The body hydrostatic test should be performed at a pressure 1.5 times the maximum rating pressure in accordance with API6D. c- With the gate in the fully open or closed position the maximum seat hydrostatic test pressure should be performed at a pressure 1.1 times the maximum pressure rating in accordance with API6D. In addition a low pressure pneumatic test of 700KPA should be performed in accordance with API6D. Seats should be tested bi-directionally. 8 . 0 OPERATION & MAINTENANCE Nominal Pressure (Class) Test Pressure at Normal Temperature (PSI) Hydrostatic Shell Test Hydrostatic Seat Test High/Low Pressure Back Seat Gas Seat Test CL150 450 325 325/80 80 CL150 1125 825 825/80 80 CL150 2225 1650 1650/80 80 CL150 3350 2450 2450/80 80 CL150 5575 4075 4075/80 80 CL150 9275 6800 6800/80 80 The valve is only intended to block or allow flow through the pipeline.
