Sferaco flange check valve 366 series is suitable for all positions due to the stainless steel spring. The body has an arrow, which indicates respect the flow direction. RF flanges are ISO PN10/16 up to DN150, and ISO PN16 from DN200 to DN300, ISO PN10 over. The valve has a strainer basket made of steel and a 6 mm mesh. The internal design is cylindrical, resulting in weak head loss. Both internal and external sides have anti-corrosion epoxy painting in RAL 5017 blue color with thickness of 100µ.
The disc provides improved hydrodynamics. Disc blocking is prevented by bronze bushing. Available on request is drilled boss for bypass or thickness evaluation. The operation is noise free. The valve has a minimum back pressure for tightness of 0.2 bars.
