"In recent years, with clean energy becoming a hot topic, the hydrogen industry has received increasing attention. On one hand, there is a growing demand for hydrogen in the market; on the other hand, industrial valves involved in hydrogen applications may have certain safety hazards. In this rapidly evolving industry, ensuring safety must consider various aspects, such as material selection, design verification testing, and fugitive emission testing. Hydrogen is the smallest known molecule in nature and as an energy source, it has unlimited application potential. Hydrogen gas is extremely flammable, and hydrogen valves play a crucial role in controlling hydrogen flow, ensuring the safety of personnel, equipment, and the environment. Info@geko-union.com   01 Valve Selection - For valves used in hydrogen conditions, correct selection is absolutely essential for equipment safety and reliable operation. Common types of hydrogen valves include ball valves, globe valves, and check valves. Ball valves are an ideal choice for on-off functions, with excellent shut-off capabilities for effectively isolating hydrogen. Globe valves offer precise control and regulation functions, commonly used at nodes in hydrogen systems requiring modulation. Check valves prevent backflow, protecting system safety, and play an important role in maintaining the overall integrity of hydrogen systems. When selecting hydrogen valves, it is necessary to follow standards such as API 600, API 602, or ASME B16.34 to ensure that the valves are properly matched with the system and operate normally. 02 Basic Materials - Choosing the right raw materials is essential for manufacturing hydrogen valves to ensure equipment safety and reliability. Common materials include stainless steel (ASTM A351 CF8M), nickel-based alloys (ASTM B564, N10276), and titanium (ASTM B348). These materials all have characteristics of hydrogen embrittlement resistance and are well suited for challenging hydrogen conditions. Several standard associations including ASTM International, the American Petroleum Institute (API), and the American Society of Mechanical Engineers (ASME) provide guidelines on material selection and compatibility for hydrogen conditions, which are highly valuable references. 03 Design Verification Testing - Safety is paramount, especially for hydrogen valves that must withstand the extreme challenges posed by this active gas. This means withstanding high pressures, preventing leaks, and effectively controlling fluids to minimize potential risks and protect life and property. Valves for hydrogen conditions need to undergo design verification testing before use to confirm that they can perform their intended functions and operate reliably under demanding conditions. Recommended specific test types include engineering design calculations and simulations, as well as pressure tests. These tests can serve as simulated functional tests, evaluating the overall integrity and sealing performance of valves under high pressure and repeated cycling. It is recommended to use automated cycling operations to reduce personnel safety risks. For hydrogen valves, the current trend is to use gas pressure tests in proportion to static water pressure tests. The main reason is that water molecules may not reveal some subtle defects in low-pressure tests. Moreover, for some valve designs, water should not be used as the test medium. Inert gases significantly improve test sensitivity. Additionally, it is necessary to conduct tests using clean, dry air, nitrogen, helium, argon, or even hydrogen to simulate actual operating conditions. Test operators must be very familiar with the associated risks and preventive measures. High-pressure gas tests should consider using protective enclosures. Cryogenic tests are essential for verifying valve low-temperature performance, especially for hydrogen valves. Valve design and verification testing must comply with standards such as API 598 and ASME B16.34. In practical operations, it is often necessary to extend the prescribed test time or use higher-than-standard test criteria to obtain more robust assurance. 04 Fugitive Emissions - For hydrogen valves, the primary concern in testing is not only functional tests, gas pressure tests, and cryogenic tests. To ensure that valves remain functional even under worst-case scenarios, fugitive emission testing and fire tests are also necessary. For cost-saving considerations, can functional tests and fugitive emission tests be combined? If valves can perform their functions under the most extreme conditions, it can reduce leaks, pollution, and even prevent accidents. When conducting fugitive emission testing for industrial valves in hydrogen conditions, specialized test procedures must be followed to ensure the safety of personnel and the environment. Helium leak testing using mass spectrometry or other gas detection techniques is a commonly used, highly sensitive method for valve leak testing. Typically, ASME V detection is used for fugitive emission testing. This method is advantageous in detecting extremely weak leaks that are not detectable by general-purpose signal measurement instruments, thereby confirming whether valves meet strict leakage standards and reducing the risk of fugitive emissions. Moreover, fugitive emission testing must comply with standards such as ISO15848-1 and API 622/624 to ensure that hydrogen valves meet environmental protection and safety requirements. Conclusion - In the hydrogen industry, doubling attention to all related aspects is necessary to ensure safety, including material selection, design verification testing, fugitive emission testing, valve selection, and assessing potential safety threats based on specific application scenarios. As manufacturers, shareholders, and owners, it is essential to prioritize and manage all aspects accordingly, following relevant industry standards and best practices to achieve the highest safety standards, making hydrogen a reliable, sustainable, and safe energy source. Despite the continuous expansion of the hydrogen industry, the commitment to safety remains the cornerstone of its development prospects, as only safety can win public confidence in this active energy source."     GEKO is a global leading manufacturer of valves and accessories, catering to various markets including natural gas infrastructure, downstream oil and gas industries, industrial and energy transition, pipeline systems, and power transmission infrastructure.

It is important to install the valve in the pipe as intended    to achieve optimal performance. If there are any questions, please contact us. info@geko-union.com   The Series can be configured for unidirectional or bidirectional flow. The preferred flow direction and high pressure side is indicated on the valve. Proper attention must be paid to    ensure that the valve is installed according to the preferred flow   direction and designated high pressure side. The preferred flow direction is indicated on the nameplate or valve.   The severe service ball valve is designed to handle entrained    solids and the corresponding abrasive/erosive conditions that are associated with such applications. Depending upon the specific     application, the M1 may be equipped with purge port and/or flushing ports in order to flush particulates from the body cavity, prevent scaling, or remove accumulated media. Please refer to the trim of your specific product for the corresponding seat design and presence of such ports. Proper trim and maintenance greatly extends the life of the valve in these harsh environments   Special Conditions for Safe Use The following factors must be carefully considered in order to ensure the valve is compatible with the atmosphere in which it   is applied. The system designer and/or end user should formally address each severe service ball valve and carefully document the reasoning behind specific measures taken to ensure continued compliance throughout the life of the severe service ball valve.   Material Considerations Titanium is not to be used in Group I mining applications and     Group II Category 1 equipment, due to the potential of ignition from sparks caused by mechanical impacts. Please consult factory for details regarding material limitations   Temperature Considerations The Series severe service ball valves are designed in accordance with ASME B16.34 pressure/temperature ratings and are suitable for operating temperatures up to 593 °C (1,100°F), depending on the materials of construction. Custom designs are  available upon request and the pressure and temperature ratings will be marked on the valve tagging. Service media should be considered when evaluating pressure and temperature ratings. The system designer is responsible for ensuring the maximum temperature, either inside the valve body or on the external surface, will remain well below the ignition temperature of the atmosphere. Additional protective devices may be required to ensure a sufficient thermal safety margin including but not limited to: thermal shut off devices and cooling devices. For operating temperatures above 200°C (392°F) Bray recommends thermal insulation of the valve body.   Static Electricity Considerations Where the process medium is a liquid or semi-solid material with a surface resistance in excess of 1 G-ohms, special precautions should betaken to ensure the process does not generate electrostatic discharge. This may be done through ensuring the   flow rate of the process media remains below 1 m/s or providing sufficient discharge points along the process path to eliminate electrostatic buildup. Appropriate grounding may be necessary through the use of grounding straps or other means. Stray Electric Current Considerations When the severe service ball valve is used near sources of high   current or magnetic radiation, a secure bonding to earth ground should be made so as to prevent ignition due to inductive currents or a rise in temperature due to these currents.     Entrained Solids & Process Media Special consideration should be made regarding the filtration of the process medium if there is a potential for the process medium to contain solid particulates. The process medium is   recommended to be filtered to allow particles no greater than 1.0 mm in diameter through the valve assembly where there is a high probability of solid particulates. Larger particulate sizes may be deemed appropriate based on the possibility of particulates within the process medium and the area classification. The decision regarding filtration levels and limits should be well documented by the system designer and/or end user to ensure continued compliance through the life of the valve.   HAZARD FREE USE   This device left the factory in proper condition to be safely installed and operated in a hazard free manner.

GEKO's latest design, the new knife gate valve with blowout holes, is capable of handling high-speed flow, high viscosity, and media containing particulates. This innovation significantly extends the valve's service life, particularly due to its blowout holes and bottom component design, which also makes maintenance much more convenient. I.Built-in Scraper at Packing: The built-in scraper at the packing primarily enhances sealing performance, reduces leakage, extends valve service life, ensures structural stability, and facilitates easy processing and installation.   1. The design of the built-in scraper at the packing of the knife gate valve effectively improves the sealing performance by incorporating a scraper within the packing. This design leverages the physical characteristics of the scraper, such as an arc-shaped inclined surface that closely adheres to the valve body and extends along the valve plate, and a C-shaped cross-section fixed by the knife seat. This makes the overall structure easy to process and install while maintaining structural stability and resistance to deformation over prolonged use. Such a design maintains consistent cleaning efficacy, thereby reducing leakage and enhancing equipment operational efficiency.   . Additionally, the built-in scraper exhibits strong wear resistance, with the sealing surfaces of the knife plate and base made from hard materials. It can handle high-speed flow, high viscosity, and media containing particulates. When dealing with particulate-laden media, the wear-resistant materials of the scraper help to reduce wear and leakage issues, thereby increasing the reliability of the valve. Dual-Sided Scraper Design of the Valve Plate:   Enhanced Sealing Performance: The knife gate valve boasts excellent sealing performance, with gaskets made from either metal or elastic materials to effectively prevent media leakage. This design ensures a significant improvement in the sealing performance between the valve plate and the seat during opening and closing operations, thereby reducing the likelihood of media leakage. High Adaptability: The knife gate valve exhibits good wear resistance, with both the valve plate and the base's sealing surfaces made from hard materials. This allows the valve to handle high-speed flow, high viscosity, and media containing particulates. This design makes the knife gate valve more reliable when dealing with particulate-laden media, reducing wear and leakage issues Extended Service Life: The knife gate valve design considers factors that extend its service life. For example, the bottom end of the valve plate is processed into a blade shape, which can cut through soft materials while ensuring smooth opening and closing. Additionally, a hard PTFE scraper is installed at the upper end of the valve plate to prevent abrasive substances such as dust and gravel from entering the packing box, significantly improving the lifespan of the valve plate.   3. Unique Design Compatible with Both Hard Sealing and Soft Sealing Structures The advantage of having both hard and soft seals in a knife gate valve lies in the flexibility and adaptability it offers, allowing the valve to meet different operational environments and sealing requirements.   By integrating both hard and soft seals in the same valve, users can choose according to specific operational conditions and requirements. For instance, in situations demanding high wear resistance and high-temperature performance, a hard seal is preferred; whereas in cost-sensitive applications or those requiring frequent seal replacements, a soft seal is more suitable. This design provides greater flexibility, enabling the valve to adapt to various working conditions while maintaining excellent sealing performance and lower costs.   Additionally, this design can extend the valve's service life to a certain extent. Since hard and soft seals each have their own service life, a compatible design can balance the usage of both, thereby prolonging the overall service life of the valve.
