Pin shear stress verification for the stem-to-ball pin connection in fixed-shaft ball valves per mechanical design standards.
Open Calculator →
Calculates shear stress on cross pins connecting stem to ball.
Handles multiple pins distributed around the stem center.
Includes pin radial position for accurate torque-to-force conversion.
Instant judgment: tau_pin vs. allowable shear stress for pin material.
Directly uses total stem torque M for force on pin group.
One of 12 modules in the complete Ball Valve Design Calculation suite.
Input total torque, number of pins, pin circle radius, pin diameter, and allowable shear.
F per pin = M / (n * r) from torque and pin geometry.
tau_pin = F / A_pin for total pin shear area.
Compare tau_pin to [tau]; must pass for pin connection reliability.
