Five independent calculation modules for flat gate valve (API 6A 20th Ed.) design verification. Each module can be used standalone or combined for complete valve design review.
Body wall per ASME VIII-1 cylinder formula + 1.5Pn hydrotest check
Metal seat sealing: qMF ≤ q ≤ [q] per Valve Design Manual
Flat plate bending thickness verification with K=1.24 free-edge factor
Axial force synthesis and compressive/tensile stress at undercut section
Bonnet flange bolt area verification per ASME B16.34 pressure class
M1: Verify body wall meets ASME VIII-1 minimum
M2: Confirm metal seal pressure in valid range
M3: Check plate bending thickness sufficient
M4+M5: Verify stem stress and bolt area
Run all five modules with one shared set of design inputs and get a consolidated API 6A design review result across shell, seal, gate, stem and bolts.
