Seawater Purification Electric Ball Valve
Electric-actuated ball valve engineered for seawater desalination and brine treatment, available with duplex steel body and titanium trim for high chloride service.
Inquire NowProduct Overview
The electric ball valve is purpose-built for seawater desalination plants, brine concentrators, and high-chloride service. The body uses duplex stainless steel (2205/2507) or titanium with optional super-duplex alternatives, providing excellent resistance to pitting and crevice corrosion in aggressive chloride media.
Paired with a heavy-duty quarter-turn electric actuator and intelligent positioner, the valve delivers tight shutoff (ANSI Class VI) and supports Modbus/Profibus fieldbus for SCADA integration in desalination plants.
Key Features
- Dezincification-Resistant Body: Duplex / super-duplex / titanium body for chloride-rich media
- High Cv Flow Path: Full-bore design minimizes pressure loss across the valve
- Smart Positioner: Integrated 4-20 mA + HART positioner with auto-calibration
- Robust Stem Seal: Multi-layer PTFE/graphite packing for leak-free service
- Fieldbus Ready: Modbus TCP, Profinet, Profibus PA for plant-wide automation
