    We have been having a problem with our Swing Gate Check Valve on our Delayed Coker Heater Charge Pump. It appears to be sticking fairly often when we switch pumps. This results in a heater trip and reverse rotation occurs on the pump.
     
    Does anyone have any good solutions for this? Does anyone use a different type of valve?

    Frequently it happens during the process of putting the pump under warmup.The only way to avoid this is by gradual opening of gate valve with extra cautios sense.
