Complete ball valve design calculation suite: wall thickness, seal force, ball weight, stem torque, stem strength, bolt load, bearing, key, pin and cover stiffness calculators.
Shell wall verification per ASME VIII-1 cylinder formula with 1.5Pn hydrotest
Metal seat sealing: qMF ≤ q ≤ [q] per Valve Design Manual criteria
Ball geometric volume, mass and weight from sphere minus caps and bore
6-component torque synthesis: seat friction, packing, thrust, bearing, weight, O-ring
Torsional shear stress at keyway, flat key driver, plain round and ball sections
Middle flange bolt load per ASME VIII-1 gasket seating and operating
Upper/lower journal, thrust pad and ball support bearing face pressure
Key shear and crushing stress for stem-to-ball connection
Pin shear stress for stem-to-ball cylindrical pin connection
Bottom blind cover deflection and rotation angle under pressure
M2+M3: Verify body wall thickness and seat sealing pressure
M4+M5: Calculate ball weight and stem operating torque
M6+M7: Check stem strength and body bolt load
M10-M13: Bearing, key, pin and bottom cover stiffness
Run each module independently with the appropriate design inputs and get a consolidated ball valve design review result across wall thickness, seal, ball, torque, stem, bolts, bearing, key, pin and cover stiffness.
