A B S T R A C T A combination pressure regulating and flow control valve which includes a valve body and a cover means having an upstream port and a downstream port, and a fluid flow passage interconnecting said ports. An adjustable pressure regulator valve means is operatively moun- ted in said fluid flow passage. A check valve means is operatively mounted in parallel with said adjustable pressure regulator valve means, and it is operative to check the flow of fluid through said fluid flow passage when fluid is flowing through said fluid flow passage from the upstream port to the downstream port, and force it through the regulator valve means, and to allow flow of fluid through the check valve means when fluid is exhausted into said downstream port and out the upstream pressure port. A double acting, adjustable fluid flow control valve means is operatively mounted in said fluid flow passage which can provide either a meter in action or a meter out action in one direction with a free flow action in the other direction to the flow of fluid through said passage. The double acting, adjustable fluid flow control valve can also provide free flow action condition in both direc- tions without any metering action. An adjustable quick exhaust valve means 18 included for quickly exhausting the downstream pressure through a second parallel fluid flow passage simultaneously with the exhaust of fluid flow through the first named passage and check valve means. The adjust- able fluid flow control means includes a pair of needle valves that can be operatively mounted on a single valve stem, or on a pair of individual valve stems whereby both a meter in action and a meter out action can be provided without any free flow action.
