Modelling the operation of a pneumatic actuator in a wet environment

This example will demonstrate how the components of the Wet Air library can be used to model a pneumatic actuator operating in a wet environment. The directional control valve is a subsystem consisting of four variable bore blocks and the double acting actuator is a subsystem consisting of two mechanical progressive motion transducer blocks opposite each other.

Water condensation in the pipes and actuator is caused by moisture in the ambient air. Condensation build-up over time can cause damage to the system.
