API 6D Trunnion-Mounted High-Pressure Ball Valve Cutaway (8 Bodies)
Split-body API 6D / ASME Class 600 (PN100) trunnion-mounted pipeline ball valve (DN100) with quarter cutaway through the main body, bolted closure adapter, and stuffing-box bonnet exposing the AISI 316 ball plug, spring-loaded PEEK seats, lower trunnion pin, and anti-blowout stem.
In high-pressure oil and gas transmission pipelines (ASME Class 600 / PN100), trunnion-mounted ball valves anchor the spherical plug on top and bottom bearings so line pressure is absorbed by the trunnions while spring-energized seat rings maintain a bidirectional seal against the ball. The cutaway reveals the stepped seat pockets, 12 spring holes per seat ring, lower trunnion pin, and anti-blowout stem shoulder.
1. Geometry & FEA Mesh
- •8 independent subassemblies (21 solids total): main flanged body (cutaway), closure adapter body (cutaway), 12× M20 body studs with 24 hex nuts, AISI 316 full-bore trunnion ball plug, upstream & downstream spring-energized seat rings, lower trunnion bearing plate with 6 bolts, anti-blowout stem & ISO 5211 bonnet (cutaway), and 5-spoke handwheel.
- •Zero CAD Collisions Gate verified: 0.000 mm³ overlap across all components.
2. Loads & Boundary Conditions
- •Stepped internal seat pockets, flange bolt clearance holes, and relief scallops on the center body flanges.
3. Simulation Results & Findings
- ✓All 8 valve subassemblies load with distinct industrial steel, stainless, PEEK gold, and safety-red handwheel colors.
