Duplex Globe Valve
WDL Duplex Globe Valve provides controlled throttling and positive process isolation for seawater and desalination systems and offshore and marine pipelines. Connections, trim and operation are selected to the project conditions.
Description
Duplex Globe Valve
WDL Duplex Globe Valve provides controlled throttling and positive process isolation for process systems that need high strength with resistance to chloride pitting and stress-corrosion cracking. Duplex stainless steel combines austenitic and ferritic phases for chloride service that requires higher strength than 300-series stainless steel.
