440 Compatibility Table The chart below shows the compatibility between valves and fluids along with their pressure and temperature characteristics. Certain models have a maximum working pressure which differs from that given in this table. In this case, the pressure is shown in the heading for the model number in question. N.B.: Above 32 mm or 1¼" diameters, divide the maximum pressure by 2. If the fluid you are using is not shown in this chart, please contact us.
