Which outcome occurs when the poppet valve in a pneumatic actuator experiences stiction?

💡 Explanation

When a poppet valve experiences stiction, that means static friction prevents smooth release, then releases suddenly when force overcomes the stiction, this causes jerky motion. Therefore unpredictable actuator movement occurs, rather than constant venting, decreased force, or overheating, which involve air leakages or physical obstructions.
