WDL Duplex Gate Valve provides full-bore on-off isolation with low pressure loss when open 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.

Типичные области применения

• Seawater and desalination systems
• Offshore and marine pipelines
• Pulp and paper processing
• Main process isolation
• Full-bore pipeline service

Примечания по выбору

Choose 2205, 2507 or another grade from chloride level, temperature, pressure and required pitting resistance.

Gate valves are normally selected for isolation rather than continuous throttling; confirm wedge, seat and stem design.

Часто задаваемые вопросы

Why select Duplex Stainless Steel for this gate valve?

Duplex stainless steel combines austenitic and ferritic phases for chloride service that requires higher strength than 300-series stainless steel. Final suitability depends on the complete process conditions and the selected valve trim.
