Understanding Swing Check ValvesStructure and FunctionSwing check valves, also known as tilting-disc check valves, consist of a hinged disc that swings open to allow fluid flow in the forward direction and closes to prevent backflow. The disc is mounted on a hinge or trunnion, allowing it to pivot a

JIS Standard Check ValvesDesign and Performance• Standard Overview: JIS B2071 is a widely recognized standard for check valves in Japan. It specifies the design, manufacturing, and testing requirements to ensure reliability and safety.• Material Specifications: JIS B2071 allows for a variety of mate

STRUCTURAL DESIGN: It may adopt a swing-type structure, where the valve disc is connected to the valve body through a hinge mechanism and can rotate around an axis to open and close. This structure is relatively common in large-diameter valves. It enables the valve disc to have sufficient swing space when opening, and the fluid encounters relatively low resistance when passing through. It may also be a lift-type structure, where the valve disc slides along the vertical centerline of the valve body and opens and closes relying on the pressure of the medium. This type has better sealing performance.

Check valves, also known as non-return valves, play a crucial role in fluid systems by preventing backflow and ensuring unidirectional flow. In complex operating conditions, such as those involving high pressures, high temperatures, corrosive fluids, or fluctuating flow rates, the design and selecti

ISO 14313 Standard OverviewISO 14313 is a widely recognized standard that specifies the requirements for pipeline valves used in the petroleum and natural gas industries. It covers a range of valve types, including check valves, and provides detailed guidelines for material selection, design, and te

Understanding Check ValvesKey Features of Check Valves• Prevent Backflow: Check valves are designed to allow fluid to flow in only one direction, preventing backflow and ensuring unidirectional flow.• Automatic Operation: These valves operate automatically, opening and closing in response to fluid p

In the petrochemical industry, the selection and application of valves are crucial for ensuring the safety, efficiency, and reliability of operations. Check valves and gate valves are two common types of valves that play significant roles in various processes.

In the realm of industrial fluid control, the selection of valves is a critical decision that impacts the efficiency, reliability, and safety of operations. EN (European Norm) standard check valves and API (American Petroleum Institute) standard gate valves are two prominent types of valves used acr
