FPV
Wafer Lug Knife Gate Valve
The FPV Wafer Lug Knife Gate valve is designed as a space saving option for corrosive applications. The resilient seat is an elastomer sleeve, available in different materials. The sleeve supports and guides the gate and guarantees full tightness when closed. The valve can be used in either bi-directional or dead end service.
