Control of air pressure in the receiver was described in an earlier section. This section describes various ways in which pressure is locally controlled.<\/font> <\/p>\n<p align=\"justify\"><font size=\"5\">There are essentially three methods of local pressure control, illustrated in Figure 3.24. Load A vents continuously to atmosphere. Air pressure is controlled by a pressure regulator which simply restricts air flow to the load. This type of regulator requires some minimum flow to operate. If used with a dead-end load which draws no air, the air pressure will rise to the main manifold pressure. Such regulators, in which air must pass through the load, are called non-relieving regulators.<\/font> <\/p>\n<p align=\"justify\"><font size=\"5\">Load B is a dead-end load, and uses a pressure regulator which vents air to atmosphere to reduce pressure.
