The valves are operated by the PPCs closed loop electronic control circuit. Feedback is obtained from one or two transducers. The balanced poppet, fast response, and high flow of these two MAC Valves provide outstanding performance characteristics for the PPC.<\/p>\n<p>The PPC controls output pressure by constantly measuring its down stream pressure and comparing it to the command signal. If a higher pressure is commanded the PPC quickly responds by actuating the MAC fill valve, increasing the output pressure until it is equal to the pressure represented by the command signal.<\/p>\n<p>Conversely, if a lower pressure is required, the PPC will energize the MAC exhaust valve, decreasing output pressure until the correct pressure is achieved.
