Pressure Valves

Pressure valves are installed on high pressure outlet head of injection pump. One valve is used in delivery line leading to each fuel injector.

A check valve is used inside each pressure valve to eliminate any back flow from injector. These check valves reduce secondary injection which can cause misfire or rough idle.
