Prevents backflow of external water during floods and high tides! Stainless steel flap gate.
The "F4 type" and "F5 type" are stainless steel flap gates designed to prevent backflow of external water during floods or high tides. They excel in corrosion resistance and water resistance, and achieve high pressure resistance by having a spherical surface. The two-point support arm allows for smooth opening and closing, enhancing water tightness. With minimal protrusions, they effectively prevent debris accumulation. The "F4 type" is wall-mounted (all-anchor type), while the "F5 type" is band-fixed. 【Features】 ○ High corrosion and water resistance ○ Direct attachment to pipes possible (F5 type only) ○ Allowable water depth: 3.5m to 5.0m For more details, please contact us or download the catalog.
