Suction Control Valves (SCV)

The suction control valve (SCV) is a vital component in common rail diesel engines, regulating the amount of fuel entering the high-pressure pump. By maintaining stable rail pressure, it ensures efficient combustion, smooth acceleration, and reduced emissions.

A faulty SCV can cause rough idling, hesitation, poor fuel economy, or difficulty starting. Left unchecked, it may also trigger engine warning lights and lead to more serious fuel system issues.

At SensorGal, we supply OEM-fit suction control valves designed to meet or exceed manufacturer specifications. Our SCVs are built for durability and precision, giving you confidence in your engine’s performance.
