ISO 5211 is an international standard that specifies the connection dimensions for part-turn valves, such as ball valves, to ensure compatibility with actuators. This standard is widely used in industries like oil and gas, chemical processing, and water treatment.
• Standardized Connections: ISO 5211 provides standardized flange connections (e.g., F03 to F60) and drive types (e.g., single-keyway, double-keyway), ensuring easy integration with various actuators.
• Interchangeability: The standard promotes interchangeability between actuators from different manufacturers, simplifying maintenance and reducing the need for custom fittings.
• Torque Specifications: Detailed torque ratings for each flange type ensure reliable operation and prevent misalignment or failure.
GB/T 12232 is a Chinese national standard for gate valves, covering their design, manufacturing, and testing. These valves are commonly used in domestic industrial applications, particularly in water treatment and chemical processing.
• Custom Connections: GB/T 12232 gate valves typically require custom drive mechanisms and fittings for actuator installation, which can complicate maintenance.
• Material and Pressure Ratings: These valves are made from materials like cast iron, carbon steel, and stainless steel, with pressure ratings up to 35 MPa.
• Tight Shutoff: The wedge-shaped gate design provides excellent tight shutoff, making them suitable for on-off control applications.
