Pressure and temperature ratings are shown on the valve data plate.   Installing Valve Recommendations Refer to the valve installation drawing for dimensional information. ã  Installing the valve in the wrong location may cause excessive dynamic torque and damage the valve. When pipeline fluid velocities exceed 20 fps (6.0 m/s) for 12” (300mm) and smaller valves or 12 fps (3.6 m/s) for 14” (350mm) and larger valves, it is recommended to install the valve at least 8 diameters from the nearest upstream elbow or pump. For best performance results, install valve shaft parallel with elbow or pump cross section (see image below). For more specific installation recommendations, contact your local representative or DeZURIK for assistance. ã  Valves with undrilled seat retainers are not suitable for dead-end service without a downstream flange. ã  If possible, install the valve with the shaft horizontal to provide a self-cleaning action on the seat. Install the valve so that the seat will be on the higher pressure side when the valve is closed. The seat side of the valve is marked “SEAT”. Pipeline flow may be in either direction through the valve. ã   Valves with metal seat option must be installed with higher pressure on the seat side  — this is the recommended direction on all other seat options. Use self-centering flat ring flange gaskets. ã  For 2–24 (50–600mm) Class 150 and Class 300 valves, use mating flanges that comply with the same class of ASME/ANSI B16.5. ã  For larger sizes, use flanges that comply with the Class 150, Series A requirements of ASME B16.47.
