3. A WARNING Avoid personal injury and property damage from sudden release of process pressure or bursting of parts Before performing any maintenance operations e Do notremove the actuator from the valve while the valve is still pressurized e Always wear protective gloves clothing and eyewear when performing any maintenance operations e Disconnect any operating lines providing air pressure electric power or a control signal to the actuator Be sure the actuator cannot suddenly open or close the valve Instruction Manual 8510B Valve EMA D251400X012 November 2011 Use bypass valves or completely shut off the process to isolate the valve from process pressure Relieve process pressure on both sides of the valve Drain the process media from both sides of the valve e Ventthe power actuator loading pressure and relieve any spring precompression e Use lock out procedures to be sure that the above measures stay in effect while you work on the equipment e The valve packing box may contain process fluids that are pressurized even when the valve has been removed from the pipeline Process fluids may spray out from under pressure when removing the packing hardware or packing rings or when loosening the packing box pipe plug e Check with your process or safety engineer for any additional measures that must be taken to protect against process media Packing Maintenance Key numbers are referenced in figure 3 unless otherwise indicated
