QUADRANT ASME B16.34 / API 608 BALL VALVE

🔧 Product Description: Quadrant Ball Valve (ASME B16.34 / API 608)
Overview
This is a high-performance, quarter-turn—floating or trunnion-mounted—ball valve designed in accordance with ASME B16.34 and API 608 standards to ensure robust pressure containment and leak-tight operation. Built for demanding industrial environments, its rugged construction meets strict safety and performance benchmarks.
Key Specifications
Standards Compliance:

ASME B16.34: Governs pressure–temperature ratings, shell/thickness requirements, materials, and strength testing 

API 608: Covers metal ball valves used in on–off service, defining bore types (full/reduced), seat testing, and metal seat requirements 

Additional certifications commonly found: API 607 fire-safe design, NACE MR0175 for sour service compatibility
