PURPOSE AND PROCESS DESCRIPTION II. INSTRUMENT SPECIFICATIONS III DRAWINGS ABD00211015 I LIMIT SWITCH REPLACEMENT ABERDEEN- CHEMICAL PLANT I. Purpose and Process Description The purpose of this design is to provide the valves in VCM service with reliable indication of the valve position in the control room. The existing limit switches do not provide this reliability, since they are operated by the position of the actuator.and not the position of the valve. This type of operation does not account for the 'possibility of shearing the coupling between the valve'stem and actuator, which poses a potentially hazardous situation for a VCM release. This design will provide each of the designated valves on the reactors and charge system with a new limit switch that operates on the position of the valve stem. These new limit switches will provide accurate indication in the control room and eliminate the hazard of a valve being open when it's acutator position is showing closed. A total of 47 valves will be equipped with this new type of limit switch. These limit switches will be mounted on the bracket between the valve and the actuator. Drawings of several different types of valves with the new limit switches are attached. The valves which will be equipped with the new limit switches are listed in Table I. ABD00211016 Reactor 745 + 700 TABLE I Valve Location VCM Charge VCM Charge Main Dump Evac./Rec.
