BS 5351 is a British standard that specifies the design, materials, dimensions, operation, performance, testing, and marking of steel ball valves for the petroleum, petrochemical, and related industries. It covers full-bore and reduced-bore valves with one-piece or split-body construction.
• Valve Patterns: BS 5351 covers full-bore and reduced-bore valves, with options for one-piece or split-body construction.
• Pressure/Temperature Ratings: The standard specifies detailed pressure and temperature ratings for different valve sizes and materials.
• End Connections: BS 5351 includes specifications for flanged, butt-weld, socket-weld, and threaded end connections.
• Anti-Static Feature: The design incorporates an anti-static feature to ensure electrical continuity between the valve body, ball, and stem.
• Fire-Tested Design: Valves are designed to comply with fire testing requirements to ensure reliability in emergency situations.
DIN 3352 is a German standard that specifies the design, materials, dimensions, and performance requirements for gate valves. It is widely used in European industrial applications, particularly in sectors such as oil and gas, chemical processing, and water treatment.
• Valve Patterns: DIN 3352 covers a range of gate valve designs, including rising stem and non-rising stem options.
• Pressure/Temperature Ratings: The standard provides detailed pressure and temperature ratings for different valve sizes and materials.
• End Connections: DIN 3352 includes specifications for flanged, butt-weld, and threaded end connections.
• Sealing Performance: The design emphasizes tight shutoff capabilities, with options for metal-to-metal or soft-seated seals.
• Structural Integrity: The standard ensures structural integrity through rigorous design and testing requirements.
