During a fire, difficulties in isolating pumps safely from associated storage vessels and tanks can fuel the fire. For these applications, consider EBVs to protect:
• Pumps taking suction from vessels containing LPG
• Hot pumps (operating above 600°F), connected to large reservoirs of hydrocarbons
• Critical, long procurement lead-time pumps connected to large reservoirs of fuel
In these services, several facilities have begun using thermally-activated actuators on fire-safe butterfly valves. (A report about this application is listed under References.) Do not install the valve and actuator over the pump seal because the seal is the most likely point at which a fire may start. Locate the valve and actuator a minimum of six feet from the pump seal and outside any other fire zone.
