LIMIT SWITCH REPLACEMENT ABERDEEN CHEMICAL PLANT August 27, 1985 WORK BY: O. cM Process Engineer REVIEWED AND APPROVED BY Veidon E. Messlck Chief Process Engineer VAB.0001098788 LIMIT SWITCH REPLACEMENT ABERDEEN CHEMICAL PLANT TABLE OF CONTENTS I. PURPOSE AND PROCESS DESCRIPTION II. INSTRUMENT SPECIFICATIONS III. DRAWINGS * VAB.0001098789 LIMIT SWITCH REPLACEMENT ABERDEEN CHEMICAL PLANT I. Purpose and Process Description The purpose of this design is to provide the valves in VCM and chemical wash service with accurate indication in the control room of the valve position. The existing limit switches do not provide this accuracy, since they are operated by the position of the actuator and not the actual valve stem. This type of operation does not take into account the possibility of shearing between the valve stem and actuator, which has occurred here in the plant. This poses a potentially hazardous situation for a VCM release. This design will provide each of the designated valves on the reactors and charge systems 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 actuator position is showing closed. A total of 102 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.
