Which outcome occurs in pneumatic systems when quick exhaust valve malfunctions and sticks closed after actuation?

💡 Explanation

When a quick exhaust valve sticks closed in a pneumatic system, the exhaust path is blocked because pressurized air cannot rapidly vent, slowing down the actuator stroke. Therefore actuator retraction speed decreases drastically, rather than pressure increase, spikes, or motor shutdown which require either pressure regulation or system overloading.
