ABSTRACT:
A control system for a pneumatic actuator uses pressurized gases, such as air, as the actuating medium. Such gases and particularly air commonly contain moisture which condenses to form a liquid, such as water, which collects in a closed chamber of an expandable chamber assembly in the pneumatic actuator. In cold climates, the water freezes, preventing proper control of the pneumatic actuator. By providing a control system having a valve positioned elevationally higher or in close proximity to a pneumatic actuator and a tube which extends into the closed chamber of the expandable chamber assembly, water which is contained in the closed chamber is expelled from the elevationally lowest portion of the assembly when the valve is shifted to exhaust the air from the control system.
