Valves serve as critical control components in long-distance oil/gas transmission systems with these primary applications:

Main Pipeline Functions

◆ Full-port ball valves (API 6D) for mainline blocking

◆ Emergency shutdown valves (ESD) with <10s response time

◆ Check valves to prevent media backflow

Station Applications

◆ Regulating valves for pressure control

◆ Pigging valves for pipeline inspection/cleaning

◆ Metering valves for custody transfer

Special Requirements

◆ Full-welded body construction (no external leakage)

◆ High-pressure ratings (up to Class 1500)

◆ Corrosion-resistant materials for sour service

Key Technologies

◆ Intelligent actuators with remote control

◆ Real-time monitoring systems

◆ Cathodic protection compatibility

◆ Winterization for arctic conditions

Performance Standards:
• API 6D for pipeline valves
• ISO 14313 for quality requirements
• SIL3 certification for safety systems
