Overview
OSIST prEN 12335:2004 is a European pre-standard developed by the Slovenski inštitut za standardizacijo (SIST) focusing on industrial valves, specifically cast iron plug valves. This standard outlines the essential requirements for the design, construction, and performance of these valves, including pressure and temperature ratings, materials, and key operational characteristics. The document addresses both lubricated and soft-seated plug valve types, as well as lined valves, and also incorporates important anti-static guidelines. It applies to cast iron plug valves in short, regular, or venturi patterns, making it a vital reference for manufacturers and industries utilizing these components in their systems.
Key Topics
- Pressure and Temperature Ratings: Specifies acceptable limits for valve seat and body under various conditions to ensure reliability and safety.
- Design and Materials: Covers allowable materials for valve bodies and plugs, including options for steel or cast iron plugs, and outlines design demands for optimal operation and durability.
- Valve Types:
- Lubricated plug valves
- Soft-seated plug valves
- Lined plug valves
- Patterns Covered:
- Short pattern
- Regular pattern
- Venturi pattern
- Performance Requirements: Details operational performance measures to maintain consistent and safe operation.
- Testing and Marking: Requires documented testing procedures and permanent marking for product traceability.
- Anti-static Requirements: Addresses measures to prevent static electricity buildup, essential in many industrial contexts.
Applications
Cast iron plug valves covered by OSIST prEN 12335:2004 are used in a wide range of industrial applications where robust and reliable flow control is required. Key application areas include:
- Water and wastewater treatment plants: For flow isolation and control in municipal and industrial water systems.
- Chemical and process industries: Used for the safe handling of chemicals where valve tightness and material compatibility are critical.
- HVAC systems: Effective in heating, ventilation, and air conditioning pipelines.
- General industry: Suitable wherever durable flow control is necessary, especially where system pressures and temperatures need to align with defined limits.
The inclusion of both lubricated and soft-seated designs ensures suitability for various media and operating conditions. Anti-static features add an extra layer of safety, particularly in environments with flammable or sensitive materials.
