D I S T R I B U T E D V A L V E S INSTALLATION & OPERATION NOTE: If system hydrostatic tests are to be performed at pressures exceeding the rated working pressure of the valve, the valve should be pressurized from the upstream side. This prevents exposure of the clapper to these pressures while the body cavity can accept up to 150% rated working pressure. -
