F540 rate-of-flow pilot
The Meggitt F540 rate-of-flow pilot is designed for use in those fuelling systems requiring a “topping” rate control to override the primary pressure control. This may be desired due to flow-limitations on meters or filters. It is easily adjusted during flow conditions, and is very simple, using a polished, plated piston (no diaphragm) with a Teflon seal for low friction and long life. A typical application schematic is shown on the back page.
