Unfailing reliability in hazardous conditions
Extraordinary reliability is required from safety and on-off valves for burner management systems. Safety is a primary concern and unnecessary shutdowns of a heater can cost hundreds of thousands of dollars a day.
Especially in hazardous conditions, safety shutoff valves must close under all circumstances. The on-off valves in front of the burners are responsible for managing the correct heat temperature. For these valves, reliable switching is crucial to keep operational costs low and increase heater efficiency.
The refinery was looking for valves that met these requirements, would perform like new for a long time, and would meet or exceed the standards for tightness and safety established by the European health, safety and environmental (HSE) regulations. The company also wanted valves which could be maintained as simply and quickly as possible, as even regular inspection and maintenance shutdowns are costly.
In addition, the company required the best possible valve sealing to protect the health of its operators and the environment from fugitive emissions of hazardous and toxic fuel gases.
