Spanner Wrench Nut

The Wrench Nut fits around the nut at the top of these valves, fitting its two pins into the top nut's two holes. This provides enough grip to easily remove the top nut so the valves can be serviced. A Spanner Wrench Nut is included with the CHN 2410 II Installation Kit.

To keep your Elemental Analyzer operating efficiently, you should clean and rebuild the Normally Closed Valve periodically. Maintenance instructions are included in your operator's manual. Maintenance of the Normally Open Valve requires a PerkinElmer Service Engineer.
