Abstract
The valve control means includes valves arranged in a bank for controlling the flow of fluids in a winery, oil refinery or the like. The valves have operating arms located in one x-y plane. In a plane parallel to but spaced from the x-y plane there is provided an x-y plotter which has a projecting pin that can be moved adjacent to a valve arm and rotated by computer control to cause rotation of the valve arm between 'on' and 'off' positions. Where the valve is of the type which requires a linear withdrawal of the arm from its stem after rotation can be effected, the valve arm is provided with an abutment plate and one end is withdrawn by operation of the x-y plotter pin. A very close control of temperature, time or other requirement can be achieved automatically without requiring the attention of an operator.
