3 The sealed terminal boxisolates field wiring connections from other areas ofthe instrument and keeps water and harsh atmosphereaway from electronic components. The DVC6200stainless steel version eliminates all diecast aluminumparts, which greatly increases its resistance to thetough, corrosive environments found on offshoreplatforms, within chemical plants, and inside refineryprocessing 2. Fisher DVC6200 Digital Valve Controller Stainless Steel VersionX0350 Proprietary NCF(Non-Corroding Finish)Coating for Steel FastenersStandard steel fasteners such as bonnet bolting,actuator casing bolting, and steel fasteners for Fisherinstruments have NCF (non corroding finish) coating was developed by Emerson AutomationSolutions to greatly improve resistance to corrosionfrom acids, bases, salts, and many other chemicals andto follow the parameters listed in ASTM F1136(Standard Specification for Zinc/Aluminum CorrosionProtective Coatings for Fasteners).

4 NCF coating is apolymer-based coating consisting of multiple coatsapplied to all surfaces of bolts, studs, and nuts. (NCFcoating is not used on steel bolting for temperaturesover 427 C or 800 F). NCF coating is silver or gray incolor and the finish is dull when compared with effectiveness of this proprietary coating designedspecifically for the control valve market has beenproven by actual testing on offshore platforms andaccelerated salt-spray tests in the laboratory. NCFcoated fasteners remain easily maintainable afteroffshore exposure. Original replacement NCF bolting isonly available from Emerson Automation 3.
