Description
Monel Discharge Valve
WDL Monel Discharge Valve provides controlled draining from reactors, vessels and process tanks for process systems that need resistance to hydrofluoric acid, seawater and selected reducing media. Monel 400 is a nickel-copper alloy used for controlled hydrofluoric acid, marine and reducing chemical duties.
