As an indispensable part of fluid control systems, the importance of gas valves is self-evident. Whether in the chemical industry, petroleum, natural gas transportation, or in the environmental protection, pharmaceutical, food and other fields, gas valves play a crucial role. They are responsible for controlling parameters such as gas flow, pressure, and flow rate, ensuring the safe and efficient operation of the system. Below, we will delve into the characteristics of gas valves. High Sealing Performance: Precise Control from Material to Structure Gas valves have extremely high requirements for sealing performance. Due to the small molecular spacing and strong diffusion ability of gas, any leakage will not only cause a waste of resources but also may have a serious impact on the environment and safety. Therefore, gas valves usually adopt a precise sealing structure and high-quality sealing materials to ensure that the valve can completely isolate the gas and prevent leakage when closed.   Excellent Corrosion Resistance: Solutions for Corrosive Environments in Multiple Scenarios The gas media that gas valves come into contact with are often corrosive, such as hydrogen sulfide and sulfur dioxide. These corrosive gases place higher demands on the materials of the valves. Gas valves are usually made of corrosion-resistant materials such as stainless steel and alloy steel to ensure that the valves can still maintain good performance under harsh working conditions.   Flexible Operation and Quick Opening/Closing: Efficiency Revolution Driven by Intelligence Gas valves require flexible operation and quick opening/closing to meet the system's demand for rapid adjustment of gas flow, pressure and other parameters. For this reason, gas valves are usually made of lightweight materials to reduce the weight of the valve and the operating torque. At the same time, the valve is also equipped with an efficient transmission mechanism and actuator to ensure that the valve can quickly and accurately respond to control signals. Safety and Reliability: Systematic Design from Passive Protection to Active Early Warning The safety and reliability of gas valves are directly related to the safe and stable operation of the entire system. Therefore, in the design and manufacturing process of gas valves, relevant standards and specifications are strictly followed to ensure the quality and performance of the valves. The valve is equipped with a variety of safety protection devices, such as overpressure protection and over-temperature protection, to deal with possible abnormal situations. In addition, gas valves have also undergone strict testing and experiments to ensure that they can operate safely and stably under various working conditions. Strong Adaptability: Customization Capability for Full Working Condition Coverage Gas valves have strong adaptability and can meet the requirements of different media, different pressures and different temperatures. Whether it is high-pressure gas, flammable and explosive gas or corrosive gas, gas valves can provide reliable solutions. In addition, gas valves can also be customized according to the actual needs of users to meet their personalized needs. High Level of Intelligence and Automation: Leap from Single-Point Control to System Collaboration With the continuous development of science and technology, gas valves are also developing towards intelligence and automation. Modern gas valves are usually equipped with intelligent control systems and sensors, which can monitor the operating status of the valve and gas parameters in real time, and make automatic adjustments according to preset programs. This intelligent and automated control method greatly improves the operating efficiency and safety of the system, and reduces errors and delays caused by manual operations.

Consequently, they do not have a capacity rating at a given pressure rise (accumulation), and they are not certified to ASME or any other codes.   Some system applications require relief valves to meet specific safety codes. The system designer and user must determine when such codes apply and whether these relief valves conform to them.   AFKlok proportional relief valves should never be used as ASME Boiler and Pressure Vessel Code safety relief devices.   AFKlok proportional relief valves are not “Safety Accessories” as defined in the Pressure Equipment Directive 2014/68/EU.

This article mainly introduces BA and EP stainless steel pipes. BA (Bright Annealing) and EP (Electrolytic Polishing) are two main surface treatment methods for stainless steel pipes, and their main differences lie in treatment processes, surface finish, corrosion resistance, and application scenarios. 1.Differences in process and Principle BA(Bright Annealing): Bright surface effect is formed on the surface of stainless steel pipes through high-temperature annealing under argon atmosphere protection, with the surface showing a matte finish. EP(Electropolishing): Microscopic protrusions on the surface are removed via anodic dissolution to achieve a mirror-like finish, which significantly enhances corrosion resistance and reduces roughness. BA                                                                            EP     2. Smoothness The surface roughness of BA grade is usually ≤ 0.45 μm, showing a uniform matte finish. The Ra value of EP grade is ≤ 0.15μm, which is close to a mirror-like finish and more suitable for high-purity requirements. 3. Corrosion Resistance EP offers superior corrosion resistance compared to BA, as it removes surface defects and the oxide layer.   4. Application Scenarios BA Tubes: Suitable for applications with moderate purity requirements, such as standard high-purity gas delivery systems and biopharmaceutical equipment. EP Tubes: Used in extreme cleanliness environments, including the semiconductor industry, ultra-high-purity media delivery (e.g., electronic-grade chemicals), and sterile medical devices.

The gas alarm monitoring cabinet is a device used for monitoring gas leaks and triggering alarms. It is widely applied in fields such as industry, chemical engineering, petroleum, and mining. Below is an introduction to it:   • Working Principle: By connecting to gas detectors, the gas alarm monitoring cabinet collects real-time data on gas concentrations in the environment. When the gas concentration reaches the preset alarm threshold, the cabinet triggers an audible and visual alarm. It can also link with other safety equipment for emergency response, such as activating ventilation systems and automatically shutting off gas sources.   • Main Functions: It has a gas concentration monitoring function, which can display real-time gas concentration values; it is equipped with an audible and visual alarm function to provide timely alerts when gas concentrations exceed standards; some cabinets have a data recording and query function, capable of storing historical data on gas concentration changes; it can also realize linkage control, connecting with systems like ventilation equipment and valves.   • Appearance and Structure: It is usually of wall-mounted design. The outer shell is mostly made of SPCC cold-rolled steel plate, and some optional stainless steel materials are available to adapt to different operating environments. Its size varies according to the number of channels. Internally, it generally includes signal input interfaces, signal processing units, display and human-computer interaction interfaces, alarm output and linkage modules, etc.   • Application Scenarios: It is commonly used in places such as chemical plants, oil and gas fields, mines, and laboratories. It can detect gas leaks in a timely manner, prevent accidents such as fires, explosions, or poisoning, and ensure the safety of staff and the stability of the production environment. Currently, the industrial gas monitoring field is facing dual pressures from policy upgrades and technical bottlenecks. At the policy level, the "GB/T 50493-2025 Design Standard for Detection and Alarm of Flammable and Toxic Gases in Petrochemical Industry" will be enforced in 2026, which clearly requires that new projects must be equipped with intelligent detectors with data remote transmission functions. Meanwhile, industry pain points are equally prominent: the homogenization rate of low-end products exceeds 50%, with common issues such as insufficient detection accuracy and high false alarm rates; the high-end market relies on imported equipment, which not only has a long delivery cycle of 3 to 6 months, but also the import cost of core high-precision sensors accounts for more than 30%, imposing a heavy burden on enterprises. In scenarios like semiconductor manufacturing, delayed alarms from traditional equipment may even lead to contamination of process chambers and cause significant economic losses.   In high-end manufacturing scenarios such as semiconductors and biomedicine, leak monitoring of toxic, harmful, and flammable gases is a core link in ensuring production safety. The Intelligent Gas Alarm Monitoring Cabinet launched by Shenzhen Wofly Technology Co., Ltd. is a fixed safety device integrating real-time gas concentration detection, wireless data transmission, and multi-level alarm functions. It can meet the monitoring needs of various gases such as methane and hydrogen sulfide. By combining explosion-proof structure design with IoT technology, it can operate 24 hours a day in a wide temperature range of -40℃ to 70℃, capture abnormal gas concentrations in real time, trigger sound and light alarms, and at the same time link with equipment such as exhaust fans and solenoid valves for rapid disposal. It is widely used in key scenarios such as industrial centralized gas supply systems and electronic specialty gas transmission. "The core of gas safety lies in 'early warning and rapid disposal'," a relevant person in charge of Wofly Technology said. This product not only helps enterprises efficiently meet policy compliance requirements, but also transforms safety management from passive response to active prevention through technological upgrades of 'accurate detection + intelligent linkage'. Against the backdrop of accelerated domestic substitution, such localized equipment with both reliability and cost-effectiveness is providing key support for industrial enterprises to build a solid safety defense line.

Standard Model：GB/T 3733-2008（equal to ISO 8434-1） Normal Model：PC-6-1/4（6 mm Tube×1/4" Male Union） Feature： “A nut, a ferrule, and a fitting body: when tightened, the double edges of the ferrule "bite" into the pipe, forming a metal-to-metal seal. This is the most reliable "weld-free quick-disconnect" for pneumatic and hydraulic pipelines.       Specification Materials & Sealing • Body：Stainless Steel 316 • Ferrule：Stainless Steel • Seal：Metal-Metal + O-ring（The end face of BSPP is optional） Installation ① Cut the pipe and remove burrs → ② Slide on the nut and ferrule → ③ Insert into the fitting body → ④ Tighten 1¼ turns (a sudden change in feel indicates proper seating)   Design Pitfalls to Avoid • Pipe Wall Thickness ≥ 0.8 mm to prevent the ferrule from cutting through • Repeated assembly and disassembly ≤ 3 times; the ferrule is deformed and needs replacement • For vibration environments, use double ferrules (Superbite) or welded fittings

Stainless steel is widely used in construction, medical, and food sectors for its corrosion resistance and aesthetics, but processing causes oxide scale or scratches. Its surface treatment relies on three core technologies, with green and intelligent development emerging. I. Natural Color Whitening It removes black oxide scale (e.g., NiCr₂O₄) and boosts corrosion resistance. Sandblasting uses compressed air to spray glass beads, ideal for large parts like chemical tanks—one petrochemical project saw 3x better epoxy adhesion. The chemical method uses eco-friendly pastes to form a Cr₂O₃ film, suiting precision tools (304 instruments endured over 1,000 hours of salt spray). II. Mirror-Like Brightening It creates reflection via polishing, graded by finish (8K: Ra≤0.1μm, ≥85% reflectivity; 10K: Ra≤0.05μm). Mechanical polishing uses abrasive belts/wheels—an elevator trim project hit 600GU gloss. Electrolytic polishing (stainless steel as anode) treats complex parts evenly, forming a 10-50nm film that lifts corrosion resistance by 2-3x; medical endoscopes saw 90% less bacterial adhesion. III. Surface Coloring Colored oxide films enhance decor, wear resistance (2-3x), and corrosion resistance (3-5x longer salt spray). Chemical coloring (e.g., INCO method) controls ΔE≤1.5 (subway bronze columns lasted 500 hours). Electrochemical coloring adjusts voltage (20V=gold, 25V=blue) for phone frames (HV600 hardness). PVD (vacuum sputtering) offers 20+ colors—high-end watches had HV2000 hardness. Traditional pickling is replaced by laser cleaning (120 tons less waste/year). AI inspects polishing quality; "sandblasting+PVD" is used in home appliances. Future treatments will focus on efficiency, eco-friendliness, and multi-functionality.
