Gas valve unit

The gas valve unit (GVU) controls the gas feed pressure according to the engine load. In addition, the unit ensures safe maintenance on the engine and performs a leakage test of the automatic shut-off valves before the engine starts operating on gas. In case of hazardous events, the unit will automatically inert the gas line with nitrogen. A gas valve unit is needed for each engine, to control the engine-specific gas pressure. The Gas Valve Units can be installed directly in the engine room.
