Pneumatic Actuator with Humidity

This example shows how the Simscape™ Foundation Library moist air components can be used to model a pneumatic actuator operating in a humid environment. The Directional Valve is a subsystem composed of four Variable Local Restriction (MA) blocks, and the Double-Acting Actuator is a subsystem composed of two Translational Mechanical Converter (MA) blocks in opposite mechanical orientation.

Water condenses in the pipes and actuator due to the humidity in the environment. Accumulation of condensation over time may result in damage to the system.
