Understanding EN 12516What is EN 12516?EN 12516 is a series of European standards that specify the design, construction, testing, and marking requirements for industrial valves, including check valves. These standards are developed to ensure that valves used in various industrial applications meet h

Flow Rate and Pressure DropFlow Rate• Definition: The flow rate is the volume of fluid that passes through the valve per unit of time.• Importance: Ensuring the check valve can handle the required flow rate without excessive pressure drop is essential for maintaining system efficiency.• Considerati

Understanding API Standards for Cast Iron Check ValvesAPI 594: Check ValvesAPI 594 is a widely recognized standard that covers the design, materials, dimensions, pressure-temperature ratings, and testing requirements for check valves, including those made from cast iron. This standard ensures that c

Understanding API 594 and ANSI B16.34API 594: Check ValvesAPI 594 is a standard that specifies the design, materials, dimensions, pressure-temperature ratings, and testing requirements for check valves. This standard covers various types of check valves, including swing, wafer, lug, and double-plate

In water treatment facilities, the reliable operation of valves is crucial for ensuring the efficient flow of water and preventing backflow, which can lead to contamination. Check valves, also known as non-return valves, play a vital role in these systems by allowing water to flow in one direction w

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

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

Cast Iron Check ValvesProperties and Performance• Strength: Cast iron is known for its high compressive strength, making it suitable for applications with high static loads. However, it is brittle and not ideal for environments with frequent dynamic loads or vibrations.• Corrosion Resistance: Cast i

Overview of ANSI, DIN, and JIS StandardsANSI StandardsANSI standards for check valves are primarily governed by the American Society of Mechanical Engineers (ASME) and the American Petroleum Institute (API). Key standards include:• ASME B16.34: This standard covers the design, materials, and testing
