Wärtsilä 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.
