The Jamesbury series 7000/9000 flanged ball valve are automated shutoff valves designed not only to meet EN161 and EN264, as approved by TÜV Rheinland, but also provide protection against fire and explosive hazards during the operation of gas- and oil-burning equipment. When the electrical signal is interrupted, or when there is a loss of air pressure, these burner valves close within 1 s to isolate the gas or oil flow. This action may be initiated either by safety trip or normal shutdown sequencing. The units are also suitable for use in safety loops with SIL compliance according to ISO 61508. — Metso Automation Inc., Helsinki, Finland
