd.: Our high-pressure, zero-leakage solenoid valves are suitable for use in instruments or equipment that operate under high pressures with gas-liquid media, require precise measurements, and demand zero leakage. They are ideal for applications where a stable power supply is necessary, where high demands exist regarding the solenoid valve’s power consumption and leakage levels, and where strict requirements are placed on the temperature rise of the equipment. In terms of manufacturing processes, we continue to prioritize zero leakage and a long service life for these valves. Question: What is the maximum pressure that this high-pressure, leak-free solenoid valve produced by your company can handle? What’s the power? What is the external volume? Shenzhen Deteng Electromechanical Equipment Co., Ltd.: The maximum pressure that our high-pressure, zero-leakage solenoid valves can handle is 10,000 PSI, which is equivalent to 70 MPa or 700 bar. All of our solenoid valves are subjected to quality checks using ultrasonic leak detection and nitrogen spectroscopy methods to ensure absolutely no leakage. These valves are about the size of an egg in terms of dimensions – 3*6 cm in width and height. Of course, we offer a wider range of power voltages for customers to choose from, which makes it easier to integrate these devices into various systems. Question: How does your company’s solenoid valve achieve zero leakage? Shenzhen Deteng Electromechanical Equipment Co., Ltd.: Our high-pressure solenoid valves have only 3 moving parts. We have introduced innovations in terms of the sealing structure – we use a conical (funnel-shaped) sealing design, with the sealing surface being fan-shaped. This provides large contact area with the sealing surface and facilitates the removal of debris, which enables us to achieve valves with zero leakage ； Only by reducing the likelihood of measurement errors in the first place, and by using materials of high purity such as FKM, Teflon, PTFE, etc. – materials that are not of inferior quality like those produced domestically – can we ensure high precision. Moreover, using freshly processed materials that are shaped through laser cutting helps to minimize waste, which is essential for achieving efficiency ； Currently, in China, molding or stamping is used for production. In many cases, scrap and waste materials are collected and then remolded for reuse, which fundamentally changes the reliability and stability of the material. As a result, when faced with pressure and temperature fluctuations, the performance of elastic sealing materials such as FKM and PTFE is not comparable to that of our solenoid valves! Question: Do the solenoid coils of your company’s products burn easily? Shenzhen Deteng Electromechanical Equipment Co., Ltd.: Hello, you’ve touched on our key technical processes here. For our solenoid valves, the copper used in their coils is of the TUMn grade, which ensures high electrical conductivity, low resistance, and reduced heat generation. Moreover, rectifier and freewheeling components are added to the entire coil circuit; this not only maintains high conductivity and low heat production but also helps prevent the coils from being damaged by sudden current surges. As a result, our solenoid valves rarely experience coil damage or excessive heat generation. Question: What are the features of your company’s high-pressure, zero-leakage solenoid valves? Shenzhen Deteng Electromechanical Equipment Co., Ltd.: As for our solenoid valve products, at first glance it might seem that they have a small size and excellent surface finish; but is that really all there is to it? In fact, many engineers in China overlook several key technical parameters of solenoid valves ； For example: What is the power consumption of the solenoid valve? Currently, most valves available on the market have a power rating of several dozen watts, with all of them having a power level of over 10W. 2. The switching response time of solenoid valves: this refers to the time it takes for a solenoid valve to open or close a valve in response to a command. In China, 95% of solenoid valves have a switching response time of around 2 seconds (5 seconds or more), whereas our solenoid valves typically have a switching response time within the range of 4–16 milliseconds (1 millisecond = 1/1000 second) ； 3. Duty cycle – it is estimated that domestic solenoid valve manufacturers rarely focus on this as a research area. 4. Vacuum level – this performance parameter is even less likely to be studied by domestic solenoid valve manufacturers. In summary, if you need accurate costs and a reliable manufacturing process, it is generally recommended that you choose our company’s solenoid valves. If you are an enterprise with a sense of social responsibility, committed to improving the quality of the industry and supporting current environmental protection policies, I suggest choosing our solenoid valves, as they always adhere to principles of environmental protection and high performance!

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. A high-pressure solenoid valve that can be used with both gas and liquid. 70MPa solenoid valve, direct-acting high-pressure solenoid valve, zero-leakage solenoid valve.
