The APP Automated Pressure Regulator (APR) is a standard manual pressure regulator modified so that pressure output can be controlled by computer or other electronic means. APP does not manufacture pressure regulators in-house; APP automates regulators purchased by APP at a customer's request, or directly provided by a customer. The regulators that APP automates generally feature a wide pressure range from full vacuum to over 10,000 PSI. After automation, the regulators can move from lowest to highest pressure in approximately 30 seconds (depending on gearing and range of the regulator).
