The PacE Flow Controller has a sensitive dial for controlling set points to deliver precise pressure control (0.2% from set point within the full range). n Constant Pressure. The flow controller valve responds immediately to changes in air demand, providing consistent pressure at point-of-use. n Reduced Cycling. Pneumatic system: 1 -compressor, 2 -air receiver, 4 -air treatment unit, 4 -control calve, 5 -actuator (cylinder) …. Air treatment unit (FRL unit): 1 -air filter with water separator, 2 The controller processes the signals received and issues a pneumatic control signal to the control valve. The compact control equipment from the Series 420 is designed according to the modular-assembly principle and can be com- bined with various controller modules and additional modules. The air pathway that exits in this (default) condition, connects the A2 port with the E (Exhaust) port and blocks the P1 port. In this condition air can only move from the actuator, through the A2 port to the E (Exhaust) port. The E port provides a means for air to exhaust to the atmosphere.(See figure 1.6) Fig 1.5 P1 A2 E Fig. 1.5 The valves that are used to control the pressure, direction, and flow rate of compressed air are called pneumatic valves. Pneumatic systems rely on the force of compressed air to transmit power and can be found in countless applications, such as power tools for diesel engines. As the air pressure increases, the compressed air begins to push Directional air control valves arethe building blocks of pneumatic control. Symbols representing these valves provide awealth of information about the valve it represents. Symbols show the meth-ods of actuation, the number of positions, the flow paths and the number of ports.

A pneumatic system is a system that uses compressed air to transmit and control energy. Pneumatic systems are used in controlling train doors, automatic production lines, mechanical clamps, etc (Fig. 1).

For instance, Clip-pard's Pneumatic Programmable Controller is a sequen-tial controller that provides step-by-step system opera-tion. It consists of a clear acrylic manifold for mounting sequence valves and other such components in a com-pact, efficient package.
