The NX15 lower offers a great foundation for an extremely lightweight, easy to maneuver rifle. Utilizing high performance components and precision manufacturing; CNC machined from 7075-T6 billet materials, the NX15 lower is held to strict tolerances and quality controls.
The egr valve is usually located on the intake manifold or head. There is a diaphram in the egr valve. The valve uses manifold vacuum on the diaphram to lift or close a valve allowing exhaust gas to enter the intake manifold. An easy test for the diaphram is to remove the vacuum line that runs to the egr valve.You can normally reach the diaphram area with your finger.here is a diaphram in the egr valve.

Depending on the engine and driving conditions, the ECÎ¼ will control the EGR Solenoid which will operate the EGR Vacuum Îodulator to regulate the opening and closing of the EGR Valve. The EGR system on recently built vehicles uses a step motor to control the flow rate of EGR from exhaust manifold. This motor has four winding phases. It operates according to the output pulse signal of the ECÎ¼. Two windings are turned ON and OFF in sequence.
