Why steam purge type of isolation valves are required for the heater charge pump? What is the operating temperature of your pump? In normal cases the charge pumps are operated in the range of  300 to 370 deg C, which is not the coking temperature of the feed. We are using normal gate valves for isolation of our charge pump in our units since last several years without any problem.
