How to Select the Right Actuator for an API 6D Ball Valve | Pneumatic vs Electric vs Hydraulic
API 6D ball valves are critical isolation equipment in pipelines. Actuator selection directly impacts system operational reliability and construction costs. This guide comprehensively covers valve selection for sizes ranging from DN50 to DN1200 and pressure ratings from Class 150 to Class 900. It provides a comparative analysis of the three mainstream actuator solutions: pneumatic, electric, […]
How to Interpret a Valve Material Test Report | EN 10204 3.1 Certification, Chemical Composition, Mechanical Properties
When each valve leaves the factory, a material certificate (EN 10204 3.1) is delivered together with the physical product. It covers key data such as: Property Value / Range Chemical composition 9 major elements plus trace elements Tensile properties Re ≥ 250 MPa, Rm = 485–655 MPa Impact toughness -46°C ≥ 20 J Hardness ≤ […]
