Chapter 1 Valve Oven Overview Installation and Power Requirements When up to two Valco Purged valves are required (e.g. applications with Pulsed Discharge Detector), this option has to be selected for their housing. For more informations, refer to Valve Oven Components. NOTE When any Valve box (heated or unheated) is configured with valves, these are factory tested to verify actuation but are NOT plumbed. Plumbing can be performed upon availability of plumbing diagrams. Materials needed: Sho
