In complex and ever-changing industrial environments, Non Return Valve, a device known as "one-way valve", is protecting the safety and stability of fluid systems with its unique functions. It is carefully designed to allow fluid or gas to flow freely in only one direction, effectively preventing the occurrence of backflow, thereby avoiding unnecessary damage to the system.
In today's era of environmental protection and sustainable development, Low Emission Check Valves have become the new favorite of many industries with their excellent performance. These valves are designed to minimize the leakage of liquids or gases, ensuring that emissions are always kept at the lowest level in industries with extremely high environmental requirements such as oil and gas, chemical processing, and pharmaceuticals, helping companies achieve green production.
In today's industrial field, High Pressure Check Valves play a vital role. They are designed to prevent backflow in systems operating under high pressure (generally over 1000 psi). This innovative technology not only improves the efficiency of industrial production, but also provides a solid guarantee for safe operation in multiple industries such as oil and gas, power generation, and chemical processing.
Flanged Check Valves play a vital role in many industrial fields such as water treatment, oil and gas extraction, and chemical processing. They can quickly and automatically close the valve when the fluid flows backward, effectively preventing the backflow of the medium, thereby protecting the system from damage. In order to meet the diverse needs of different industrial systems, Flanged Check Valves adopt a variety of design forms, such as swing type, ball type, and spring type, each of which is designed to provide the most suitable fluid control solution.
In industrial pipeline systems, check valves are of great significance to maintaining unidirectional flow of media, and Cryogenic Check Valve is a capable member of them.
In industrial pipeline systems, check valves are key components to ensure unidirectional flow of media, and their importance is self-evident. Check valves that meet the API 6D standard have become the first choice for industrial pipeline safety with their excellent quality and performance.
Oil and Gas Exploration and Transportation: Used in pipeline systems containing hydrogen sulfide and highly corrosive media to prevent safety hazards caused by backflow of media, and suitable for Class 150~2500 high-pressure environments26.
In industrial pipeline systems, check valves are key components to ensure unidirectional flow of media, and lug type check valves are one of the most popular ones.
The valve disc moves vertically along the center line of the valve body, and the inlet and outlet channels are linear. The structure is compact and the sealing surface wears evenly. It is suitable for small-diameter pipes of DN15~200mm1.
Oil and gas extraction and transportation: Applicable to highly corrosive oil and gas field pipeline systems containing hydrogen sulfide and carbon dioxide to prevent backflow of acidic media. 2205 duplex steel can withstand high pressure (Class 2500) and high temperature (≤350°C) working conditions58.
Corrosive Media Control: Applicable to acid, alkali and other corrosive media delivery systems. The sealing surface adopts Co-based carbide surfacing technology with excellent corrosion resistance (applicable temperature: -29~550℃, pressure ≤2500LB)13.
It mainly relies on the flow of the medium itself in the pipeline to generate power, thereby automatically opening and closing the valve. Specifically:
