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.
