A pneumatic control system including at least one flow control line having a connecting line connectable to a fluid line of a pneumatically operated machine, a vacuum line connectable to a vacuum source, a vacuum valve controlling flow between the connecting line and the vacuum line, a pressure line connectable to a source of fluid under pressure, and a pressure valve controlling flow between the connecting line and the pressure line. A pressure manifold defines the pressure line and a first portion of the connection line, and supports the pressure valve, and a vacuum manifold defines the vacuum line and a second portion of the connecting line, and supports the vacuum valve. The vacuum manifold is adapted for replacement independently of the pressure manifold.
