Home Forums Coking urgent advise needed Re:urgent advise needed



We are facing lot of problem while opening and closing of the valve during feed in and feed out in to that drum .Also while opening/closing it take high torque to operate this MOV.There must be lot of coke deposit in the seat body and bellow of the SP6 probably and making the motor to exert high torque.We have reached a stage where we fear motor may get damaged so we are to remove the SP6 and replace with another spare SP6.
I agree with all your views becuase we dont know whether switch valve may pass or not.
