10-2 EB 3018 ENDecommissioningRisk of hearing loss or deafness due to loudnoise.Noise emission (e.g. cavitation or flashing)may occur during operation caused by theprocess medium and the operating condi-tions.Î Wear hearing protection when workingnear the regulator.Crush hazard arising from moving parts.The electric actuator contains moving parts(actuator and plug stems), which can injurehands or fingers if inserted into the actuator.Î Do not insert hands or finger into theyoke while the valve is in operation.Î Disconnect the supply voltage and pro-tect it against unintentional reconnectionbefore performing any work on the con-trol valve.Î Do not impede the movement of the actu-ator or plug stem by inserting objects in-to their path.Î Before unblocking the actuator and plugstem after they have become blocked(e.g. due to seizing up after remaining inthe same position for a long time), re-lease any stored energy in the actuator(e.g. spring compression). See associat-ed actuator documentation.Î Before starting any work on the regula-tor, depressurize plant sections as well asthe regulator.WARNING!WARNING! WARNING!Risk of personal injury due to residual pro-cess medium in the regulator.While working on the regulator, residualprocess medium can escape and, dependingon its properties, may lead to personal in-jury, e.g. (chemical) burns.Î Wear protective clothing, safety glovesand eye protection.Refer to the mounting and operating instruc-tions of the electric actuator for more details(see documents listed under 'Referenced doc-umentation' in the 'Safety instructions andmeasures' section).To decommission the regulator for servicework or disassembly, proceed as follows:1. Disconnect the supply voltage from theelectric actuator (see documents listedunder 'Referenced documentation' in the'Safety instructions and measures' sec-tion).2. Close the shut-off valve (1) on the up-stream side of the regulator.3. Close the shut-off valve (6) on the down-stream side of the regulator.4. Completely drain the pipelines andvalve.5. Depressurize the plant.6. If necessary, allow the pipeline and reg-ulator components to cool down or warmup to the ambient temperature.WARNING! WARNING!Note
