Emerson Process Management has introduced its Fisher 67CFSR stainless steel instrument airset. It is designed to address the problem of increasing costs to power pneumatic instruments in chemical, manufacturing, hydrocarbon and process industries, and to minimise internal relief valve leakage wherever possible. Intensive laboratory leak testing shows the 67CFSR has zero leakage from the internal relief valve. This benefit alone can save plant resources otherwise used to provide the air, natural gas or inert gas required to power pneumatic or digital instruments. The new pressure regulator boasts a higher setpoint capability (0 to 150lb/in2(g)) and can be used to supply high-tech instruments such as digital valve controllers or rugged high-pressure piston actuators. The extensive use of 316/316L stainless steel for all parts of the 67CFSR regulator assures long life, dependable performance and protection from harsh industrial and chemical environments. Designed with digital instruments in mind, the 67CFSR mounts easily and quickly to control valve actuators, pneumatic or digital instruments.
